A logistics company is migrating its containerized supply-chain application to AWS. The architecture requires two types of storage: first, a persistent, high-performance block storage volume attached to a single Amazon EC2 instance running a transaction database; second, a shared file storage system that can be mounted simultaneously by multiple EC2 instances across different Availability Zones to process configuration templates. Which two AWS storage services should the company select to meet these requirements?
- Amazon Elastic Block Store (Amazon EBS)Answer
- Amazon Elastic File System (Amazon EFS)Answer
- CAmazon Simple Storage Service (Amazon S3)
- DAmazon EC2 Instance Store
- EAmazon S3 Glacier Flexible Retrieval
Answer
Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS)
The correct choices are Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS). Amazon EBS provides persistent block-level storage designed for EC2 instances, making it the correct choice for a database root volume or transaction log. Amazon EFS provides a fully managed shared file system that can be mounted concurrently by multiple EC2 instances across different Availability Zones, satisfying the requirement for shared configuration templates.
