Just a really quick FYI for the readers. If you are using Managed Instances in Azure (If not, why not?) and you connect vis SSMS (SQL Server Management Studio) and run the classic commands SELECT @@VERSION, what will you see?
On the theme of failover groups let’s do a quick recap on my environment. As shown below you can see the secondary database server called spacesql in West Europe.
You have an Azure SQL Database, it could be a single database, it could be a primary database within a failover group. Regardless of the context, what would you do if you need to upgrade the compute tier for the database but then you decide you no longer want to do this and want to immediately cancel it? In the past people just let the system carry out the task then once complete, rollback.
It is quite a common requirement to restore a copy of a database to the same Azure SQL server, you just issue a COPY OF command. What if you need to restore a copy to a different target Azure SQL server? Well its similar, just with a slight difference in that you need to refer back to the source server within your code.
Being aligned to a global cloud like Microsoft Azure you have choices. Whether that is Azure SQL Database or Azure Database for MySQL for your relational database, it does not matter that is down to you are your design choices. The point here is that Azure has variations and flexibility with so many choices and this is no different within the “Big Data” analytics space.
