The new Premium V3 pricing tier gives you faster processors, SSD storage, memory-optimized options, and quadruple the memory-to-core ratio of the existing pricing tiers (double the Premium V2 tier). With the performance advantage, you could save money by running your apps on fewer instances. In this article, you learn how to create an app in Premium V3 tier or scale up an app to Premium V3 tier.

- Create an app in a new resource group and with a new App Service plan. When creating the App Service plan, select the desired Premium V3 tier. This step ensures that the App Service plan is deployed into a deployment unit that supports Premium V3 as well as the specific SKU within Premium V3. Then, redeploy your application code into the newly created app. Even if you scale the new App Service plan down to a lower tier to save costs, you can always scale back up to Premium V3 and the desired SKU within Premium V3 because the deployment unit supports it.
