Determining an Appropriate Service Tier
As a SQL Server DBA, when migrating to an Azure SQL Database, you will need to have an initial estimate of DTUs so as to assign an appropriate Service tier to an Azure SQL Database. An appropriate Service Tier will ensure that you met most of your application performance goals. Estimating a lower or a higher Service tier will result in decreased performance or increased cost, respectively.
This chapter teaches you how to use the DTU calculator to make an appropriate initial estimate of the Service tier. You can, at any time, change your service tier by monitoring the Azure SQL Database performance once it's up and running.
