You can read about it here, here, and here. A CDN-as-a-Service (CaaS?). Does this put the nail in the coffin and make the CDN business a commodity? Probably.
What impresses me most is not the technology or the pricing or the ease of use of the new service (called CloudFront btw). What really gets me hot is the fact that the AWS Service Health Dashboard already has the performance and uptime of CloudFront up and live! That my friends is sign of true commitment to transparency, and more importantly a well functioning process.
