Best Practices for Cloudways?

I have been frustrated with SiteGround, and after reading several reviews, decided to give Cloudways a try.

Their setup is a little different, and I'm having issues with www and non-www resolving to the same place. They prefer http://www.domain.com, and the WordPress Codex strongly suggests domain.com.

Does anyone have any experience with setting up a (functional) multisite with Cloudways, and can pass along that information?
