A company seeks a storage solution for its application.The solution must be highly available and scalable.The solution also must function as a file system be mountable by multiple Linux instances in AWS and on premises through native protocols, and have no minimum size requirements.The company has set up a Site-to-Site VPN for access from its on-premises network to its VPC.

Which storage solution meets these requirements?

Amazon FSx Multi-AZ deployments

Amazon Elastic Block Store (Amazon EBS) Multi-Attach volumes

Amazon Elastic File System (Amazon EFS) with multiple mount targets

Amazon Elastic File System (Amazon EFS) with a single mount target and multiple access points

Explanations:

Amazon FSx Multi-AZ deployments provide high availability, but FSx is generally optimized for Windows applications or specialized workloads and may not be natively mountable on Linux instances both in AWS and on-premises.

Amazon EBS Multi-Attach volumes allow multiple EC2 instances to access the same block storage, but they cannot be mounted as a shared file system across multiple Linux instances or accessed over a network.

Amazon EFS with multiple mount targets provides a scalable, highly available file system that can be mounted on multiple Linux instances both in AWS and on-premises using the NFS protocol, meeting all specified requirements.

Amazon EFS with a single mount target and multiple access points does not meet the requirement for high availability and scalability across multiple availability zones and instances.
