Amazon's S3 cloud storage is usually used by developers, but it can also be used to host static web pages cheaply. The feature, which was first introduced around a year ago, has been updated today to make it easier. Previously, hosts would either have to use a proxy server or force users to enter "www."
The new update utilizes Amazon's Route 53 DNS service and users can now configure it so that it doesn't require visitors to enter "www" when visiting the website. It also removes the need for proxy servers, which reduces the number of points for failure. Amazon offers up this walkthrough to explain the process.
It's a cheap way to host a website as you only pay for the data used. For a small site, it's perfect.
