EC2 hibernate와 spot instance

EC2 hibernate를 하면 RAM의 내용을 EBS로 저장할 수 있으니까 root volume에 저장된다는데?, 그럼 스팟 인스턴스로 대규모 계산을 할 때 그 내용을 저장해도 되는건가..? 스팟 인스턴스랑 같이 쓰일 수 있나?

 

root volume이 instance store 말하는게 아니었어. ㅎ

Hibernate interrupted Spot Instances - Amazon Elastic Compute Cloud

When Amazon EC2 hibernates a Spot Instance, the following occurs:

• When the instance receives a signal from Amazon EC2, the agent prompts the operating system to hibernate. If the agent is not installed, or the underlying operating system doesn't support hibernation, or there isn't enough volume space to save the instance memory, hibernation fails and Amazon EC2 stops the instance instead.
• The instance memory (RAM) is preserved on the root volume.
• The EBS volumes and private IP addresses of the instance are preserved.
• Instance store volumes and public IP addresses, other than Elastic IP addresses, are not preserved.
