Overview of Azure Services

The Core Services of Azure:

  • Virtual Machines
  • Virtual Networking

Almost every service in Azure is built on one or more of these.

Azure VM and APP Services

What is a Virtual Machine? (assuming if you are studying this course you already know what a virtual machine is…)

  • Windows or Linux
  • Can be accessed using RDP or SSH
  • Can be placed on a virtual network

You are responsible for managing server

Virtual Machines Abstractions

App Services

These are fully managed servers and you don’t have remote access to them.

  • Web apps or container apps
  • Windows or Linux (you cant pick the version)
  • Lots of benefits in scaling, continuous improvement etc…

  • Various levels of replications
  • Storage tiers (hot, cool, archive)
  • Managed (for VMs)or unmanaged
