Microsoft Azure Virtual Machines Cheatsheet: Cloud Computing Platform

Overview

Microsoft Azure Virtual Machines provide scalable, on-demand computing resources in the cloud, offering flexible infrastructure deployment and management.

Core Concepts

• Infrastructure as a Service (IaaS)
• Scalable Compute Resources
• Hybrid Cloud Integration
• Pay-as-you-go Pricing Model

Key Components

1. Virtual Machines

   • Compute resources with customizable configurations
   • Multiple VM series and sizes

2. Azure Resource Manager

   • Deployment and management framework
   • Infrastructure as Code (IaC) support

3. Virtual Networks

   • Network isolation
   • Subnet configuration
   • Network security groups

VM Series and Types

1. General Purpose

   • Balanced CPU-to-memory ratio
   • Web servers, small-to-medium databases

2. Compute Optimized

   • High CPU performance
   • Batch processing, web servers

3. Memory Optimized

   • Large memory capacity
   • Relational database servers

4. Storage Optimized

   • High disk I/O performance
   • Big data, data warehousing

5. GPU

   • Graphics rendering
   • Machine learning
   • High-performance computing
