1 By default, the timeout for the Functions 1.x runtime in an App Service plan is unbounded.
2 Requires the App Service plan be set to Always On. Pay at standard rates.
3 These limits are set in the host.
4 The actual number of function apps that you can host depends on the activity of the apps, the size of the machine instances, and the corresponding resource utilization.
5 The storage limit is the total content size in temporary storage across all apps in the same App Service plan. Consumption plan uses Azure Files for temporary storage.
6 When your function app is hosted in a Consumption plan, only the CNAME option is supported. For function apps in a Premium plan or an App Service plan, you can map a custom domain using either a CNAME or an A record.
7 Guaranteed for up to 60 minutes.
8 Workers are roles that host customer apps. Workers are available in three fixed sizes: One vCPU/3.5 GB RAM; Two vCPU/7 GB RAM; Four vCPU/14 GB RAM.
9 See App Service limits for details.
10 Including the production slot.
11 There's currently a limit of 5000 function apps in a given subscription.
