There are simply too many services that offer this functionality. What is your favourite one? What would you use for this. I believe there could be Countly that could be integrated into Gideros like MoaiCloud is with Moai (though both can be used with any other framework).
Countly is basically a detailed analytics platform - it doesn't provide backend-as-a-server. If someone is looking for an open source BaaS solution, then usergrid that's acquired by Apigee some time ago is an option: https://github.com/usergrid/stack . I had a preview on it and it is promising. Definitely worth trying out.
