What cloud storage are people using with Sencha?

When designing a mobile app, it's common to need to line up a cloud storage service for account management, data storage, real-time updates, etc. What are other people using with Sencha?

There are lots of options for hosted services, including running my own db server. But what about other features like iOS notifications, etc? Sencha Space seems a bit much for someone developing a smaller stand-alone app for the app store, and it's hard to tell if it does everything sencha.io was meant to do before they canned it.

Thanks!
