As far as I can tell, cloud computing is a cheaper more efficient way of serving web pages.
Today, hosting provider Rackspace is offering a new cloud computing service through its subsidiary Mosso. (Disclosure: Rackspace is a TechCrunch advertiser). The service competes with Amazon’s Elastic Compute Cloud (EC2), although it doesn’t require any load balancing or other administration. It also competes with Joyent and Media Temple’s Grid Service. Pricing starts at $100 a month for:
—50 GB of storage
—500 GB of bandwidth for transferring data
—3 million HTTP requests.
From there additional capacity per month costs:
—$0.50/GB of storage
—$0.25/GB of bandwidth
—$0.03/1,000 HTTP requests
This is a bit more expensive than Amazon (which charges in a different way) but a lot cheaper than the $350 to $400 a month Rackspace charges to host a dedicated server for a Website.
