Amazon Elastic Block Store (Amazon EBS) is a high-performance, persistent block storage service designed for use with Amazon Elastic Compute Cloud (EC2). Amazon EBS works like a virtual hard drive for EC2 instances. It is designed for workloads that require low latency, high IOPS, and durable storage.

• Persistent storage that remains available even after an EC2 instance stops or terminates.
• Delivers low latency and high IOPS for transactional workloads.
• Automatically replicates data within the same Availability Zone.
• Supports Elastic Volumes for dynamic resizing and performance tuning
