Scaling Azure SQL

The required performance of your database may differ depending on the time and current state of your application. This is when scaling is all-important—you can adjust cost and available resources depending on the needs of your service. In Azure SQL, there are multiple different scenarios that you will need to consider: whether you wish to use a single database or an elastic pool, whether you need to scale out reads, or whether you need all features available everywhere. In this short section, I will show you how to quickly proceed with your decision and where you can find scaling tools.

Single database

As we mentioned previously, with a single database, scaling is simple—you just need to go to the Compute + storage blade and select the new tier you are interested in. You can easily decide whether you need to scale a database up by watching its performance, as demonstrated in the following screenshot:
