Back in October, Amazon’s chief technology officer, Werner Vogels, announced at the AWS re:Invent conference that Amazon’s new t2.nano instances would be available later this year. On Tuesday, the company delivered on that promise.

“Like their larger siblings (t2.micro, t2.small, t2.medium, and t2.large), these instances provide a baseline level of processing power, along with the ability to save up unused cycles and use them when the need arises,” Amazon’s chief evangelist for AWS, Jeff Barr, wrote in a blog posting.

At the time of AWS re:Invent, Vogels also announced new high-performing x1 instances that would arrive in the first half of 2016.

The t2.nano instances are available from today in the U.S. East (Northern Virginia), U.S. West (Oregon), U.S. West (Northern California), Europe (Ireland), Asia Pacific (Singapore), Asia Pacific (Tokyo), South America (Brazil), and AWS GovCloud (U.S.) regions. Beyond those markets, they’ll be “available soon” in Europe (Frankfurt) and Asia Pacific (Sydney).

“I expect to see the t2.nano used to host low-traffic websites, run microservices, support dev / test environments, and to be used as cost-effective monitoring vehicles,” Barr said. “There are also plenty of ways to use these instances in training and educational settings.”
