Microsoft Azure is the second-largest global public cloud by customer revenues, according to independent analyst estimates, and Microsoft now claims an Azure presence in twice as many regions as the public cloud market-leading Amazon Web Services (AWS). “Over the last several years we’ve been hard at work expanding it to run literally all over the world,” said Scott Guthrie, executive vice president for the Microsoft Cloud and Enterprise Group, in an Ignite keynote Monday. “We now have 34 unique Azure regions around the world.”

Guthrie described Azure regions as clusters of multiple datacenters that are geographically close to customers to allow them to access data and computing power faster.  The list includes 30 generally available regions, including a pair that just opened in Germany, where Microsoft previously didn’t have a presence. “The Microsoft Cloud is also the only global cloud vendor licensed to operate legally in China, and the only to offer full data sovereignty in Germany, using our data trustee model,” Guthrie said.

Azure is generally available in 30 regions around the world, and has announced plans for 4 additional regions. Geographic expansion is a priority for Azure because it enables our customers to achieve higher performance and it support their requirements and preferences regarding data location.
