Amazon Elastic Block Store (EBS) enables a single Amazon EC2 instance to attach to one or more highly available, highly reliable storage volumes of up to 1 TB of data each. Once attached, applications on a single Amazon EC2 instance can read or write from the Amazon EBS volume similar to a disk drive. With Amazon EBS, an Amazon EC2 instance can now be terminated without losing the data that resides on the Amazon EBS volume. One use case involves running a relational database within an Amazon EC2 instance, but maintaining the data within an Amazon EBS volume.
