I was curious, given the amazing rate Amazon has been improving Cloudfront, if they had decided to eat their own dog food yet and use it as the primary CDN on their crown jewel – the main Amazon.com site. They had previously entrusted Akamai for the majority of their CDN needs.
Long story short – absolutely. Of the 163 external resources on the main page, 74 of them are hosted on Cloudfront – compared to 46 on Akamai (the rest are a mixture of doubleclick, etc.). That’s pretty impressive.
Below is a dump of all of the URL’s, sorted by count with their hosting CDN.
g-ecx.images-amazon.com, for example, is hosted on Cloudfront:
;; ANSWER SECTION:
g-ecx.images-amazon.com. 49 IN CNAME d1ge0kk1l5kms0.cloudfront.net.
d1ge0kk1l5kms0.cloudfront.net. 14 IN CNAME d1ge0kk1l5kms0.iad12.cloudfront.net.
while z-ecx.images-amazon.com is hosted on Akamai:
;; ANSWER SECTION:
z-ecx.images-amazon.com. 60 IN CNAME z-ecx.images-amazon.com.edgesuite.net.
z-ecx.images-amazon.com.edgesuite.net. 8725 IN CNAME a1248.g.akamai.net.
g-ecx.images-amazon.com => 56 (cloudfront)
z-ecx.images-amazon.com => 27 (akamai)
images-na.ssl-images-amazon.com => 15 (akamai)
www.amazon.com => 10 (Other)

Kudos to Amazon for making the move.
