These tiers allocate CPU quotas to each app that runs on the shared resources. The resources can't scale out. These tiers are intended for only development and testing purposes. |

These features include custom domains and TLS/SSL certificates, autoscaling, deployment slots, backups, Azure Traffic Manager integration, and more.

 Except for the Free tier, an App Service plan carries a charge on the compute resources that it uses:
 
 - **Shared tier**: Each app receives a quota of CPU minutes, so *each app* is charged for the CPU quota.
-- **Dedicated compute tiers (Basic, Standard, Premium, PremiumV2, PremiumV3)**: The App Service plan defines the number of VM instances that the apps are scaled to, so *each VM instance* in the App Service plan is charged. These VM instances are charged the same, regardless of how many apps are running on them.

 - The app needs resources in a different geographical region. This way, you can allocate a new set of resources for your app and gain greater control of your apps.
