Jeffrey Verheul mentions that Azure SQL Database databases need regular maintenance, too:
Before I’m going into detail, I want to give full kudos to Ola Hallengren (Website | @olahallengren). He has spend a lot of his time to build a SQL Server Maintenance Solution that is completely free for everyone to use. And he did such an excellent job a lot companies (also huge companies) use his solution to run maintenance tasks on their databases.
None of the scripts below are written by me, but only small changes are made in order to make things more clear when the solution is deployed to an environment. The original scripts can be downloaded via the download page on Ola’s website.
Most of the to-dos are the same between on-premises and Azure SQL DB, but some of the implementation steps are a bit different. This is worth checking out if you have any Azure SQL Database instances.
