As nowadays customers are adopting cloud-based Infrastructure to deploy applications, it becomes necessary for the providers (like Oracle) to layout a highly secured and monitored environment for building and implementing the product. In order to do so, Oracle provides Cloud Access Security Broker (CASB).

This post covers:

• Overview of Oracle CASB
• Key Features of CASB
• Steps to Register application in CASB
• Benefits of using CASB

Overview Of Oracle CASB

Oracle provides CASB service for security monitoring of various services like VCN, Compartments, Compute, Databases, etc in Oracle Cloud Infrastructure (OCI). CASB in Oracle works over a compartment that means we need to specify a target compartment whose resources we want to be monitored.

Though we need to specify appropriate policies in CASB console in order to securely monitor the resources of destined compartments.

Key Features Of CASB

• Visibility: Provide visibility across OCI services like networking, compute, database, etc.
• Compliance: Monitoring & Reporting for the audit of various actions over services.
• Threat Protection: Automatic threat detection and risk prediction using Machine Learning.
• Data Protection: Protecting data stored in OCI
• Remediation: Automatic resolving threats.

CASB Cloud Services In OCI

• Policy Alerts: Alert and Notifying for a change in resources like Launch & termination of images, db system, instances, etc.
• Security Controls: Securing resources from any irregularity like compute with public IP, LB with Internet gateway.
• Threat Detection: Automatic threat detection and risk prediction using Machine Learning like IP Hopping, anomalies.
• Key Security Indicator Reports: Report generation for key security indicators like IAM changes.
• Export Data & Threat Remediation: Enterprise Integrations with SIEM or ITSM systems.

Note: OCI’s Objective is to deploy the functionality as quickly as possible on cloud and CASB’s Objective is to restrict exposing data, access, and control more than required.

Benefits Of Using CASB

• Continuous security monitoring of various resources in OCI.
• Automated unexpected behavior detection with policies.
• Risk Detection by continuous monitoring.
• Proactive actions against anomalies in OCI services.

Note: To know about the cost of using CASB depending on the various pricing models in Oracle click here.

Steps To Register Application In CASB

Note: Before registering Application in CASB for monitoring, we need to configure a user to CASB.

To follow the steps to configure the user to CASB click here.

Follow the below steps to register Application in CASB

1) Navigate to Platform Services in OCI Console and click Oracle CASB.

2) Select the OCI app from a list of apps and give a unique name to the instance.

3) Now we have to select the type of compartment that CASB monitors and then enter Tenancy OCID and User OCID.

• Tenancy: The root compartment that contains all of your organization’s compartments.
• Compartment under a registered Tenancy: Selecting a compartment from the tenancy that is already registered in CASB.
• Standalone Compartment: OCI compartment that is accessed directly, without first registering the OCI tenancy in Oracle CASB Cloud Service.

4) Click on Test Credentials and then Submit.

5) After some time we can see that the application is registered in CASB.

Note: Before deploying an application on CASB for monitoring we need to specify some policy.

Conclusion

As customers are moving from on-prem to cloud for deploying their applications, it becomes necessary for providers to give away a securely monitored environment in which they can deploy their applications. For this many services are provided by Oracle and one of them is CASB. In this post, I have covered Overview of CASB, Key Features & Benefits of CASB, and steps to register an application on CASB for monitoring.

I hope it will help you understand the concept of CASB in OCI.

CASB is also covered in our OCI Architect Professional [1z0-997] Certification training. To know more about this training click here.

In this blog, we are going to cover the kubernetes overview, the key benefits of using kubernetes, Key Points of kubernetes architecture, kubernetes components. Also, we are discussing what is kubernetes master node & worker node and it’s components.

Note: The kubernetes architecture and it’s components both are part of Certified Kubernetes Administrator (CKA) Certification Exam to know more about the certificate exam topics click here and to know more about the activity guides/hands-on lab exercise you should perform to clear the certification exam click here

What is Kubernetes? 

In organizations, multiple numbers of containers running at a time so it is very hard to manage all the containers together we use Kubernetes. Kubernetes is an open-source platform for managing containerized workloads and services. Kubernetes takes care of scaling and failover for your application running on the container.

Note: To know more about the containers click here

Key Benefits of Using Kubernetes

1) It is highly portable it is compatible with across different platforms.

2) It is very efficient and highly scalable and highly available.

3) In Kubernetes load balancing technique is very efficient so it allows distributing traffic across network very efficiently.

4) It allows storage orchestration and it is self-healing if anything fails it fix that automatically.

Kubernetes Architecture Key Points

1) In Kubernetes architecture, there is one or more master and multiple nodes. One or masters used to provide high-availability.

2) Master node communicates with node using api-server to kublet communication.

3) In the worker node, there are one or more pods and pods contain one or more containers.

4) Containers can be deployed using the image also can be deployed externally by the user.

Kubernetes Components

Kubernetes Master Node

Master Node is a collection of components like Storage, Controller, Scheduler, API-server that makes up the control plan of the Kubernetes. When you interact with Kubernetes by using CLI you are communicating with the cluster’s Kubernetes master. all the processes run on a single node in the cluster, and this node is also referred to as the master. There can be more than one master node in the cluster.

Master Node Components

1) Kube api-server performs all the administrative tasks on the master node. A user sends the rest commands as YAML/JSON format to the API server, then it processes and executes them. The Kube api-server server is the front end of the Kubernetes control plane.

2) etcd is a distributed key-value store that is used to store the cluster state. Kubernetes stores the file in a database called the etcd. Besides storing the cluster state, etcd is also used to store the configuration details such as the subnets and the config maps.

3) Kube-scheduler is used to schedule the work to different worker nodes. it also manages the new requests coming from the API Server and assigns them to healthy nodes.

4) Kube Controller Manager the task of the Controller is to obtain the desired state from the API Server. if the desired state does not meet the current state of the object, then the corrective steps are taken by the control loop to bring the current state the same as the desired state.

There are different type of control manager in Kubernetes such as

• Node Manager, it manages the nodes. it creates new nodes if any node unavailable or destroyed.
• Replication Controller, It manages if the desired number of containers is running in the replication group.
• Endpoints controller, it populates the endpoints object that is, joins Services & Pods.

Kubernetes Worker Node

The worker nodes in a cluster are the machines or physical servers that run your applications. The Kubernetes master controls each node. there are multiple nodes connected to the master node. On the node, there are multiple pods running and there are multiple containers running in pods.

Worker Node Components

 1) kubelet is an agent that runs on each worker node and communicates with the master node. It also makes sure that the containers which are part of the pods are always healthy. It watches for tasks sent from the API Server, executes the task like deploy or destroy the container, and then it reports back to the Master.

2) Kube-proxy is used to communicate between the multiple worker nodes. it maintains network rules on nodes also it makes sure there are necessary rules define on the worker node so the container can communicate to each in different nodes.

3) Kubernetes pod is a group of one or more containers that are deployed together on the same host. Pod is deployed with a shared storage/network, and a specification for how to run the containers. Containers can easily communicate with other containers in the same pod as though they were on the same machine.

4) Container Runtime is the software that is responsible for running containers. Kubernetes supports several container runtimes: Docker, containerd.

In this video blog post, I’ll cover the step-by-step configuration of  How to deploy Azure Virtual Machines (VMs) in Availability Sets and Availability Zone to increase the availability and reliability of your VMs.

If you are not familiar or want to know more about the concepts Availability Sets, Fault domains, Update domains, and Availability Zone, then please read our previous blog.

What Is An Availability Set?

An Availability Set is a logical grouping capability for isolating VM resources from each other when they’re deployed. It is essentially your way of designing how available your cloud infrastructure is going to be in the event of unplanned or planned maintenance. Microsoft gives 99.95% SLA if you deployed your VMs in Availability Set.

Deploy VMs In An Availability Set

Perform the following steps:

 1. Sign in to the Azure portal at https://portal.azure.com.

2. In the Search bar, type Virtual Machines, and then click Add.

3. On the Create virtual machine blade, click Basics. Enter Unique VM Name, VM disk type, User name and Password, Subscription, Azure Resource Group (New or Existing), Azure DataCenter Location (Region), and Select Availability Options to Add Availability set.

4. Click Create New, type the name for the Availability set, select the no. of  Fault Domains and Update Domain, Then click OK.

Fault domains – The group of VMs that share a common power source and network switch. By default, the VMs are separated across up to three fault domains and can be changed to between 1 and 3.

Update domains – Update domains indicate groups of virtual machines and underlying physical hardware that can be rebooted at the same time. By default, 5 domains are assigned. This can be set to between 1 to 20.

5. Leave the rest tabs to their default values and select Review + Create.

Now your First VM is created and deployed in an Availability Set.

Create a new second Virtual Machine and Add to the same Availability Set in the Azure Portal:

1. Repeat the same steps from  1-3 of the previous VM creation and Select the Availability Set (AS demo) in the Availability Set option.

NOTE: Second VM should be in the same Resource Group as the First VM.

2. Leave the rest tabs to their default values and select Review + Create.

Now you have successfully deployed both the VMs in the Availability Set.

3. Check the status of the  Availability Set by going into the Resource Group and select the created Availability Set(ASDemo) resource.

4. Now you can see your both the Virtual Machines are deployed in the Fault Domain and Update Domain.

This is how Azure automatically keeps track of which VMs belong to each domain respectively. Just remember, you may not move a VM from one Availability set to another. This would require you to delete and recreate the VM.

To expand the level of control you have to maintain the high availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region.

What Is The, Availability Zone?

An Availability Zone is a high-availability offering that protects your applications and data from datacenter failures. They are unique physical locations within an Azure region. Each zone is made up of one or more data centers equipped with independent power, cooling, and networking. Microsoft gives 99.99% SLA if you deployed your VMs in Availability Zone.

Deploy VMs In Availability Zones To Protect From Datacenter Level Failures:

Perform the following steps to do so:

1.  Sign in to the Azure portal at https://portal.azure.com.

2. In the Search bar, type Virtual Machines, and then click Add.

3. On the Create virtual machine blade, click Basics. Enter Unique VM Name, VM disk type, User name and Password, Subscription, Azure Resource Group (New or Existing), Azure DataCenter Location (Region), and Select Availability Options to Add Availability Zone.

4. Now select the first Availability Zone for your first VM from the Availability Zone option drop-down list.

NOTE: Not every region has support for Availability Zones. A region can have up to 3 max. Availability Zones.

Check whether the target region has support for Availability Zones or not.

5. Click Next and Leave the Disks Tab to its default value and jump to Networking Tab.

6.  Select Create New from the Public IP option and choose Zone-redundant in the Create public IP address page and click OK.

This will make your VM available for zone redundancy otherwise the VM will behave like in an Availability Set.

7. Leave the rest tabs to their default values and select Review + Create tab, then Create.

Now you have successfully deployed your First VM in the first Availability Zone of East US region.

Create a new second Virtual Machine and Add to the second Availability Zone in the Azure Portal:

1. Repeat the same steps from  1-3 of the previous VM creation.

2. Now select the second Availability Zone for your second VM from the Availability Zone option drop-down list.

3. Repeat the same steps from  5-6 of the previous VM creation.

4. Leave the rest tabs to their default values and select Review + Create tab, then Create.

Now you have successfully deployed your VMs in the Availability Zone of East US region.

[New Feature] In this blog post, I have discussed the new feature that has been introduced by Oracle on 1st June 2020 i.e., Online resizing for block volumes and boot volumes.

Oracle has recently introduced a new feature from which you can now resize your block/boot volumes without any downtime. Boot Volumes and Block Volumes come under the topic Storage.

Storage is one of the 5 Core Services (IAM, Networking, Compute, Storage & Database) of OCI.

If you don’t know What is Block Volume,  then I would highly recommend you to check our previous post here.

Resizing Block/Boot Volume

After this new update from Oracle, you can now increase the size of your Block and Boot Volumes without affecting your running application. This has been a long-awaited update from Oracle. You can try this feature in the free Cloud Account too.

Few points to keep in mind

• Sizing of Block or Boot Volume online without affecting any running application, which means you do not have to take down your application so there is no Downtime.
• This feature is available in all the Oracle Cloud Regions.
• You can access this feature on your currently existing volumes as well as newly created volumes.
• Both Boot Volume and Block Volume can be increased upto 32TB in size.
• You can add 32 Volumes of 32 TB each to an instance.
• After the extension, rescan the disk to extend the partition.
• parted or DISKPART commands can be used.

Steps to Increase the Size of a Block Volume

1. Log in to your Oracle Cloud Account.
2. Open the navigation menu. Under Core Infrastructure, go to Compute and click Boot Volumes.
   
3. In the Boot Volumes list, find the volume of who’s size you want to increase.
   
4. Click on “Edit Size or Performance”.
   
5. Enter the Size you want for the Boot Volume and click on Save Changes.
   

This is how you can increase the size of your Boot/Block Volumes.

In this blog, we are going to cover the Docker Image overview, different layers in Docker Image, what is dockerfile, and the major difference between Docker Image and Container.

Note: Docker Image and layers both are part of Docker & Kubernetes to know more about the Docker & Kubernetes Overview click here

Docker Image Overview

Docker images are the template that is used to create a docker container. Images are read-only template with instructions for creating a Docker container. These are very similar to VM image, VM image is used to create a VM machine on the other hand Docker images are used to create Docker containers. The difference between these images are VM images are very big single file while Docker image is made up of multiple layers.

Docker Image Layers 

Docker image consists of layers built on top of each other. Each layer represents an instruction in the image’s Dockerfile. Docker uses Union File System (UFS) to build an image. The image is shared across containers. This Dockerfile contains multiple sets of commands, each of them is used to creates a layer. Each layer is only a set of differences from the layer before it. The layers are stacked on top of each other.

What Is Dockerfile?

A Dockerfile is a Document file that contains collections of commands that will be executed in the docker environment for building a new docker image. This file is written in YAML Language. A Docker image consists of read-only layers each of which represents a Dockerfile instruction.

Docker Image VS Container

Docker image and Container are closely related to each other the major difference between them is Docker image is collection of File plus metadata which is required to run an application, and a container is a running instance of the image or container is a copy of the image.

Note: Each container has its own writable container layer, and all changes are stored in this container layer, multiple containers can share access to the same underlying image and yet have their own data state.

The post Docker Image And Layer Overview For Beginners appeared first on Oracle Trainings.

Compute is one of the 5 pillars on which OCI is built. Oracle provides compute instances in order to provision and manage Compute hosts.

This post covers:

• Overview of Compute Instances
• Types of Compute Instances
• Different shapes of Instances
• Steps to create & access a Compute Instance (Linux/windows)
• Important Concepts related to Compute

Overview Of Compute Instances

Compute is a Linux/Windows machine created on the cloud with a shape that we can use to deploy various services depending on application requirements. Compute machines have OCPUs, memory, storage, and boot volume attach to it which defines the shape of an instance. We can also attach and detach storage volumes.

In the below video, I have covered the things you must know about Compute in Oracle Cloud Infrastructure (OCI)

Types Of Compute Instances

There are 3 types of Instances in OCI.

1) Bare Metal (BM) Instance: In Which you will get direct access to the underlying hardware. It gives a dedicated physical server for Highest performance & strong isolation. It is used for heavy workloads.

2) Virtual Machine (VM) Instance: VM instance runs on top of Bare Metal hardware. There is a hypervisor on top of Bare Metal server to virtualize it in smaller VMs. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.

3) Dedicated VM Host: It is the combination of Bare Metal and Virtual Machine. In this multiple VMs are running on Bare Metal and the whole server is dedicated to a single host. Till now Autoscaling & Instance pool is not supported in these instances.

Types Of Shapes

Compute Shape is a combination of CPU, Memory, and Local storage. There are several predefined shapes available on oracle cloud Infrastructure.

1) Standard shapes: These shapes provide a balance of cores, memory, and network resources. Standard shapes are available with Intel or AMD processors. These shapes are used for general workloads.

2) DenseIO shapes: It is used for Big Data, large databases, & high-performance local storage is needed. DenseIO shapes include locally-attached NVMe-based SSDs.

3) GPU shapes: Used for hardware-accelerated workloads. GPU shapes include Intel CPUs and NVIDIA graphics processors.

4) High-performance computing (HPC) shapes: designed for high-performance workloads that require high-frequency processor cores and cluster networking for massively parallel HPC workloads. These shapes are available in only Bare Metal instances.

Note: Oracle has recently introduced a new feature of flexible shape in OCI in which you can design shape by yourself

To know more about flexible shape in OCI click here https://k21academy.com/oci69

Steps To Configure Compute Instance

You can create two types of instances a Linux instance or Windows instance. In this example, we will be creating a Linux instance.

Prerequisite: You must create SSH public & private keys using puttygen.exe

To know how to generate SSH keys click here http://k21academy.com/oci51

1) Navigate to Compute under Core Infrastructure and click on Instances.

2) Select the compartment in which you want to create an instance.

To know about IAM and Compartments in OCI click here https://k21academy.com/oci13

3) In the Create Instance dialog, Enter the following

• Name: PoC_K21_Linux_Instance
• OS: Linux/Windows
• Availability Domain: AD1/AD2/AD3
• Instance Type: Virtual Machine/ Bare Metal
• Instance Shape: Eg: VM.Sandard2.1
• VCN Compartment: PoC_Compartmet
• VCN: PoC_VCN
• Subnet Compartment: PoC_Compartment
• Subnet: public/private
• Boot Volume: Select default boot volume (46.6 GB) or you can customize this
• ADD SSH Keys: Select Choose SSH key file or paste your Public key

and then click on Create. After a few minutes, we can see the instance have created

Note: Select Assign Public IP Address box otherwise it will create Public Instance without Public IP.

Steps To Access Linux Instance

We can access the Linux Instance created using putty.exe and to connect to Windows Instance we use RDC (Remote Desktop Connection) which we will cover later in the post.

1) Copy the public IP Address of Instance created

2) Open putty.exe and paste the ip address as shown below and add private SSH key.

Note: When we create SSH keys using puttygen.exe, it will create a key pair (public & private). the public key is used while creating the instance and the private key is used here while connecting to the instance.

3) Now you are successfully connected to your instance.

Steps To Access Windows Instance

If you have created a Windows instance than it will generate a public IP, username, and password which we will use to connect to the instance using Remote Desktop Connection (RDC).

1) Creating a Windows Instance.

2) Connecting a Windows instance

3) You need to reset the password for once.

Note: You need to open 3389 port in the security list for connecting to windows instance.

Note: When we terminate an instance the changes done on Instances Local drive are lost but the saved changes to the attached volume retained.

Error While Connecting To Instance

You can get error while connecting to the created instances due to various reasons like open appropriate port, SSH key issue, forgot to add private key and more.

If you are getting these errors while connecting to the instance than refer our post at http://k21academy.com/oci45

Important Concepts Related To Compute

1) Instance Console Connection: Used when we do not have a private SSH key of an instance or we lost it by mistake. The process is to create a new instance with new SSH key pairs(public & Private). And using that instance we can update the public SSH key of the initial instance.

To know more about Instance Console Connection click here.

2) Custom Images: We create an image of the instance in Object Storage and use that image to create similar configuration instances. We can edit configuration if we want while creating the instance.

3) Block Volumes: It is attached to compute instances for storage. It consists of a Boot and block volume. Boot volume is like a Boot disk in which OS data is stored and Block volume is used for regulatory data storage.

4) Autoscaling: It allows us to activate or deactivate compute instances depending on the requirements in an Instance pool. We can increase and decrease the number of instances using autoscaling.

To know more about Autoscaling in OCI click here

5) Resizing of Instance: Rather than creating a new Compute instance for a higher workload, we can resize the existing instance up and down.

To know more about Resizing of Instances click here http://k21academy.com/oci58

6) Instance Configuration & Instance pool: Instance Configuration is used to set a template of OS image, metadata, storage, VNIC, subnets, and use this configuration multiple times to create similar types of instances. Instance Pool is a set of similar type of instances created using instance configuration.

To know in detail about Instance Configuration & Instance Pool click here http://k21academy.com/oci23

7) High Availability: We can deploy instances across various Fault Domain (FD), Availability Domain (AD) & Regions to make it highly available. It also helps in protecting instances against FD, AD, or region failure.

To know in detail about Regions, AD, FD & High availability click here https://k21academy.com/oci27

The post Compute In Oracle Cloud (OCI) – VM, BM & Dedicated VM Host appeared first on Oracle Trainings.

The term cloud-native gets thrown around a lot, especially by cloud providers. If you have ever had an experience in cloud computing,  you probably have come across the word cloud-native at least once.

• But what exactly does cloud-native mean?
• How it differs from the concept of the traditional approach?
• And, why it is so important?

In this post, we will discuss the term cloud-native in more detail and cover several key features of cloud-native applications.

Cloud-native applications refer to the apps that are based on microservices and there will be a huge demand for microservices-based architectures in the future.

IDC researchers predict, by 2022, it is estimated that 90% of all new apps will feature microservices architectures that improve the ability to design, debug, update, and leverage third-party code; 35% of all production apps will be cloud-native.

So, now that we know the future belongs to cloud-native applications, let us first look at the definition of cloud-native.

What Is Cloud-Native?

Essentially, the gist of Cloud Native is that applications should be built in the cloud, for the cloud, maximizing the advantages of the cloud. Let’s discuss it more

• Cloud-native is an approach of building and running applications that exploits the benefits of the cloud computing delivery model.
• Moving something in the cloud is not cloud-native
• Applications running in the cloud are not necessarily cloud-native.
• Cloud-native is about how applications are created and deployed, not where.
• In fact, an application running on-premises or a private cloud may still be cloud-native if it meets certain sets of properties and standards.

Key Objectives Of Cloud-Native

Let’s discuss three key objectives that define Cloud-Native:

1. Capitalize on the Cloud: adopt a Cloud-First strategy, that is, look for capabilities that are already available in the cloud and use the greatest value services that suit your needs and only bring into the cloud what the cloud doesn’t offer.
2. Deliver value early and often: rapid, agile software delivery, that is, break long release cycles into smaller, incremental releases, and also support CI/CD(continuous integration/continuous delivery) pipeline
3. Build applications to exploit the cloud: different than building applications that run within the cloud, that is, building applications that can
   • deploy easily and quickly
   • Deploy to secure operating environments with resource isolation
   • Scale in and out as needed
   • Achieve high-performance characteristics
   • Support high availability requirements
   • Integrate easily and securely across cloud and on-premises environments
   • Minimize cost, and so on.

Characteristics Of Cloud-Native Technologies

Cloud-native applications can be extended across different environments such as

• private cloud,
• public cloud,
• on-prem,
• or a combination of these like hybrid clouds.

Cloud-native technologies are characterized by:

1. Containers: A standard unit of software that packages up code and all its dependencies therefore the application runs quickly and reliably from one computing environment to another.
2. Microservices: A collection of services that are very loosely coupled, independently deployable, only communicate through APIs, and are less complex and thus smaller as they generally focus only on a single functionality.
3. Serverless Functions: Functions as a Service (FaaS), or hosted serverless that utilizes Docker containers for execution.
4. Development Pipelines: A CI/CD pipeline helps you automate steps in your software delivery process, like initiating code builds, running automated tests, and deploying to a staging or production environment.
5. Infrastructure-as-Code: Software that defines service instance creation, e.g. the “recipe” or
   the manifest can be managed the same way development teams manage the source code for their projects.
6. Event-Driven Application: Oracle Events Service eliminates the complexity of manually tracking changes across your cloud resources and responding to them in near real-time with Functions, Notifications, and Streaming.
7. Application Programming Interfaces (APIs): API Gateway when used with Oracle Functions, you can create RESTful APIs that are serverless. No need to provision compute resources anymore, just develop your function and deploy as an API.

Benefits Of being Cloud-Native?

• Flexibility: Lets you deploy, repeat, and redeploy resources fast and easily, whenever and as long as necessary.
• Automatic: A definite proportion of automation is needed to produce output faster. It reduces our effort in testing and delivering the product.
• Efficiency: The applications developed using cloud-native technologies are 13 times more efficient than applications build using non-cloud native technologies.
• Testability: CI/CD (Continuous Integration/Continuous Delivery) approach helps establish an automated way to test applications and deploy them as soon as the code is built.
• Disposability: Supports the disposable process that starts up soon and shuts down gracefully providing maximum robustness and quick recovery from unexpected crashes.

Cloud-Native vs Traditional Approach

1. Traditional- OS-dependent, Cloud Native- OS independent/ OS abstraction: The traditional infrastructure allows us to build close dependencies between the app and the OS. This dependency makes the application migration process complex and risky.

   The cloud-native infrastructure lets the developers abstract away from infrastructure dependency which allows the teams to focus on their software entirely.

2. Traditional- Unpredictable, Cloud Native- Predictable: Traditional infrastructure is predicated on a long-term development process. It takes a longer time to build and releases are done as one big package.

   On the other hand, a cloud-native infrastructure is designed to maximize the resiliency through predictable behaviors to enable new business functions.

3. Traditional- Over-sized capacity, Cloud Native- Right-sized capacity: The traditional infrastructures are over-sized that lack the capability to scale beyond, delaying the deployment of an application.

   The cloud-native infrastructure allocates the resources based on the ongoing requirement of the application. This approach optimizes app lifecycle management.

4. Traditional- Manual, Cloud Native- Automated: Traditional development process requires heavy in-house administration as they are manually operated, which can be time-consuming and expensive for your business.

   Cloud-native infrastructure is automated in nature that consistently applies the same set of rules in the process across any size of deployment.

Conclusion

With the advent of cloud-native, the code complexities have been simplified, making it easy for developers to develop a better application. The journey to cloud-native can be a long road, but you’ll find it rewarding in the end.

Oracle lets you migrate your data from On-premise to OCI using data transfer service. You can also export data from OCI to your data centers. With Data Transfer Service you can copy your data to a hard disk you own or an oracle supplied data transfer appliance to migrate data quickly and securely from on-premise to Oracle Cloud Infrastructure Object storage.

In this blog post, we are going to cover:

• Overview of Data Transfer Service
• Core Components of Data Transfer Service
• How to Upload the Data
• Is your Data Safe?
• How to Navigate to Data Transfer Service
• Tracking the Status of Transfer Package
• Storage Gateway

If you wish to know more about Migration, visit https://k21academy.com/ebscloud15 or check out our Free Masterclass on Migrate EBS (R12) To Cloud With Almost Zero Downtime by visiting https://k21academy.com/ebscloud10

Overview Of Data Transfer Service

Data Migration Service lets you securely move petabytes-scale datasets from the customer’s data center to Object/Archive Storage on OCI. Moving data over the public Internet is not always the smart choice due to various reasons like long transfer times, high network costs, unreliable network connectivity and a very important aspect which is security.

Note: Data Transfer in NOT available in OCI Government Cloud Regions. The only regions that it is available in are Pheonix, Ashburn, London and Ashburn.

Data can be transferred in both modes Offline and Online. Online Data is transferred through Storage Gateway and Offline data is transferred through Data Transfer Service.

Online Data transfer can take a very long time depending upon the internet bandwidth so it is always advised to use offline mode using data transfer service for a large amount of data.

Data can be transferred using two types of transfers named Appliance-Based Data Transfer and Disk-Based Data Transfer.

Appliance-Based Data Transfer

Oracle sends you a secure, high-capacity storage appliance through which you send your data to the Oracle transfer site. Employees at Oracle will then upload the data into your designated Object Storage bucket in your tenancy. You do not need to purchase any hardware for the transfer as Oracle supplies both the hardware and the software required to manage the transfer.

Data Transfer Appliance (DTA)

• Customer rents one or more DTA from Oracle, loads data and sends to Data Transfer site.
• Upto 150 TB
• Data Encrypted (AES-256) before transit Data uploaded, verified, erased from DTA.

Disk-Based Data Transfer

You can transfer your data by storing your data on an encrypted disk and sending it to the Oracle transfer site. Oracle will upload your data into your designated Object Storage bucket in your tenancy. The disk will be yours and will be transferred back to you after the data transfer.

Data Transfer Disk

• Customer purchases Hard Disk on their own and is shipped back to the client after migration.
• Upto 100 TB and 10 disks per Transfer Packet.
• Data Encrypted (AES-256) before transit.
• Data uploaded to the bucket, verified, then erased from disk(s) and returned to the customer.

Oracle also lets you export your data using appliance-based Data Export. In this, you can export your data from your OCI Object Storage to your data center by using an Oracle-provided appliance. This is very useful when you want to share your data with a client or business partner.

Components Of Data Transfer Service

Data Transfer Disk and Data Transfer Appliance both have different core components. We will discuss both in detail below:

Data Transfer Disk: Components

Data Transfer Disk has 3 Components:

1. Transfer Job
2. Transfer Device
3. Transfer Package

Transfer Job: A transfer job represents the data set that you wish to upload to OCI. To use the data transfer disk service, we first need to create a Transfer job from the OCI console. We need to specify whether to choose Object Storage or Archive Storage.

Transfer Device: It consists of your hard disk drives, specially prepared to copy and upload data to oracle cloud infrastructure. You can copy your data into 1 or more of these devices and ship it to Oracle for the upload.
The drive can be an internal SATA II/III 2.5″ or 3.5″ drive or an external USB 2.0/3.0 drive.

Transfer Package: A transfer package represents the parcel to help ensure the upload is done in once continuous operation across multiple disks. Each transfer package can contain up to 10 transfer devices.

Data Transfer Appliance: Components

Data Transfer Appliance has 2 components:

1. Transfer Job
2. Transfer Appliance.

Transfer Job: Just like in data transfer disk, here also we need to create a Transfer job from the OIC console and we need to specify whether we need our data to be stored in Object Storage or Archive Storage.

Transfer Appliance: It is a high capacity storage device, specially designed to copy and upload data to Oracle Cloud Infrastructure. You can copy your data to 1 or more appliance and ship it to Oracle for the upload.

Note: Make sure you review the default Data Transfer Disk service limits to determine the number of transfer jobs, transfer packages, and transfer devices you can create in your tenancy. If you need more then the limit then you need to request a limit increase by reaching out Oracle support.

How To Upload The Data

If you have a tenancy in Oracle Cloud Infrastructure you are eligible for the data transfer. To use the Data Transfer Service, you need to follow the following 6 easy steps to upload the data.

Is My Data Safe During The Data Transfer?

Yes, your data is completely secured during the transfer. All data written to the Hard Drive or stored on the Transfer Appliance is encrypted using AES-256 cipher Encryption.

For Data Transfer Disk, the Encryption keys are stored in a separate safe location from the hard drives so even if the hard drives are lost or intercepted while being shipped the data on the hard drive can never be accessed. Once the data transfer is complete, Oracle wipes the data and ships your hard drives back to you.

For Data Transfer Appliance, the Encryption password is stored securely in Oracle Cloud Infrastructure separate from the transfer appliance so if the appliance is lost or intercepted while being shipped the data on the appliance can never be accessed.

How To Navigate To Data Transfer Service

Data Transfer Service is available in OCI console under Object Storage. Using the Import and Export you can easily migrate your data from on-premise to cloud and vice-versa.

Data Transfer – Import: When you want to import your data from your on-premise to oracle cloud infrastructure, you use Import.

Data Transfer – Export: When you want to export your data from your tenancy to your on-premise, you use Export.

Tracking The Status Of Transfer Package and Transfer Devices

You can check the status of Transfer Package in 2 ways:

1. Oracle Cloud Infrastructure service console
2. Data Transfer Utility

Storage Gateway

• Storage Gateway supports you to connect the on-premise application to object storage in Oracle Cloud Infrastructure.
• Applications which can write data to an NFS target can also write data to the Oracle Cloud Infrastructure Object Storage, without requiring application modification to uptake the REST APIs.

This blogpost covers, Azure Cost Savings Tips in which we will discuss about 14 best practices that help reduce Azure costs and study tools that gives you needed visibility on how much you are spending, these tips will help you to make the most of your money with Azure cloud.

It is a part of our Microsoft Azure Administrator Training [AZ-104] in which the Attendees got this topic as their assignment and Radha (Attendee) performed excellently with the task and came up with this blog:

Many organizations are moving additional resources to the cloud, and cloud costs are becoming a large part of IT budgets. The cost of a cloud-based storage solution like Microsoft Azure is based on usage. However, if not properly managed, costs in Azure can easily spiral out of control.

Here are the top 14 best practices for cost management in Azure:

1. Reserved Instance:

Azure Reserved Instances are the VMs that have been reserved on Microsoft Azure Public IAAS Cloud for dedicated use on 1 year or 3 years basis.

• 1-year reserved instance—requires paying for one year upfront, grants a 40-45% discount for most virtual machines
• 3-year reserved instance—requires paying for three years upfront, grants a 60-65% discount for most virtual machines

See reserved pricing details for all VM types and managed services

2. Azure Hybrid Benefit:

Azure Hybrid Benefit is a program that leverages Microsoft’s extensive enterprise install base. If you already have licenses of Windows Server or SQL Server and you are using them on-premises, you can bring those licenses with you to the cloud.

Azure VM costs take into account a cost for Microsoft software licenses, so if you already have a license, you can receive discounts on VM costs and you can also use existing licenses to receive discounts on Windows Server VMs, SQL Server VMs, and the managed SQL Database service. Combining reserved instances with the hybrid benefit program can result in discounts of up to 80%.

3. Shutdown VMs:

VMs are only charged when they are running. If we have a test or development servers that don’t need to be on 24*7, schedule them to shut down when not in use.

4. Naming Standards:

Well-designed naming standards enable you to identify resources in the portal, on a bill, and within scripts. It facilitates more efficient management of the environment at all levels.

5. Azure Policies:

Azure Policy is another capability in the Azure platform where an enterprise can create various policies and then deploy them at an appropriate scope such as a subscription or a resource group. To know more about Azure Policy.

6. Right-Sizing and Right VM Series:

When provisioning VMs for various application workloads it is worth spending time and effort on finding the correct metrics that the application under load generates. A right-sized VM and right VM also has the advantage of not having to constantly change it.

Remember that you achieve optimal cost when all VMs are utilized at 100%. Try to get as close as possible to this goal by monitoring your metrics using Azure Monitor, and use auto-scaling or other methods to add and remove machines according to utilization

7. Region:

Azure resource prices can depend on operational costs and other factors in the specific region, if there is no need to deploy them within a particular region, you can run your VMs in the cheapest available regions to reduce the cost for your Azure virtual machines.

To know more about the region, availability set, availability zone click here.

8. Storage:

Azure provides different types of storage capabilities from a replication perspective. An easy method to reduce the storage costs is to delete the unused, unattached disks, that remain in the storage.

Also, find out which disks are taking maximum disk storage and thereby modify it to gain potential cost reduction.

You may also have unmanaged disks in Azure—search for these using the Disks (classic) screen. If you find an unmanaged disk that is not attached to any VM, follow these instructions to delete it by running a script.

9. Azure Advisor:

Advisor is a personalized cloud consultant that helps to follow best practices to optimize Azure deployments. It analyzes resource configuration and usage telemetry and then recommends solutions that can help us improve the cost-effectiveness, performance, high availability, and security of your Azure resources.

10. Spot Instance:

With Azure Spot Virtual Machines (Spot VMs), we’ll be able to access unused Azure compute capacity at deep discounts, up to 90 percent compared to pay-as-you-go prices. Spot VMs are ideal for workloads that can be interrupted, providing scalability while reducing costs.

11. Pricing calculator:

Configure and estimate the costs for Azure products and features for specific scenarios. To check the pricing of various resources click here

12. Free Services:

Azure provides Free services for the Free Account for 12 months utilize that and keep learning (not recommended for critical production Environment).

13. Dev/Test Labs:

It helps developers and testers quickly create environments in Azure and deploy and test their applications. Easily provision Windows/Linux machines in labs using reusable templates and artifacts while minimizing waste and controlling cost.

14. Windows Virtual Desktop:

It is a desktop and app virtualization service that is virtualized and runs in Azure. Basically, it includes Office 365 ProPlus and can be spun up with a consumption-based model that can be absolutely perfect for MSPs. It allows you to bring our own OS image and also run as many customized desktop pools as we need to accommodate our customers.

We could potentially have a generalized customer pool for those that need a basic desktop, or we could also give each customer their own dedicated pools within your Azure tenant or within their own! we also have the ability to provide a more traditional RDSH (Remote Desktop Session Host) experience with this feature in Azure as well for more flexibility for generalized workloads.

As for cost Optimization, we must have an eligible Windows or Microsoft 365 license. Since many of your customers will likely have this already.
We must pay for the ongoing VM compute cost and associated storage consumed by the desktops.

In this blog, we are going to cover the Docker Networking overview, different types of networking i.e bridge networking, host networking, overlay networking, and Macvlan networking.

Note: Docker Networking and its type is part of Docker & Kubernetes to know more about the Docker & Kubernetes Overview click here

Note: To know more about the Certified Kubernetes Administrator certificate exam topics click here and to know more about the activity guides/hands-on lab exercise you should perform to clear the certification exam click here

Networking In Docker Overview

Networking in Docker is to connect the docker container to each other and outside world so they can communicate with each other also they can talk to Docker Host. you can connect docker containers to non-Docker workloads. Docker uses CNM Container Network Model for networking. This model standardizes the steps required to provide networking for containers using multiple network drivers.

Bridge Networking

Bridge network is a default network created automatically when you deploy a container. Bridge network uses a software bridge that allows containers connected to the same bridge network to communicate. Bridge networks used on containers that are running on the same Docker daemon host. The bridge network creates a private internal isolated network to the host so containers on this network can communicate.

Host Networking 

This takes out any network isolation between the docker host and the docker containers. Host mode networking can be useful to optimize performance. It does not require network address translation (NAT).

Note: The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

Overlay Networking 

Overlay networking is used if container on node A wants to talk to node B then to make communication between them we use Overlay networking. Overlay networking uses VXLAN to create an Overlay network. This has the advantage of providing maximum portability across various cloud and on-premises networks. By default, the Overlay network is encrypted with the AES algorithm.

Macvlan Networking 

Macvlan network is used to connect applications directly to the physical network. By using the macvlan network driver to assign a MAC address to each container, also allow having full TCP/Ip stack. Then, the Docker daemon routes traffic to containers by their MAC addresses. You can isolate your macvlan networks using different physical network interfaces. This is used in legacy applications which require MAC address.

The post Oracle Integration Cloud (OIC) ADW/ATP Adapter appeared first on Oracle Trainings.

We have been getting lots of queries from our trainees on how to use Notification Activity in OIC.
In this blog, we are going to show you how to use Notification Activity in the Oracle Integration Cloud. It particularly useful when you want to be notified when an error has occurred in integration.

If you are new to Oracle Integration Cloud (OIC), then check out our blogs Oracle Integration Cloud (OIC) For Beginners Overview

What Is Notification Activity

The Notification Activity is used to send an E-Mail notification to any number of recipients. You have the ability to select the From address and to create a custom email body and have the field that you need in the notification.

OIC gives the flexibility to choose the sender for these notifications. This can be achieved by adding a list of email addresses that can later be approved to qualify as an Approved Sender in OIC.
You also have an option to select attachment with the notification E-Mail, this is useful as it saves time as you no longer have to create a Microsoft Email adapter to handle attachment.

How To Use Notification Activity

Notification Activity can be used directly in the Integration also if you want to be notified when a fault occurs you can add notification activity in the global fault handler.

Inside the Global Faults, you have the ability to send notifications when a fault/error has occurred in an integration. In the notification activity, you can choose to send error code, cause of the error, and more.

Step By Step Guide To Send Error Notification

For the purpose of this blog, we are using an already created integration to insert data into DB.

1.  Click on Global Fault. You can apply any business rule, invoke external service, send an email notification, etc.

2.Enter Name and optionally Description for the notification.

3. The notification configuration window will get open as shown in the below screenshot.

4. Click the edit icon in front of From option. This allows you to enter from the address.

5. Enter From address “ics.notifier@oracle.com” or “no-reply@oracle.com” in the expression input box. Click Validate then Close button from the right upper corner.

6. Similarly, we can configure To address. Enter To addresses in the case to send the notification to one or multiple recipients.

7. Similarly, we can configure the Subject. Enter a comma-separated subject in the case to send the notification to multiple recipients.

8. The body can be plain text and HTML. Curly braces are used to {}  send any parameter value with the body.

9. In the body enter a below Message or create your own that you would like to be notified with.

Hi Harshit

Unable to inserting user in DB
ID: {ID}
Name:{NAME}

Error: {ERROR}
Cause: {CAUSE}

10. Parameters can be created with the table given under the Body input text. Click + sign to create any variable.

11. Enter Parameter name as ID and click the edit icon to assign any value to it.

12. Drag and drop id from source to expression box then click on validate then close.

13. Click + sign to create another variable. Change Parameter name to NAME and click on edit in the parameter value.

14. Drag and drop FIRSTNAME from source to expression box then click on validate then close.

15. Click + sign to create another variable. Change Parameter name to ERROR and click on edit in the parameter value.

16. Drag and drop error code from source to expression box then click on validate then close.

17. Click + sign to create another variable. Change Parameter name to CAUSE and click on edit in parameter value.

18. Drag and drop reason from source to expression box then click on validate then close.

19. Click on Validate and then click on save.

20. This is how you configure Notification Activity to shoot when an error has occurred.
21. If an error is encountered you will get a mail with all the parameter values defined earlier.

I hope this blog was able to guide you on how to use notification activity to inform when an error has occurred.

One of the biggest benefits of cloud computing is that it can be elastic. Like a rubber band, the idea behind elastic computing is that you can stretch or shrink your cloud service usage to accommodate changes in workload.

Azure includes several services with elastic features. One of the newest, and least understood, is Azure Virtual Machine Scale Sets.

What Are Virtual Machine Scale Sets (VMSS)?

Virtual Machine Scale Set, an interesting service offered by Microsoft Azure, helps to create and manage a set of identical, auto-scaling Virtual Machines (VMs). The number of VM instances can automatically increase or decrease based on scheduled conditions.

Auto-Scaling

Auto-scaling is a way to automatically scale up or down the number of compute resources that are being allocated to your application based on its needs at any given time.

The key point is that you can now design a scalable architecture that will automatically scale-up or scale-down to meet your needs over the lifetime of your setup regardless of how fast/slow or big/small your site grows over that time.

Here are the most popular ways of autoscaling:

• Horizontal Scaling
• Vertical Scaling

Vertical Scaling:

Vertical Scaling is an attempt to increase or decrease the capacity of a single machine, also called scaling up or down. Here the resources such as processing power, storage, memory, and more are added to an existing work unit.

It is done to increase the capacity of existing hardware or software by adding resources. It can enhance your server without manipulating your code. But it is limited by the fact that you can only get as big as the size of the server.

For example, you could move an application to a larger VM size.

Horizontal Scaling:

Horizontal Scaling is a must use technology – whenever a high availability of (server) services are required, also called scaling out and in, means adding or removing instances of a resource. Scaling horizontally involves adding more processing units or physical machines to your server or database.

It involves growing the number of nodes in the cluster, the application continues running without interruption as new resources are provisioned.

If demand drops, the additional resources can be shut down cleanly and deallocated.

In Autoscaling you have to specify a minimum and the maximum number of instances to run and add or remove VMs automatically based on a set of rules.

When rule conditions are met, one or more autoscale actions are triggered. You can add and remove VMs, or perform other actions.

Autoscale Settings

An autoscale setting is read by the autoscale engine to determine whether to scale up or down.

You can create custom autoscaling rules as needed for your situation. Rule types include:

• Minimum Instance: The minimum number of instances you want to deploy in your scale set.
• Maximum Instances: The maximum number of instances you want to deploy while scaling out. (Note: In Azure, you can have maximum, 1000 instances)
• Metric-based – It measures application load and add or remove VMs based on that load. For example, add instance in scale set when CPU usage is above 50%.
• Time-based – For example, trigger an instance every 8 am on Saturday in a given time zone.

Here are a few points which are important when we think about going with Horizontal scaling or Vertical Scaling.

• Scaling up requires downtime, in this case, you need to upgrade server’s configuration like RAM, memory, CPU, etc. so while upgrading this configuration your server requires downtime. Once you are done with the update, the restart of the server is required.
• Scaling up will Increase performance but not available because its only one instance and it can go down anytime when it reaches out the scaling rules.
• Scale-Out doesn’t require downtime, in Scale-out its creates new instances of server it doesn’t touch the existing instance, so no downtime required.
• Scale-Out, Increase performance and availability as well. When autoscaling increase no. of instances and handle load/request using load balancer it increases the performance of the server and also increases availability as well.

Difference Between Virtual Machine & Container (Docker)

The major difference between the VMs and Container is In VMs a hypervisor is used to virtualize physical hardware. Each VM contains a guest OS, a virtual copy of the hardware that the OS requires to run while in Containers Instead of virtualizing the underlying hardware, containers virtualize the operating system so each container contains only the application and its libraries.

1) Operating System: In virtual machine has its guest OS above the host OS, which makes virtual machines heavy. While in multiple containers share the host OS, and that is why they are lightweight.

2) Security: VM does not share OS, and there is strong isolation in the host kernel. Hence, they are more secure as compared to Containers. A container has a lot of security risks, and vulnerabilities because the containers have a shared host kernel.

3) Performance: Containers are lightweight and consume fewer resources While VM is heavy and consumes more resources so containers give better performance then VM.

4) Portability: Containers are easily portable because they do not have separate operating systems. While virtual machines have separate OS, so porting a virtual machine is very difficult.

Difference Between Physical Host vs Virtual Machine

A virtual machine (VM) is used as a copy of an actual physical computer. A virtual server operates in a multi-tenant environment, meaning that multiple VMs run on the same physical hardware. Physical server runs a single application, these generally provide applications and data for a single tenant. The resources and components of a physical server are not shared between multiple users.

1) Performance: Physical server also known as a bare-metal server. the performance of the bare-metal server is better than the virtual machine because physical host is dedicated to a single host/application while in VM multiple application uses the same resources.

2) Cost: Building and maintaining a physical server environment is very expensive because due to the constant hardware and software upgrades, frequent system failures. On the other hand, A virtual server environment allows you to distribute resources among all running VMs, thus ensuring capacity optimization for a minimal price.

3) Disaster Recovery and High-Availability: Virtual machines have a definite advantage when compared to running workloads on physical servers in terms of DR and HA. In a physical server, it is very hard and very costly to do disaster recovery while in VM we can easily perform DR via cloud vendor VM machine in different regions.

4) System Recovery: It is essential to quickly restore mission-critical data and operations in case of any disaster so as to reduce system downtime. It can take several hours or days to restore applications running on a physical server. You can restore the entire VM at a DR site with the help of previously created VM backups, resulting in almost zero downtime.
