I have been fooling around with the hub demo and I am wondering a few things before I feel good about pulling the trigger.

How do you shutdown a server and start it back up? It seems that you can only shutdown. Does this mean I have to launch a new sever everytime I want to bring my instance back online and then restore? I don't want to leave my VM on all the time, I just want it on when I need it.

Do elastic IP cost extra? I assume I can have an elastic IP and then point my domain to it and I can then assign that to any VM I want and I always "own" that IP?

I also don't see how creating an EBS volume works very well, maybe this is because there is no console in the demo? When you attach an EBS volume, does it auto mount in the VM? When I make modifications to my VM are those changes saved to the EBS volume?

Anyway, thanks very much for helping me understand this all better. I searched for answers on forums and in documentation and didn't turn anything up, so I decided to post.

Thanks again.
