For the last 2years I've been developing and deploying professionally, tens of Ruby on Rails application using Hatchbox.io .
Hatchbox has great support for cloud providers such as AWS, Digital Ocean and custom VPS.
Before using Hatchbox, I used Heroku and the features are similiar at one fraction of a cost.
You can also choose which database you want to use, such as Postgresql, Mysql, Mongodb. There is also support for Redis, Memcache.
Background jobs are executed via Sidekiq.
