When you create and deploy an operational database in an Azure environment, by default, COD clusters now use Standard_D8s_v3 instance type instead of Standard_D8_v3. The instance type is upgraded to support encryption at the host level.
If you want to retain the Standard_D8_v3 instance type, you must have the COD_USE_DV3_INSTANCE_TYPE entitlement on your account.
This is available starting in COD v1.41 and you do not need to upgrade to a higher version of COD to benefit from this feature.
