Suggestion for any Backend Solution?

Hi,

I'm currently planning to develop a game with saving data quite similar to Clash of Clans. I need a data storage and a chatroom functions for guilds, meanwhile the game will provide login on different social media platform, anonymous login and email login. The game will get some setting files from a CDN functions too. I'm doing research on any MBASS that does provide all the functions? Thanks for anyone who are willing to share the knowledge with me
