The Elastic Block Store (EBS) functionality is accessed from the Amazon EC2 tab, and then via the Volumes link in the Navigation pane.
Elastic Block Store (EBS) is the disk storage system for AWS and operates similarly to an external Storage Area Network (SAN) in a typical data center. EBS is a system that enables EC2 instances to access disks, which are configured, created, and managed externally to each EC2 instance.
EBS disks can be created independently of an EC2 instance and can be moved between EC2 instances at will.
In fact, if EC2 is the engine of AWS, you could consider EBS to be the fuel tank, holding all the resources for applications running on EC2.
EBS disks are a powerful feature of AWS and hold persistent data. This means that any data stored on an EBS volume will persist after an EC2 instance has been stopped or terminated.
EBS disk is also faster than the instance disk associated with an EC2 running instance if the instance uses the S3 instance store...
