Amazon Elastic Block Store (Amazon EBS) is a block-level storage service for Amazon Elastic Compute Cloud (EC2) instances. It provides persistent storage for data that is required by your EC2 instances, such as the operating system, applications, and other data that you want to store.
With Amazon EBS, you can create storage volumes that can be attached to and detached from EC2 instances as needed. This allows you to scale your storage capacity up or down as needed, and to use different types of storage volumes depending on your performance and cost requirements.
Amazon EBS provides several different types of storage volumes, including standard volumes, Provisioned IOPS (input/output operations per second) volumes, and Cold HDD (hard disk drive) volumes. Each type of volume is optimized for different workloads and use cases, such as high-performance databases, bursty workloads, or infrequent access to data.
In addition to the different types of volumes, Amazon EBS also provides several features to help you manage and protect your data. For example, you can use snapshotting to create backups of your EBS volumes, or use encryption to secure your data at rest and in transit.
