With the confidential VM option for SQL Server on Azure Virtual Machines, you can now run your SQL Server workloads on the latest AMD-backed confidential virtual machines. This ensures that both the data in use (the data processed inside the memory of the SQL Server) as well as the data at rest stored on your VM’s drives, are inaccessible to unauthorized users from the outside of the VM. This can be done without the need to change the code of your SQL Server applications or your database schemas, including stored procedures.
