Amazon Elastic Block Store
EC2 Block Storage Volumes
Amazon Elastic Block Store (Amazon EBS) provides persistent block storage for use with Amazon EC2 instances. 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.
