Amazon EBS
Amazon Elastic Block Store (EBS) is a scalable, high-performance block storage service designed for use with Amazon EC2 instances in the AWS cloud. It provides persistent storage volumes that can be attached to EC2 instances, offering features like snapshots, encryption, and various volume types optimized for different workloads. EBS volumes behave like raw, unformatted block devices, allowing users to create file systems or run databases on them.
Developers should use Amazon EBS when they need durable, low-latency storage for applications running on EC2 instances, such as databases, enterprise applications, or boot volumes. It is essential for scenarios requiring data persistence beyond the lifecycle of an instance, like transactional systems or data analytics, and offers flexibility with features like snapshots for backups and the ability to resize volumes dynamically.
