What is the relationship between the state of an EC2 instance and its associated EBS volumes? How do EBS volumes behave in terms of attachment, detachment, and deletion in different EC2 instance states.

When the instance is running, the EBS volumes are attached and fully usable. If the instance is stopped, the volumes stay attached but are not in use ( still possible to detach them safely). During a reboot, the volumes stay attached and nothing change. When the instance is terminated, the root volume is deleted if the " Delete on termination " is enabled (but additional volume stay unless you choose to delete them). Volumes can be attached or detached when the instance is running or stopped but detaching while running should be done carefully to avoid data loss.
