Have you ever managed your own non-trivial Elasticsearch cluster personally? Elasticsearch is filled with so many subtle gotchas that aren't present in other non-distributed databases. I personally feel once you've managed your own ES cluster for awhile, you tell yourself there's no freaking way any cloud system can abstract all these ugly (but important) configuration settings and corner cases into a neat, nice cloud product. No freaking way. I'm gonna manage this myself.
