This is what Microsoft can do for you. ( https://learn.microsoft.com/en-us/azure/azure-sql/database/automatic-tuning-overview?view=azuresql )
Well how can a DBA do this in a simple way?
You analyze it with Claude code using Brent Ozar’s sp_BlitzIndex @AI = 2.
You want the query and test is before and after the index was added, to see the impact.
And see the difference, also keep an administration about the usage, if it has impact on others loads, drop it.
Did I mention ‘simple’ somewehere?!
