title: Store application data on a server
body: <p>I'm developing an android app. And now I have a problem. I need to store app data somewhere on server side.
  For example I want to store user rating by other users and some other data.
  I don't want to develop my own server and API.
  I mean I want any cloud-base platform for it.
  What can I use for server-side data storage?</p>
