App Service Environment version 1 and version 2 will be retired on 31 August 2024

Published date: March 28, 2022

In August 2021, we announced Azure Cloud Services (classic) will be retiring on 31 August 2024. As App Service Environment version 1 and version 2 run on Azure Cloud Services (classic), we will retire App Service Environment version 1 and version 2 on the same date. Before that date, please migrate to App Service Environment version 3.

App Service Environment is an App Service feature that provides a fully isolated and dedicated environment for securely running App Service apps at high scale. App Service Environment version 3 is easier to use, runs on more powerful infrastructure that can go up to 8 cores and 32 GB RAM with faster scaling speeds for both Windows and Linux, and has much simpler network topology. Here’s a quick comparison between App Service Environment version 1/version 2 to version 3.

App Service Environment version 1 and version 2

App Service Environment version 3  

  • Management of front-end scaling required 

  • App Service Environment version 3 runs on newer and more performant Virtual Machine Scale Sets infrastructure 

  • No access across global peering  

  • Apps in internal VIP App Service Environment version 3 can be reached across global peering  

  • Flat Stamp Fee for each App Service Environment  

  • Price savings due to elimination of Stamp Fee and access to use reserved instance pricing  

After 31 August 2024, App Service Environment version 1 and version 2 will no longer be supported and these App Service Environments and the applications running on them will be no longer available. 

Required action
