Amazon continues to widen its gap in the SOA CloudScape with its launch of CloudFront. CloudFront essentially delivers content via a network of edge locations, promising low latency and high data transfer speeds. CloudFront is pay as you go (ie no sales negotiations or commitments). Woot uses CloudFront for image hosting. PlayFish also uses CloudFront to deliver games. This is one service which will tip the scales for many enterprises thinking about using the cloud. One thing to note, however: if you are transferring huge amounts of data, it will likely be more cost effective to use Akamai (which is essentially cloud computing if you think about it).
