Running XMPP on Amazon for a chat app
As an employee of ProcessOne, the makers of ejabberd, I can tell you we run a lot of services over AWS, including mobile chat apps. We have industrialized our procedures.
I'm building an Android IM chat app for fun. I can develop the Android stuff well but i'm not so good with the networking side so I am looking at using XMPP on AWS servers to run the actual IM side. I've looked at OpenFire and ejabberd which i could use. Does anyone have any experience with them or know a better one? I'm mostly looking for sending direct IM between friends and group IM with friends.
