 - **Availability Zones:** EBS volumes are confined to a single Availability Zone, which may affect high availability and disaster recovery strategies. Kubernetes has implemented several mitigations for this limitation, and ECS likely has similar solutions.
 - **Scalability:** Requires manual provisioning and management of storage capacity, which can introduce operational complexity.

 Use **Amazon EBS** unless there is a good reason not to.
