In my search for the hosting of my website. I came across the Cloudways which are the managed cloud hosting service provider. They are offering managed elasticsearch hosting enabled just on one click. So is it possible elasticsearch can be enabled on just one click or we have to do it through conventional method and that is installing it manually.
Managed Elasticsearch is certainly a real thing some folks provide. Elastic has one for sites, one for apps, and a general purpose one. I've worked with some of the folks that work on those products and I trust them. I can't speak to cloudways but I expect that they are good people and would probably do just fine. I'd experiment with a few of them and see which one you like.
