I'm planning to bring up a few EC2 Spot Instances in the near future but, before I do, I have a couple of questions that I couldn't find answers to in the documentation.
I was curious if it was possible for a spot instance to reanimate after it's terminated. I understand once a instance is dead, it's dead forever, but if you keep the EBS volume from terminating and keep the lease on the IP address (reserving it), could you dynamically reassign these to the newly spawned instance?
Thanks for any help you could provide.
Edit: S3 would be great if it supported incremental file changes but, if I use that, then the entire file this instance is working on would be reuploaded every time and that just wouldn't work. Furthermore, this isn't a queueable task. S3 would be great for data backup and restoration for periods when the spot instance is terminated. Does Amazon give the instance the opportunity to do this? (I only need to move 1GB at a time or less to S3 if dynamic EBS is out of the question.)
