EBS

Elastic Block Store (EBS)

• Is a scalable, high-performance, block-storage service for use with Amazon EC2 instances. (It's specifically for attaching to servers that are launched with Amazon EC2)

• With EBS, you can scale your usage up or down within minutes.

• Has high-durability (99.999%), including replication within AZs.

  • Each EBS volume is automatically replicated within its AZ to protect from component failure.

• You can encrypt your block storage without needing to build, maintain and secure your own key management infrastructure.

• Protect block-storage with EBS Snapshots, that can be used to enable disaster recovery, migrate data across Regions, and improve backup compliance.

  • AWS further simplifies the lifecycle management of your snapshots integrating with Amazon Data Lifecycle Manager.

    • Creates Policies to automate tasks like creation, deletion, retention and sharing of snapshots.
