Azure Complete Guide: Master Microsoft Cloud Platform in 2026

What is Microsoft Azure?

Microsoft Azure is the second-largest cloud computing platform globally, offering 200+ services spanning compute, storage, networking, databases, AI, analytics, and more. Azure integrates deeply with the Microsoft enterprise ecosystem — Active Directory, Windows Server, SQL Server, Microsoft 365, and the Power Platform — making it the natural choice for organizations already using Microsoft technologies.

With 60+ data center regions worldwide (more than any other cloud provider), $85+ billion in annual cloud revenue, and industry-leading hybrid cloud capabilities through Azure Arc, Azure powers everything from small startups to the world's largest enterprises, governments, and healthcare organizations.

Why Learn Azure in 2026?

Who Is This For?

• System Administrators — Managing enterprise infrastructure on Azure
• DevOps Engineers — Building CI/CD pipelines with Azure DevOps
• Cloud Architects — Designing scalable Azure solutions
• Developers — Building and deploying applications on Azure App Service, Functions
• IT Professionals — Transitioning from on-premise to cloud infrastructure

How Azure Works

Azure organizes resources through a clear hierarchy:

Azure CLI Essentials

# Install Azure CLI
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

# Login to Azure
az login

# Set default subscription
az account set --subscription "My Subscription"

# Create resource group
az group create --name myRG --location westeurope

# List all resources in a group
az resource list --resource-group myRG --output table

Azure Virtual Machines

# Create Ubuntu VM
az vm create \
  --resource-group myRG \
  --name myVM \
  --image Ubuntu2204 \
  --size Standard_B2s \
  --admin-username azureuser \
  --generate-ssh-keys

# Open port 80 for web traffic
az vm open-port --port 80 --resource-group myRG --name myVM

# SSH into VM
ssh azureuser@$(az vm show -g myRG -n myVM -d --query publicIps -o tsv)

# Deallocate VM (stop billing for compute)
az vm deallocate --resource-group myRG --name myVM

Azure Networking

# Create VNet with subnet
az network vnet create \
  --resource-group myRG \
  --name myVNet \
  --address-prefix 10.0.0.0/16 \
  --subnet-name mySubnet \
  --subnet-prefix 10.0.1.0/24

# Create Network Security Group
az network nsg create --resource-group myRG --name myNSG

# Allow SSH traffic
az network nsg rule create \
  --resource-group myRG --nsg-name myNSG \
  --name AllowSSH --priority 100 \
  --destination-port-ranges 22 --access Allow \
  --protocol Tcp --direction Inbound

Azure Storage

# Create storage account
az storage account create \
  --name mystorageacct \
  --resource-group myRG \
  --location westeurope \
  --sku Standard_LRS

# Upload file to blob storage
az storage blob upload \
  --account-name mystorageacct \
  --container-name mycontainer \
  --name myfile.txt --file ./myfile.txt

Azure Kubernetes Service (AKS)

AKS is Azure's managed Kubernetes service, making it easy to deploy and manage containerized applications.

# Create AKS cluster
az aks create \
  --resource-group myRG \
  --name myAKS \
  --node-count 3 \
  --generate-ssh-keys

# Get credentials
az aks get-credentials --resource-group myRG --name myAKS

# Verify
kubectl get nodes

Azure SQL & Databases

# Create Azure SQL server + database
az sql server create --name myserver --resource-group myRG \
  --location westeurope --admin-user sqladmin --admin-password 'P@ss!'

az sql db create --resource-group myRG --server myserver \
  --name mydb --service-objective S0

Azure App Service

# Create App Service (PaaS web hosting)
az appservice plan create --name myPlan --resource-group myRG --sku B1 --is-linux
az webapp create --resource-group myRG --plan myPlan \
  --name mywebapp --runtime 'NODE:18-lts'

Azure Functions (Serverless)

# Create and deploy serverless function
func init MyFunc --worker-runtime node
func new --name HttpTrigger --template 'HTTP trigger'
func start  # Run locally
func azure functionapp publish myFuncApp  # Deploy

Identity & Security

# Create service principal for automation
az ad sp create-for-rbac --name myapp \
  --role contributor \
  --scopes /subscriptions/SUB_ID/resourceGroups/myRG

# Azure Key Vault for secrets
az keyvault create --name myVault --resource-group myRG
az keyvault secret set --vault-name myVault --name dbPassword --value 'secret'

Monitoring & Cost Management

Azure Monitor and Cost Management help you track performance and spending. Use az monitor commands and the Azure Advisor for optimization recommendations.
