Enable Locks at Database and Collection Level as well to avoid deletion.
We can enable locks at Resource level to make sure Cosmos DB is not deleted. Currently it will still allow the admin to delete the Database and delete the collection under the db. It will be nice to lock the DB and Collection as well. So in Production Environment we can enable these locks to make sure they are not deleted by anyone.
Putting a lock on a resource is possible today in ARM. https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-lock-resources
We partially support this today and plan on fully supporting by end of Summer. Will update here when complete.
