When operating in disconnected or limited-connectivity environments, such as ships at sea, AWS recommends using AWS Snowball Edge devices to host local compute and storage workloads. Snowball Edge supports Amazon EC2 instances and AWS IoT Greengrass, and can run Amazon EKS Anywhere for local Kubernetes cluster deployments.
From AWS Documentation:
“You can use AWS Snowball Edge devices to run compute-intensive applications in remote or disconnected locations. Snowball Edge devices support running Amazon EC2 instances and Amazon EKS Anywhere clusters.”
(Source: AWS Snow Family – Developer Guide)
Why A is correct:
Snowball Edge provides local compute and storage even without internet connectivity.
Multiple Snowball Edge devices can be clustered together for high availability and failover.
Fully self-contained environment suitable for ships or field operations.
Why the others are incorrect:
B, C, D require network connectivity to AWS Regions or Zones (Local Zone, Outposts, Wavelength), which is not available at sea. These options cannot operate fully disconnected.
