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 lowlatency 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.
