What is a block storage volume?
A block storage volume operates in the same way that a hard drive does. It can be used to store any type of file or even to install an entire operating system.
EBS volumes are placed in an availability zone and automatically replicated to protect data loss in the event of a single component failure.
However, because they are only replicated across a single availability zone, you may lose data if the entire availability zone fails, which is extremely unlikely.
