Deploy and Manage Azure Compute

☁️ Deploy and Manage Azure Compute

Azure Compute provides on-demand resources to run applications and workloads in the cloud.

The most common compute services are:

• Azure Virtual Machines (VMs)
• Azure Virtual Machine Scale Sets (VMSS)
• Azure App Service
• Azure Containers (ACI, AKS)
• Azure Functions

🖥️ Azure Virtual Machines (VMs)

🔹 Deploying a VM

You can create a VM using:

• Azure Portal
• Azure CLI
• ARM / Bicep templates

Key steps:

1. Choose VM size (CPU, RAM)
2. Select OS image (Windows/Linux)
3. Configure authentication (SSH key / password)
4. Select virtual network & subnet
5. Attach disk (OS + data disks)
6. Configure network security group (NSG)

🔹 Managing Azure VMs

• Start / Stop / Restart
• Resize VM
• Attach or detach disks
• Monitor performance (CPU, memory, disk)
• Apply updates and patches
• Backup and restore

⚖️ Virtual Machine Scale Sets (VMSS)

VMSS allows you to deploy and manage multiple identical VMs.

🔹 Key Features

• Auto-scaling based on demand
• High availability
• Load balancer integration
• Cost-effective for web apps

Use case:

Web applications with variable traffic.

🌐 Azure App Service (PaaS Compute)

A fully managed platform to host web apps and APIs.

🔹 Features

• No server management
• Built-in scaling
• Supports .NET, Java, Node.js, Python
• Easy CI/CD integration

Best for:

Developers who don’t want to manage OS or infrastructure.

📦 Azure Containers

🔹 Azure Container Instances (ACI)

• Run containers without managing servers
• Fast startup
• Best for short-lived workloads

🔹 Azure Kubernetes Service (AKS)

• Managed Kubernetes
• Automatic upgrades
• High scalability

⚡ Azure Functions (Serverless Compute)

• Event-driven compute
• Pay only for execution time
• Used for automation and microservices

🔐 Security & Governance

• Network Security Groups (NSG)
• Azure Defender for Cloud
• Role-Based Access Control (RBAC)
• Managed identities
• Disk encryption

📊 Monitoring & Management Tools

• Azure Monitor
• Log Analytics
• Application Insights
• Azure Backup
• Azure Update Manager
•
