If you're looking to deliver your website via a content delivery network or content distribution network like Akamai, Limelight, or CDNetworks, you've got a few alternatives to consider (especially on the cost point).
- Amazon is set to release a new pay-as-you-go content delivery service before the end of the year. It's also built to integrate with Amazone S3 for storage.
- Coral is a free CDN built on peer-to-peer technologies. Seems like it's being run as some sort of test project but it's free.
In case you're interested, www.westernaustralia.com has been delivered through Akamai since early August. We reduced international load times from an average of 43.5 seconds to 5.5 seconds on go-live but pay a hefty annual fee for the privilege. We're using their standard geographic caching service and their Dynamic Site Accellerator product to speed up requests that do have to hit our Perth-based servers.
