Where Amazon's Data Centers Are Located

Amazon (AMZN) has announced the launch of its content delivery network, which it has dubbed CloudFront. The new offering, part of Amazon's utility computing operation, offers content delivery with "low latency, high data transfer speeds, and no commitments."

As part of the rollout, Amazon has also disclosed the locations where it will cache web content, offering the first public details about where its data centers are located. Here's the list:

UPDATE: In April 2010 Amazon began offering AWS services from an Asia Pacific Zone based in a Singapore data center, which we've added to the list.

The locations of Amazon's data centers has been a topic of interest since the company first offered geographic diversity for its AWS services last year. At the time, Amazon sad it could spread user content across "zones" in the US and Europe to improve redundancy, but didn't address the locations of the content.

Amazon is known to operate a large data center in Ashburn, Virginia in a building now owned by Digital Realty Trust.

Developers serving content from Hong Kong and Tokyo nodes will pay a premium, reflecting the higher cost of data center services and connectivity in those markets.

"Because our costs vary by location, pricing for data served from edge locations outside of the US varies, and is currently slightly higher," Amazon's Jeff Barr writes on the AWS blog. "You will also pay the usual S3 price for the 'origin fetch' which take place when a requested object is transferred from S3 to an edge location, and for storage of the object in S3."

"Amazon CloudFront has been designed to be fast; the service will cache copies of the content in edge locations close to the end-user's location, significantly lowering the access latency to the content," Amazon CTO Werner Vogels writes on his All Things Distributed blog. "High sustainable data transfer rates can be achieved with the service especially when distributing larger objects. "
