Amazon EBS

Amazon EBS is a high-performance block storage service designed for use with EC2 for all types of workloads at any scale. A broad range of workloads, such as database applications, containerized applications, and big data analytics engines, can benefit from EBS’s reliable, scalable, and secure storage solutions. EBS volumes are automatically replicated within their Availability Zone to protect your data from component failure, offering high availability and durability. Unlike S3, EBS stores data in blocks rather than files, allowing it to be used to host an operating system that runs your EC2 instance. You can consider EBS to be like a hard disk drive within your own computer.
