Amazon has opened a new “U.S. West” data center in Oregon. Derrick Harris notes that the company is delivering this to users 10% cheaper than the existing west-coast facility in California. These prices are the same as the U.S. East facility in Virginia, and significantly below the rates charged to users in Europe and Asia. Rich Miller has more on the modular approach Amazon has used in building this data center. It’s not clear how much the design contributes to the lower cost, and how much this is down to cheaper power/cooling/real estate in Oregon.
