A company is planning to migrate its on-premises SFTP site, which currently operates on a Linux VM, to AWS. The site's functionality includes making uploaded files accessible to downstream applications via an NFS share. To ensure high availability in the AWS environment and to meet the requirement of providing external vendors with static public IP addresses for security purposes, the company has established an AWS Direct Connect link between its on-premises data center and its VPC. A solutions architect is tasked with selecting a solution that minimizes operational overhead. Which of the following solutions best meets these criteria?
A
Deploy an AWS Transfer Family server with an internet-facing VPC endpoint, assigning an Elastic IP to each subnet. Configure the server to store files in an Amazon EFS system spanning multiple Availability Zones. Update the downstream applications to mount the EFS endpoint in place of the existing NFS share.
B
Set up an AWS Transfer Family server with a publicly accessible endpoint. Configure it to store files in an Amazon EFS system across multiple Availability Zones. Adjust the downstream applications to mount the EFS endpoint instead of the current NFS share.
C
Migrate the existing Linux VM to an Amazon EC2 instance using AWS Application Migration Service, and assign it an Elastic IP. Attach an Amazon EFS system to the EC2 instance and configure the SFTP server to use the EFS for file storage. Modify the downstream applications to mount the EFS endpoint in lieu of the NFS share.
D
Migrate the existing Linux VM to an AWS Transfer Family server using AWS Application Migration Service, and configure it with a publicly accessible endpoint. Set it up to store files in an Amazon FSx for Lustre system deployed across multiple Availability Zones. Update the downstream applications to mount the FSx for Lustre endpoint instead of the NFS share.
