A development EC2 instance is used only during working hours.
Preserve its memory state while stopped so work can resume quickly.
Which feature is most appropriate?
Use EC2 hibernation to save the in-memory state to the EBS root volume when the instance stops.
Detailed explanation
Hibernation saves memory to the EBS root volume and restores it when the instance resumes.

Foundation review
State preservation
Hibernation resumes the operating-system and application state rather than booting from scratch.
Idle capacity
Keeping an instance running avoids resume work but pays for unused compute time.
