LeaderBoard

Hi All,

I am developing my first game and I would like to include a leader board. The leader board will be in place for one time tournament: the users will send their score only once and the tournament will last for 2 weeks. I had a look at different platform (unisave, Pubnub) but I would need an advice from someone that has more experience than me. How can I choose which platform to implement ? Let's say that I will have 3 possible cases with users a)100 and b)10000 and c)100000. How can be sure that the platform is not undersized (too many users) or oversized (I pay too much for my needs) ?

Thank you in advance to who can advice me.

Regards,
Stefano
