Keep Azure SQL Premium RS
Microsoft should reconsider retiring the Premium RS tier of Azure SQL. It provides a service for companies like ours that want to host their QA/Staging environments in Azure but don't need the full reliability of the Premium tier. None of your other offerings will work for us. We make use of In-Memory tables (OLTP). This option is only available in the Premium/Business Critical tiers. Both of which are too expensive for QA/Staging environments. To retire this option without providing anything of comparable value is a mistake. How can customers feel confident in moving their applications to the cloud if Microsoft is going to pull the features that make it possible without providing a suitable replacement?

We use Premium RS for the high IOPS and to change to vCore Business Critical or Premium (the only alternatives which high IOPS) will see a 4x cost which is an additional £130k per year. A cost increase of this magnitude means the cost to run the service outweighs the value.
