Best Cloud Service for saving data

Hello to everyone.

My game reached a point where we need to start saving the users data and then retrieve it from a cloud service. I need to store the info of scores, progress, etc

Which good services do you know that can work correctly for this purpose? The only one I know is Parse, but I would love to hear about other options

My game is for iOS. The only requirement that I have is that it must work with this platform. Someone knows if GameCenter stores this data somehow?

Thanks in advance
