Customers in Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD, can now hibernate Amazon EC2 instances running the Microsoft Windows Server 2022, Red Hat Enterprise Linux 9, and Amazon Linux 2023 operating systems. 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, and your 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.

Hibernate is available through Amazon CloudFormation, Amazon Web Services Management Console, or through the Amazon SDKs, Amazon Tools for Powershell, or the Amazon Command Line Interface.
