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

Published date: April 21, 2023

In August 2021, we announced Azure Cloud Services (classic) will be retiring on 31 August 2024. As App Service Environment v1 and v2 run on Azure Cloud Services (classic), we will retire App Service Environment v1 and v2 on the same date. Before that date, you must migrate to App Service Environment v3.

After 31 August 2024, App Service Environment v1 and v2 will no longer be supported and these App Service Environments and the applications running on them will be deleted and any application data associated with them will be lost.

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 v3 is easier to use, runs on more powerful infrastructure that can go up to 64 cores and 256 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 v1/v2 to v3.

App Service Environment v1 and v2

App Service Environment v3  

  • Management of front-end scaling required 

  • App Service Environment v3 runs on newer and more performant Virtual Machine Scale Sets infrastructure 

  • No access across global peering  

  • Apps in internal VIP App Service Environment v3 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  

Required action 

To avoid service disruption, please follow the steps to migrate to App Service Environment v3 by 31 August 2024.
