Amazon EBS
#20 · Level 1 · Core services · StorageConcept
Section titled “Concept”Amazon EBS is the hard disk of an EC2 server. It is block storage, which means the server uses it just like its own regular disk. An EBS volume sits in a specific Availability Zone, and is attached to an EC2 instance in that same AZ. Even if you stop the server, the volume’s data stays, because the disk and the server are separate things. You can back up a volume by taking a Snapshot, which AWS stores safely.
