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, and applications will resume from right where they left off.
