- You can move an app to another App Service plan, as long as the source plan and the target plan are in the same resource group and geographical region.
The region in which your app runs are the region of the App Service plan it’s in. However, you cannot change an App Service plan’s region.
- Availability Set Fault domain and Update domain >> Use two fault domains.
2 or 3 is max value, depending on which region you are in.
Use 20 for platformUpdateDomainCount
Increasing the update domain (platformUpdateDomainCount) helps with capacity and availability planning when the platform reboots nodes. A higher number for the pool (20 is max) means that fewer of their nodes in any given availability set would be rebooted at once.
