PhilG To elaborate this you can scale up an app in Azure App Service by increasing the resources such as CPU, memory, disk space, and extra features.
If your app depends on other services, such as Azure SQL Database or Azure Storage, you can scale up these resources separately.
For detailed information, such as VM sizes for each pricing tier, see App Service Pricing Details. For a table of service limits, quotas, and constraints, and supported features in each tier, see App Service limits.
You can also scale down to a lower tier, which saves you money. If your app is in the same App Service plan with other apps, you may want to improve the app's performance by isolating the compute resources. You can do it by moving the app into a separate App Service plan.
For more information, see Move an app to another App Service plan.
