Overview
Amazon EBS provides persistent, block-level storage volumes for use with Amazon EC2 instances in the AWS cloud. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure. Amazon EBS volumes offer the consistent and low-latency performance.
EBS is not attached to the instance, the life cycle of storage is separated from the life cycle of the insurance. EBS chops the data into blocks and stores it across a number of physical disks. Volumes can be detached from an EC2 instance and attached to a different instance. A volume can be attached to only one instance.
