What are the alternatives to heroku?

Question

Ruby on Rails

The advantages of using heroku I think are obvious to everyone. But their horse price tag is appalling. On the same Amazon, if you buy nodes + postgres, it will be much cheaper. The main feature that I need in Heroku is automatic scaling (adding servers in 1 team) and managed deployment of the application (when the application is first deployed on new servers, and then the load balancer switches to them from the old ones). What are the alternative options? As far as I know, there are no such features in the Amazon (but there are separate load balancer and postgres).
How difficult is it to set up some kind of ansible and what is its reliability (can it turn out so that it deploys half and switches the balancer to a non-working application).
Or I know that there are companies that provide just the right features on top of Amazon / digital ocean, etc. But they somehow do not inspire confidence, maybe someone has experience.

In short, here it is:

PS From myself I will add: do not spare money on Heroku. Sysadmin to support servers will cost more. Our bill for Heroka is about $900 last month, so I know what I'm talking about. Until thousands rise to 7-10, we are unlikely to think about our own servers - more trouble with the support of this zoo. Here, all problems are solved as quickly as possible. There are special corporate rates (we haven't matured yet) with interesting perks for collaboration. And the creator of Ruby works for them, and he knows better than us how to keep a ruby ​​in production :)
