Amazon EC2 now supports Hibernation for Ubuntu 20.04 LTS operating system. Hibernation allows you to pause your EC2 Instances and resume them at a later time, rather than fully terminating and restarting them. Resuming your instance lets your applications continue from where they left off so that you don’t have to restart your OS and application from scratch. Hibernation is useful for cases where rebuilding application state is time-consuming (e.g., developer desktops) or an application’s start-up steps can be prepared in advance of a scale-out.
For Ubuntu 20.04 LTS, Hibernation is supported for On-Demand Instances running on C3, C4, C5, C5d, I3, M3, M4, M5, M5a, M5ad, M5d, R3, R4, R5, R5a, R5ad, R5d, T2, T3, and T3a with up to 150 GB of RAM.
