Elastic Block Store (EBS) provides persistent block storage volumes for use with EC2 instances in the AWS Cloud.
Each EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability.
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.
EBS volumes are particularly well-suited for use as the primary storage for file systems, databases, or for any applications that require fine granular updates and access to raw, unformatted, block-level storage.
EBS is well suited to both a. database-style applications that rely on random reads and writes. b. applications that perform long, continuous reads and writes.
