Amazon Elastic Block Store (EBS)
Amazon Elastic Block Store (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, offering high availability and durability. Amazon EBS
volumes offer the consistent and low- latency performance needed to run your workloads. With Amazon EBS,
you can scale your usage up or down within minutes all while paying a low price for only what you provision.
