We use AWS, but it's expensive and have a lot of tricks and hidden issues. I'd like to move towards a PaaS provider, but don't know which one.
Applications are written in php and rails.
I know/have tried Google App Engine and Heroku. Would you advocate for one of these? Would you suggest anything else? Why?
I think it's cheaper than IaaS on Azure, but I'm not sure. I never compared them that well. Fortunately there's a pricing calculator on azure.com.
