Elastic Block Store (EBS)

Elastic Block Store (EBS) is a storage service from Amazon Web Services that provides persistent, high-performance storage for virtual machines (called EC2 instances). Think of it as a virtual hard drive that you can attach, detach, and resize as needed. EBS stores data reliably and allows quick access, making it ideal for running applications, databases, and file systems in the cloud. It's designed to offer durability, scalability, and consistent performance, enabling users to manage storage resources flexibly without worrying about hardware limitations.
