Funny considering the main issue we had with EC2 was amazons horrible support. Even spending a lot (lot) per month our only option was to post on the forums and wait. We ended up at Rackspace after a few years of frustrating issues.
Well, support is relative. If you found Amazon's "horrible", you would find Google's utterly horrible and scary beyond any description.
Free tier - occasionally get answers. answers are generally vague. questions to forums. Paid tier - always get answers. answers are generally vague. you get a support portal. Top tier paid - always get answers. answers are generally vague. amazon employees will fly out to your site to give vague answers.
(I mean, beside the 'default' ones)
