Backend for Mobile app configuration
I need a backend for a mobile app. PHP+MySql. The tasks are quite simple, I don't expect more than around 10 queries per user session.
My idea is Ubuntu but I have no much experience with it and I will be using it sporadically, probably I will need the expertise when there's something urgent to fix. To leverage this I am thinking on some Control Panel, so far I am seeing VestaCP, Ajenti and Server Pilot (or at least they look like CPs to me at first glance :-) I don't need the web server that seems to be the core of most of the CPs.
Do you have any suggestion about this (even the OS, it may be any the simpler as far as it supports PHP+mySql). Oh, and secure!
