What is the best choice for me?

Hello everyone :smiley:
We are making a videogame, its already up in the iOS store, we want to make this game more viral and more social, and we desing a structure of strings so we can save the data of every user that login into the game, i want to know what kind of server its the best for this. We are going only to read and write data in SQL database, no image only strings, bools, ints, very simple data we have already 5,000 active users per day, and we are think that can grow really fast but there are going to be mostly 5,000 users reading and update the data of the database.

Thank you for reading :smiley:
