EC2 Hibernation is now available in four new regions

Starting today, the EC2 Hibernation feature is now available in the Asia Pacific (Melbourne), Asia Pacific (Hyderabad), Europe (Zurich), and Europe (Spain) AWS Regions. Hibernation is an Amazon EC2 feature that helps lower costs and achieve faster startup times by enabling customers to pause and resume their running instances at scale. Customers are not billed for compute time while instances are suspended, [only their storage volumes](https://aws.amazon.com/ebs/pricing/), and applications will resume from right where they left off. Upon hibernation, an instance’s EBS root volume and any attached EBS data volumes are saved to disk. The data from memory (RAM) is also preserved. When a hibernated instance is resumed, the EBS root volume is restored from its prior state, along with the RAM state and any previously attached data volumes. Customers can configure Hibernate on a [variety of instance types, with new types supported regularly](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/hibernating-prerequisites.html#hibernation-prereqs-supported-instance-families). The hibernation feature is available in commercial [AWS Regions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/hibernating-prerequisites.html#hibernation-prereqs-regions) and the AWS GovCloud (US) Regions. Instance family availability varies by region. Hibernate is available through AWS CloudFormation, AWS Management Console, or through the AWS SDKs, AWS Tools for Powershell, or the AWS Command Line Interface (CLI).
