Has anyone here done this for their web app? I am considering some grid-server space from MT, but if EC2 is good, it seems like it's cheap; is this a viable option?
I recently signed up w/Joyent and am happy with it so far, have also heard good things about SoftLayer, ServerBeach, RackSpace, Layered Tech...some of the other names you hear thrown around on here.
EC2 is probably a better option once you've been around for awhile and that economy of scale starts working in your favor.
