I wouldn't think using "standalone" versus whatever would make much of a difference.
If you're using a hosted DB service, you're (probably) stuck in needing/wanting to rehearse using the hosted service (which is what the blog post describes).
If they were running the DB on 'regular server' cloud instances, it seems just as good to me to rehearse with other cloud server instances versus "standalone" servers.
