Azure Compute

Azure compute is an on-demand computing services for running cloud based applications.

• Azure Virtual Machines
• Azure Container Instances
• Azure App Service
• Azure Functions (or serverless computing)

Azure Virtual Machines (VMs)

Virtual Machines are virtual computer systems. They include

• Virtual processor
• Memory
• Storage
• Networking resources VMs host an opertaing system, and we can install and run softwares on the VMs just like a physical computer. VMs provide IaaS (infrastructure as a service).

Storage

• OS Disk
• Data Disk
• Temporary Disk (instance)
• Unmanaged vs managed

Operating System

• Windows
• Linux

Connections to VMs

• RDP
• SSH

Region

OS Type (OS Only) Tier (Standered) Category ( General Purpose | Compute Optimized) Instance Series Instance Number of VM

Virtual machine scale sets

Virtual machine scale sets are like image of an operating system
