Introduction to Azure
Microsoft's cloud platform β dominant in the enterprise, and a valuable second cloud to know.
Microsoft Azure is the second-largest cloud platform and the dominant choice in large enterprises β especially those already using Microsoft products like Windows Server, Active Directory, and Office 365. Knowing both AWS and Azure makes you far more employable as a DevOps engineer.
π― Learning Objectives
By the end of this lesson you will:
- Understand what Azure is and where itβs used
- Map Azure concepts to their AWS equivalents
- Understand the Azure hierarchy
- Install and log in with the Azure CLI
Azure vs AWS β Same Ideas, Different Names
The cloud concepts you learned for AWS transfer directly. Only the names change:
| Concept | AWS | Azure |
|---|---|---|
| Virtual server | EC2 | Virtual Machine (VM) |
| Object storage | S3 | Blob Storage |
| Identity & access | IAM | Microsoft Entra ID + RBAC |
| Networking | VPC | Virtual Network (VNet) |
| Managed database | RDS | Azure SQL Database |
| Serverless functions | Lambda | Azure Functions |
π‘ You already know the concepts
If you understood the AWS section, you already understand 80% of Azure. Focus on learning the naming and the console β the underlying ideas (compute, storage, identity, networking) are the same.
The Azure Hierarchy
Azure organises everything in a clear hierarchy:
Management Group (optional, groups subscriptions)
βββ Subscription (billing + access boundary)
βββ Resource Group (a folder for related resources)
βββ Virtual Machine
βββ Storage Account
βββ Virtual NetworkThis structure β especially the Resource Group β is one of Azureβs nicest features, and itβs the focus of the next lesson.
Install & Log In with the Azure CLI
# Install on Ubuntu / WSL:
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
az login # opens a browser to authenticate
az account show # confirm the active subscriptionπ§ͺ Hands-on
Get Started with Azure
- Create a free Azure account (it includes free credits and always-free services).
- Explore the Azure Portal β find Virtual Machines, Storage accounts, and Resource groups.
- Install the Azure CLI and run
az login. - Run
az account showto confirm your subscription.
π§ Knowledge Check
What is the Azure equivalent of an AWS EC2 instance?
Which Azure concept is a billing and access boundary that contains resource groups?
πΌ Interview Preparation
Why might a company choose Azure over AWS?
Summary
You now understand what Azure is, how its concepts map to AWS, the subscription β resource group β resource hierarchy, and how to log in with the CLI. Next, we organise resources with Resource Groups.
