Manage an App Service plan in Azure
An App Service plan provides the resources an App Service app needs to run. This how-to guide shows how to manage an App Service plan.
Create an App Service plan
If you have an App Service Environment, see Create an App Service plan in an App Service Environment.
You can create an empty App Service plan or as part of app creation.
In the Azure portal, click New > Web + mobile, and then select Web App or other App Service app kind.
You can then select an existing App Service plan or create a plan for the new app.
To create an App Service plan, click [+] Create New, type the App Service plan name, and then select an appropriate Location. Click Pricing tier, and then select an appropriate pricing tier for the service. Select View all to view more pricing options, such as Free and Shared.
After you have selected the pricing tier, click the Select button.
Move an app to another App Service plan
You can move an app to another App Service plan as long as the source plan and the target plan are in the same resource group and geographical region.
To move an app to another plan, navigate to the app that you want to move in the Azure portal.
In the Menu, look for the App Service Plan section.
Select Change App Service plan to start the process.
Change App Service plan opens the App Service plan selector. Select an existing plan to move this app into.
The Select App Service plan page is filtered by the following criteria:
- Exists in the same resource group
- Exists in the same geographical region
- Exists in the same webspace
A webspace is a logical construct in App Service that defines a grouping of server resources. A geographical region (such as West US) contains many webspaces in order to allocate customers using App Service. Currently, App Service resources aren’t able to be moved between webspaces.
Each plan has its own pricing tier. For example, moving a site from a Free tier to a Standard tier, enables all apps assigned to it to use the features and resources of the Standard tier. However, moving an app from a higher tiered plan to a lower tiered plan means that you no longer have access to certain features. If your app uses a feature that is not available in the target plan, you get an error that shows which feature is in use that is not available. For example, if one of your apps uses SSL certificates, you might see the error message:
Cannot update the site with hostname '<app_name>' because its current SSL configuration 'SNI based SSL enabled' is not allowed in the target compute mode. Allowed SSL configuration is 'Disabled'.In this case, you need to scale up the pricing tier of the target plan to Basic or higher, or you need to remove all SSL connections to your app, before you can move the app to the target plan.
Move an app to a different region
The region in which your app runs is the region of the App Service plan it's in. However, you cannot change an App Service plan's region. If you want to run your app in a different region, one alternative is app cloning. Cloning makes a copy of your app in a new or existing App Service plan in any region.
You can find Clone App in the Development Tools section of the menu.
Cloning has some limitations that you can read about at Azure App Service App cloning.
Scale an App Service plan
To scale up an App Service plan's pricing tier, see Scale up an app in Azure.
To scale out an app's instance count, see Scale instance count manually or automatically.
Delete an App Service plan
To avoid unexpected charges, when you delete the last app in an App Service plan, App Service also deletes the plan by default. If choose to keep the plan instead, you should change the plan to Free tier so that you don't get charged.
App Service plans that have no apps associated to them still incur charges since they continue to reserve the configured VM instances.
