AWS EBS Volume

 EBS Volume

Volumes are AZ specific means the volumes created in an AZ can be attached to EC2 instances which get created in that AZ

To utilize volumes in other AZ you need to create the snapshot of the volume and then create a new volume in the different AZ from the snapshot and attach to the instance which are available in different AZ

Copy the snapshots from one Region to another Region

When we create a volume from a snapshot then the size of volume can be increased but cannot be decreased.

We can create a root volume by taking a snapshot of the root volume of any instance.
