Hi all, I'm trying to figure out how to choose hardware and best hosting site for a web game server. The server is for hosting games with a Apache,PHP, and Mysql backend, serving a Flash frontend. The problem is I don't have any experience in the subject. How can i estimate the needed Hardware? How can i estimate the needed bandwitch? How can i choose the best location for the hosting knowing the target audience for the games? Not having experience is it best to have server management (security, updates, backups) by the hosting site? Can someone please give me some pointers? Thank you.
