A company needs to migrate an on-premises SFTP site to AWS. The SFTP site currently runs on a Linux VM. Uploaded files are made available to downstream applications through an NFS share. As part of the migration to AWS, a solutions architect must implement high availability. The solution must provide external vendors with a set of static public IP addresses that the vendors can allow. The company has set up an AWS Direct Connect connection between its on-premises data center and its VPC. Which solution will meet these requirements with the LEAST operational overhead?
