I got a wcf service which I'd like to run on azure, but I got several problems:

First: do I choose a web role or a worker role for running the wcf service?

Second: The client uses a call to log into the service, afterwards the service should remember who is logged in (sessions). The problem is, for firewall reasons I probably should use some http-binding. But these seem not to support sessions??
Or do I need AppFabric for sessions (what is AppFabric anyway?)?

Is there a good complete tutorial how to host wcf service?
