Elastic Block Store (EBS)

Amazon EBS provides block storage volumes for EC2. A volume can act as a root or additional disk depending on configuration.

Why it matters

Applications need storage that behaves like a disk rather than object storage.

How it works

Create/attach volume → format/mount when required → store data → snapshot when appropriate → manage lifecycle.

Real-world example: An application server can use EBS for operating-system files and application data that require block-storage semantics.

Core Concept

EBS volumes provide block storage that can be attached to EC2 instances.

Choose volume type and size according to performance, durability and cost requirements.

Key idea

Choose volume type and size according to performance, durability and cost requirements.

Real-world example

Use a realistic cloud workload and focus on the responsibility of this AWS service.

User → AWS service → application → data / response

Choose the service that matches the responsibility instead of forcing every workload into one resource.

# Conceptual workflow aws-service --resource example # Verify configuration → test → monitor → clean up
Practice tip: Build the smallest possible lab, verify the result, then remove resources you no longer need.
