Storage

Amazon Elastic Block Store (Amazon EBS)

Block storage volumes for supported EC2 workloads.

Key points

  • Relevant only as an existing application storage surface in this lane.
  • Server, operating-system, and storage architecture administration are outside DVA-C02.

Best-known use cases

  • Persistent block storage attached to an EC2 application instance.

What candidates often confuse it with

  • EBS provides block volumes; EFS provides shared file storage; S3 provides object storage.

Key takeaway

Recognize EBS as EC2 block storage without studying volume administration at depth.
