Running maintenance on Azure SQL databases

To keep your data healthy and topfit, we all know you need to run something called database maintenance on your databases. This prevents things like performance problems or unrecoverable data from happening, and that is sort of the core business of DBA’s. And when we look at how this can be performed on a regular basis, an on-premise instance is a bit easier to maintain than an Azure SQL database. That’s why I want to share our experience with you on that, hoping that it can save you some time when you start implementing this.

 
Platform setup
In order to get a better understanding of why certain choices were made, I want to share a very basic version of the setup of our environment.

Our platform consists of 2 mayor parts: a private cloud part (that we see as “on-premise”), and an Azure part. Those 2 parts combined make our platform, and this platform hosts all of our services, applications, databases, etc. The development approach we use is everything should be designed with cloud-first in mind, but only if it’s the right tool for the job, and with the exclusion of some data.

The databases we use in Azure are all what Microsoft calls “Azure SQL databases”. This means that there are no virtual machines of any kind are running on our Azure-part of the platform, also known as DBaas (Database as a Service). Continue reading Running maintenance on Azure SQL databases
