You can run programs or scripts in WebJobs in your App Service web app in three ways: on demand, continuously, or on a schedule. There is no additional cost to use WebJobs.
Basic and Standard modes offer the Always On feature which, when enabled, prevents web apps from becoming idle.
If your web app runs on more than one instance, a continuously running WebJob will run on all of your instances. On-demand and scheduled WebJobs run on a single instance selected for load balancing by Microsoft Azure.
For Continuous WebJobs to run reliably and on all instances, enable the Always On* configuration setting for the web app otherwise they can stop running when the SCM host site has been idle for too long.
