Module 1: Plan and Design solutions in Oracle Cloud Infrastructure:

1) OCI Cost Analysis, Budgets & Usage Reports

Billing and Cost Management is the service that you use to pay your Oracle services bill, monitor your usage, and budget your costs.

Note: All Billing and cost-related options are available under ‘Account Management’.

• OCI Cost analysis Visualization tools Help understand spending patterns at a glance.
• OCI Budgets can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when we might exceed our budget.
• OCI Usage Reports is a breakdown of the consumptions of your Oracle Cloud Infrastructure resources such as the compute, networking, storage, etc.

2) Instance Configuration & pools

1. Instance Configuration helps you to save the configuration (such as Network Configuration, OS, VM Shapes, attached block volume) of your compute instance which is already running.
2. Instance Pools helps you to create single or multiple Compute instances (Machines) in one go of the same configuration using Instance Configuration.

3) Autoscaling Configurations

Autoscaling enables you to automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU or Memory utilization.

4) Instance Console Connection

Instance Console Connection provides console connections that enable you to remotely troubleshoot malfunctioning instances, such as:

• An imported or customized image that does not complete a successful boot.
• A previously working instance that stops responding.

5) Create Custom Images

• Create a custom image of an instance’s boot disk and use it to launch other instances
• Instances you launch from your custom image include customizations, configuration, and software installed when you created the image

Module 2: Design, Implement and Operate Databases in OCI:

1) Enabling Data Guard on VMDB system

Data Guard and Active Data Guard provide disaster recovery (DR) for databases with recovery time objectives (RTO) that cannot be met by restoring from backup.

This Hands-On guide includes the steps to enable Data guard on a VMDB system.

2) Data Guard creation, Switch Over, Failover, Reinstate

• Data Guard creation: It consists of the steps to create data guard for VM/BM
• Switch Over: 
  • A switchover reverses the primary and standby database roles.
  • Each database continues to participate in the Data Guard Association in its new role.
  • A switchover ensures no data loss.
• Failover: 
  • A failover transitions the standby database into the primary role after the existing primary database fails or becomes unreachable.
  • A failover might result in some data loss.
• Reinstate:
  • You can use the reinstate command to return a failed database into service after correcting the cause of failure.

Module 3: Migrate on-premises workloads to OCI:

1) Zero Downtime Migration

• Zero Downtime Migration (ZDM) is a software solution that allows you to directly and seamlessly migrate your on-premises Oracle Databases to the Oracle Cloud whether in OCI or ExaCC.
• It ensures that there is minimal to no production database impact during the migration.

2) Move to Autonomous database(ADB)

• Deliver automated patching, upgrades, and tuning—including performing all routine database maintenance tasks while the system is running—without human intervention.
• The autonomous database cloud is self-driving, self-securing, and self-repairing.
• Autonomous Database is fully elastic means at any time, you may scale, increase or decrease either the OCPUs or the storage capacity.

3) Database CLI

• The database CLI (dbcli) is a command-line interface available on bare metal and virtual machine DB systems.
• After you connect to the DB system, you can use the database CLI to perform tasks such as creating Oracle database homes and databases.

4) Install & Configure Storage Gateway in OCI

• Storage Gateway is a cloud storage gateway that lets you connect your on-premises applications with Oracle Cloud Infrastructure.
• Applications can interact with Oracle Cloud Infrastructure Object storage through standard NFSv4 protocols.
• This Hands-On Guide covers steps to install and configure storage gateway in OCI

Module 4: Implement and Operate solutions in OCI:

1) Creating an Oracle Support Service Request

Some of the tasks you might typically perform yourself in an on-premise data center must be performed by Oracle Support. For example, you must file a Service Request (SR) so Oracle Support can perform the following actions for you:

• Set up a secure VPN connection from your data center to the Model 300 service.
• Set up NAT routing for public IP addresses.
• Recover or reinstall instances.

2) Checking Limits, Quotas, and Usage in OCI

• Service Limit is the quota or allowance set on a resource. For example, your tenancy is allowed a maximum number of compute instances per availability domain.
• A Usage Report is a comma-separated value (CSV) file that can be used to get a detailed breakdown of resources in Oracle Cloud Infrastructure for audit or invoice reconciliation.
• Compartment Quotas are similar to service limits; the biggest difference is that service limits are set by Oracle, and compartment quotas are set by administrators

Module 5: Design for Hybrid cloud architecture:

1) VCN Peering (Local & Remote)

• Enables connectivity between the resources in different VCNs
• Does not require public IPs or NAT to enable connectivity
• Traffic never leaves the Oracle Network
• Over other options such as connecting over the internet, VCN Peering offers
  • Faster connectivity
  • Higher security
• Two types of VCN peering (Local & Remote)

2) Configure Virtual Firewall in OCI

• Although Oracle Cloud Infrastructure includes firewall capabilities, some customers prefer to run their own custom firewalls.
• The benefits of configuring a virtual firewall in OCI are antivirus, web filtering, and antispam.
• This Hands-On Guide covers the process of configuring the different virtual firewalls in OCI.

3) SSL Handling by OCI Load Balancer(LB)

• SSL (Secure Sockets Layer) is an industry-standard protocol for securing network connections. SSL provides authentication, encryption, and data integrity using public key infrastructure (PKI).
• To use SSL with your load balancer, you must add one or more certificate bundles to your system.
• SSL Termination – SSL is terminated at LB. LB can accept encrypted traffic from a client; no encryption of traffic between LB and backend servers
• SSL Tunneling – SSL implemented between LB and backend servers
• End to end SSL – LB can accept SSL encrypted traffic from clients and encrypts traffic to the backend servers

4) DNS Zone Management

• Highly scalable, global anycast Domain Name System (DNS) network that assures high site availability and low latency.
• Offers a complete set of functions for zone management:
  • Create and manage zones and records
  • Import/upload zone files
  • Filter and sort views of zones and records
  • Secondary DNS support
  • APIs and SDKs

5) Creating Health Checks

• The Oracle Cloud Infrastructure Health Checks service provides users with high-frequency external monitoring to determine the availability and performance of any publicly facing service, including hosted websites, API endpoints, or externally facing load balancers.
• Health Checks Service Components
  • Monitors: Monitors allow you to continuously monitor the health of public-facing endpoints.
  • On-demand probes: It allows you to execute a one-time probe to assess the health of a public-facing endpoint.
  • Vantage points: These are geographic locations from which monitors and probes can be executed to your specified target.
  • Protocols: The Health Checks service allows you to configure both HTTP and ping type monitors. Each type has respective protocols.

Module 6: Design for Security and Compliance:

1) Web Application Firewall(WAF) Concepts and Use Cases

• Web Application Firewall (WAF) refers to a device, server-side plugin, or filter that applies a set of rules to HTTP/S traffic
• By intercepting HTTP/S traffic and passing them through a set of filters and rules, WAF is able to uncover and protect against attack streams hitting a web application.

2) Instance Principals and Dynamic Groups

• Instance Principals lets instances (and applications) to make API calls against other OCI services removing the need to configure user credentials or a configuration file.
• Dynamic groups allow you to group Oracle Cloud Infrastructure compute instances as “principal” actors (similar to user groups).

3) How to enable MFA (Multi-factor Authentication)

• Multi-factor authentication (MFA) is a method of authentication that requires the use of more than one factor to verify a user’s identity.
• Examples of authentication factors are a password (something you know) and a device (something you have).

4) Federating OCI with Oracle Identity Cloud Service (IDCS)

Oracle Identity Cloud Service is the identity provider for multiple Oracle services. Federating Oracle Cloud Infrastructure with Oracle Identity Cloud Service allows you to have a seamless connection between services, without having to create a separate username and password for each one.
