Before dropping a cloud server, ensure that it is stopped. If necessary, extract any databases running on the cloud server
or move the databases to another cloud server.
The cloud server is dropped and any data files associated with it are deleted.
You cannot drop the cloud server running the primary database in a tenant mirroring system. You must first initiate failover
so that the primary database becomes the mirror, at which point the cloud server can be dropped.
You cannot drop a cloud partner or a cloud arbiter.
