Pause and Resume Your Workloads features enabled by Amazon EC2

This feature is accessible for On-Demand and Reserved Instances executing on recently initiated M3, M4, M5, C3, C4, C5, R3, R4, and R5 instances executing Amazon Linux 1. The AMI snapshot used to start the instance should be encrypted. This guarantees security of sensitive contents in memory (RAM) as they get cloned to the root volume. Now, you can pause your Amazon EC2 instances backed by Amazon EBS and restart them at a later time. You can start applications from just where they left off rather than recreating the memory footprint all over again. For example, applications which depends on caches and other memory-centric components can require few minutes to preload or warm up. You can allow hibernation for your EBS-backed instances at start. You can then pause and restart your EBS-backed EC2 instances via AWS Management Console, EC2 Instance Hibernation is now available in the US East (N. Virginia, Ohio), US West (N. California, Oregon), Canada (Central), South America (Sao Paulo), Asia Pacific (Mumbai, Seoul, Singapore, Sydney, Tokyo), and EU (Frankfurt, London, Ireland, Paris) Regions.To know more on this feature for your EC2 instances, refer FAQs or documentation
