Let's say I have a linux instance in Amazon and I save everything in the EBS. I only need to use the instance a few times in a month therefore, normally I will "stop" the instance and "start" it when I need to use it. Beside this, I wonder if there is any further way to save more cost? The EBS is allocated all the time - can that be moved into s3 and put back to EBS when I need to use the instance?
By default, the EBS comes with 8Gb of stores. It was created by the image instance. Let say we already put data in the EBS. Can the EBS trim the size smaller from 8gb to 1gb, so I save cost?
