Saving of player resource data, tile data on a server?

I’m completely new to Unity. However I’m currently working on a obj-c/iOS game which uses parse.com to save pretty much everything, I save the assets to the server so they can be loaded at runtime I save all the players tile data, I save all the players resource data, everything. This also enables me to do a kind of asynchronous game play as all of the data is external.

So my question what would be the best way to do that in Unity? with the aim being to publish for iOS?

Usage of parse in unity is possible.
either use www and their web api or use the api provided by playtomic.

Parse now have an official SDK for Unity (Parse Platform). Fair warning though - as of right now their documentation and support has a lot to be desired. Have to hope this is improved on because, when it works, it’s pretty impressive.
