I have an app service (Azure Mobile App) that I just noticed seems to get unloaded when there are no active clients for a while--typically 5PM to 6AM.
It sometimes takes a few minutes for the service to "come alive" again when the first client of the day requests data, and that's not a good experience for that client.
How do I make sure it remains loaded/kept alive?
This is the Memory working set, Avg graph which is what clued me into thinking it's getting unloaded.
I just found out from the Azure Portal to allow "Always On," I need at least Basic
If you don't want to upgrade the tier, you can simply run a schedule tasks somewhere (Azure Function for example) to periodically ping the service.
This is known as cold start. Have you tried to set Always On on App Settings?
