How to Reduce Bandwidth Usage and Optimize Website Performance with W3 Total Cache and Amazon CloudFront

My website is hosted by Rochen, a company whose services I am very happy with. For reasons I understand they do not offer unlimited data transfer. My account, for example, comes with 50 GB per month. That is a lot and enough for most sites, including mine at this point in time. But I am selling software, and if a big news site writes about SetACL Studio the least of all things I want to happen is that Rochen suspends my account because the transfer limit has been reached.
