Azure Classroom Series – 25/Feb/2021

Azure App Service

• This is HTTP(s) based service hosting for web applications, REST APIs and mobile backends
• App Engine Supports applications written in
  • .NET
  • .NET CORE
  • Java
  • Python
  • Node Js
  • Ruby
  • Docker Containers
• App Service run and scales with ease on Linux and Windows Environments
• App Service Plans:
  • App Service plan defines a set of compute resources for web app to run
  • Each App Service plan defines
    • Region
    • Number of VM instances
    • Size of VM Instances (Small, Medium, Large )
    • Pricing Tier (Free, Shared, Basic, Standard, Premium, Premium V2, Premium V3, Isolated )
• Pricing Tier determines App Service Features and how much we pay for the plan. There are the following categories on app service pricing tier
  • Shared Compute:
    • Free and Shared are the two base tiers are part of this category
    • This tiers allocate CPU quotas to each app that runs on shared resources.
    • Shared resources cannot be scaled out
  • Dedicated Compute:
    • Basic, Standard, Premium, Premium V2, Premium V3 tiers run apps on dedicated Azure Vms
    • Only Apps in same App service plan share the same compute resources.
    • Scale out is possible
  • Isolated:
    • Isolated tier runs on Azure Vms on dedicated networks
    • This offers network isolatation on top of compute isolation
• Lets Explore Features for Windows App Service Plans
• Exercise: Explore features for Linux App Service Plans as well

Lets Explore App Service using various Technologies
