A company is migrating a stateful application to AWS. The application uses local storage for temporary data that must survive instance restarts but not region failures. Which storage solution should the company use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Instance Store
Instance Store provides ephemeral block storage that persists across instance reboots but is lost if the instance is stopped or terminated. This matches the requirement for temporary data that survives restarts but not region failures. Option A (Amazon EBS) survives stops, which is unnecessary. Option C (Amazon S3) is object storage, not temporary local storage. Option D (Amazon EFS) is a network file system, not local storage.
