How Do I Prevent An Azure Cloud Service (Classic) From Going To Sleep (In 2018)?
We have a site that keeps falling to sleep, which causes an error due to the time-sensitivity of our sporadic requests.
I've seen how there is an "Always On" setting in the old Azure console, but it doesn't appear to apply to the new interface:
How to prevent an Azure website from going to sleep?
Where is this setting now, or how do I do the equivalent?
Here's what I see:
There's a couple of options. One of those is to use Traffic Manager Endpoint Monitoring which keeps calling your app so it doesn't recycle. Or is automatically started again when it does.
According to the blog post Windows Azure WebSites and Cloud Services Slow on First Request you can "include a script with your package, which is configured to run as a startup script, every time the role is restarted."
REM *** Prevent the IIS app pools from shutting down due to being idle.
%windir%\system32\inetsrv\appcmd set config -section:applicationPools -applicationPoolDefaults.processModel.idleTimeout:00:00:00
REM *** Prevent IIS app pool recycles from recycling on the default schedule of 1740 minutes (29 hours).
%windir%\system32\inetsrv\appcmd set config -section:applicationPools -applicationPoolDefaults.recycling.periodicRestart.time:00:00:00
How to proceed with the configuration can be found under "Avoid automatic recycle of Azure Cloud Services Web Role" of that post.
