In this blog, I am going to share some quick tips, including Q/A and useful links from Day 1 of previously launched Azure Fundamentals [AZ900] training. Covering Module 1: Cloud Concepts and Module 2: Core Azure Services, where we discussed topics like Cloud Overview, Cloud Service Models, Azure Cloud Overview, Azure Subscriptions, Resource groups, Azure Resource Manager, Azure Regions, Virtual Machines, Virtual Networks, Storage Services, Database Services.
We also covered hands-on Lab 1, Lab 2, Lab 4, Lab 5, and Lab 6 out of our extensive 20+ hands-on labs.
So, here are some of the Q/As asked during the Live session.
Cloud computing
Cloud computing is on-demand access, via the internet, to computing resources like applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities.
Companies that provide cloud services enable users to store files and applications on remote servers and access the data via the Internet. This means the user is not required to be in a specific place to gain access, allowing the user to work remotely.
Cloud Deployment Models
The cloud deployments models represent a specific type of cloud environment, primarily distinguished by ownership, size, and access, and also describes the nature and purpose of the cloud. Cloud deployment models are categorized as public clouds, private clouds, and hybrid clouds.
Check more on Cloud Deployment Models.
Public Cloud
The public cloud is open to all to store and access information via the Internet using the pay-per-usage method. In the public cloud, computing resources are managed and operated by the Cloud Service Provider (CSP).
Examples of CSPs are Microsoft Azure, Google Cloud Platform, Amazon Web services, Oracle Cloud, etc.
Private Cloud
A private cloud is well known as an internal cloud or corporate cloud. It is offered to selected users over the internet or a private internal network. It provides greater security controls. It can be deployed using Opensource tools such as Openstack and Eucalyptus.
Hybrid Cloud
Hybrid Cloud is an example of both public and private cloud. It shares securities responsibilities. It helps to maintain the strongest controls over sensitive data and processes.
Example– Azure stack hub is an extension of Azure that provides a way to run apps in an on-premise environment and deliver services on your data center.
Q1. What is the difference between on-premises and private cloud?
Ans. On-premises computing has all resources located on-site, that is, at the same location where it is accessed and used.
In a private cloud, the resources are in an offshore location and can be accessed by the concerned organization and its employees as per need. However, in both cases, the resources are for just one organization, and there is no sharing with anyone else.
Cloud Services Model
Cloud computing offers different services based on three delivery models. They follow the order of SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a service).
These are three main types of cloud computing services, sometimes called the cloud computing stack, because they build on top of one another.
Microsoft Azure
Microsoft Azure, commonly referred to as Azure, is a cloud computing service created by Microsoft for building, testing, deploying, and managing applications and services through Microsoft-managed data centers.
It provides software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS) and supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software and systems.
Q2. How does Microsoft Azure work?
Ans: Once customers subscribe to Azure, they have access to all the services included in the Azure portal. Subscribers can use these services to create cloud-based resources, such as virtual machines and databases.
Accounts and Subscriptions
An Azure account is a globally unique entity that gets you access Azure and your Azure subscriptions. You can create multiple subscriptions in your Azure account to create separation, for example – for billing and management purposes.
Q3. What is an Azure free-trial account?
Ans. Azure free account is one way to access Azure services. When you start using Azure with a free account, you get USD200* credit to spend in the first 30 days after you sign up.
In addition, you get free monthly amounts of two groups of services: Popular services, which are free for 12 months, and 25+ other services that are free always. Free services are based on resource and region availability.

Resource Groups
A resource group is a logical container that holds related resources for an Azure solution. It helps in managing all the resources in a group. It helps us to allocate resources to a resource group. Generally, it adds resources that share the same lifecycle to the same resources group so you can easily deploy, update, and delete them as a group.
Check more on Resource Groups.
Q4. What are the Maximum numbers of resource groups per subscription?
Ans. The maximum number of Resource groups per subscription is 980.
Check more on Subscription Limits.
Q5. Can we create a resource group under another resource group?
Ans. No, we cannot create a resource group under another resource group as we have to follow the hierarchy/levels of the scope defined by Microsoft.
Check more on Azure level of scope.
Azure Resource Manager
Azure Resource Manager is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure account. You use management features, like access control, locks, and tags, to secure and organize your resources after deployment.
Check more on Azure Resource Manager.
Azure Regions
The Azure region is a set of data centers deployed within a latency-defined perimeter and connected via an underlying dedicated regional low-latency network. There are currently 50+ regions available worldwide, with another 12 additional Azure regions planned for the future.
Check more on Azure Regions.
Q6. Why are regions important?
Ans. Azure has more global regions than any other cloud provider. These regions give you the flexibility to bring applications closer to your users no matter where they are. Global regions provide better scalability and redundancy.
Azure Availability Zones
Availability zones are physically separate data centers within an Azure region. Each availability zone comprises one or more data centers equipped with independent power, cooling, and networking. An availability zone is set up to be an isolation boundary. If one zone goes down, the other continues working.
Check more on Availability Zones.
Q7. For which type of failure an Azure availability zone can be used to protect access to Azure services?
Ans. Availability Zones is a high-availability offering that protects your applications and data from data center failures. Availability Zones are unique physical locations within an Azure region. Each zone comprises one or more data centers equipped with independent power, cooling, and networking.
Azure Compute Service
Azure offers several ways to host your application code. The term compute refers to the hosting model for the computing resources that your application runs on.
1. Azure Virtual Machine
A Virtual Machine (VM) is a computing service that performs most functions of a physical computer, actually behaving like a separate computer system.
Q8. Virtual Machine is PaaS or IaaS service model?
Ans. Virtual Machines is an IaaS (Infrastructure as a service) because, on a VM, you can manage what operation system runs and what software is installed. You are just renting a virtual machine then picking up the OS to run, application frameworks, and storage.

2. Azure Container Services
Azure Containers are a lightweight, virtualized environment that does not require operating system management and can respond to changes on demand.
- Azure Container Instances: a PaaS offering that runs a container in Azure without the need to manage a virtual machine or additional services.
- Azure Kubernetes Service: an orchestration service(The process of automating the tasks needed to manage connections and operations of workloads on private and public clouds) for containers with distributed architectures and large volumes of containers.
Azure Networking Services
- Azure Virtual Network (VNet) enables Azure resources to communicate with each other, the internet, and on-premises networks.
- Virtual Private Network Gateway (VPN) sends encrypted traffic between an Azure virtual network and an on-premises location over the public internet.
- Azure Express Route extends on-premises networks into Azure over a private connection facilitated by a connectivity provider.
Azure Virtual network
Azure Virtual Networking (VNet) is the fundamental building block for your private network in Azure.VNet enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks.
Check more on Virtual Networks.
Q9. Can I modify the Virtual network after I created them?
Ans. Yes, You can add, remove, and modify the CIDR(Classless inter-domain routing) blocks used by a Virtual Network even after its creation.
Azure Storage Services
- Container storage (blob) is optimized for storing massive amounts of unstructured data, such as text or binary data.
- Disk storage provides disks for virtual machines, applications, and other services to access and use.
- Azure Files sets up highly available network file shares that can be accessed using the Standard Server Message Block(SMB) protocol.
Check more on Azure Storage Services.
Q10. Can we have a Database in Azure storage?
Ans. Yes, Azure Table storage is a cloud-based NoSQL datastore you can store large amounts of structured, non-relational data. Azure Table offers a schemaless design, enabling you to store a collection of entities in one Table.
Azure has a different section of DAAS(Database as a service) service in the Azure portal. Because, In Storage, there is no way to store relational databases.
Azure Database Services
- Azure Cosmos Database is a globally distributed database service that elastically and independently scales throughput and storage.
- Azure SQL Database is a relational database as a service (DaaS) based on the latest stable version of the Microsoft SQL Server engine.
- Azure Database for MySQL is a fully managed MySQL database service for app developers.
- Azure Database for PostgreSQL is a relational database service based on the open-source Postgres database engine.
Q11: What are the Prerequisites to learn Azure?
Ans. There is very little technical knowledge needed for starting with Azure Cloud. Basic knowledge of Networking will be beneficial.
