We've found the cloud structure and pay-by-the-hour billing to be ideal with larger customers. If they're not already spending $200/month on hosting fees, the cloud is likely not for them. Once they're into the $200/month range and advertising with traffic and load spikes on their websites, the cloud is a great solution. It's not geared for small mom and pop sites, but if you have a site with a lot of traffic or CPU processing needed, the cloud options are a wonderful solution. Much easier (and less expensive) than setting up clustered machines which was the old way.
