Today, we are pleased to announce that Amazon CloudFront has added a new type of edge location called Regional Edge Cache that further improves performance for your viewers. Regional Edge Caches, in addition to improving performance, also help reduce the load on your origin resources, minimizing operational burden associated with scaling your origin and reducing your origin costs.  Regional Edge Caches are turned on by default for your CloudFront distributions; you do not need to make any changes to your distributions to take advantage of this feature. There are also no additional charges to use this feature.
