Which solution meets these requirements?
Use AWS Transfer for SFTP to transfer files into and out of Amazon S3.
Use AWS Snowball Edge for local storage and large-scale data transfers.
Use Amazon FSx to store and transfer files to make them available remotely.
Use AWS Storage Gateway to create a volume gateway to store and transfer files to Amazon S3.
Explanations:
AWS Transfer for SFTP provides a fully managed service for transferring files into and out of Amazon S3, making it accessible for employees, remote workers, and external partners. It supports secure file transfers and integrates well with existing S3 workflows.
AWS Snowball Edge is designed for large-scale data transfers and edge computing, but it is not suitable for day-to-day file exchange needs. It requires physical hardware and is not a fully managed service for ongoing file transfers.
Amazon FSx provides a managed file system but is primarily intended for scenarios requiring file shares within VPCs. It does not inherently support secure file transfers or external access as seamlessly as AWS Transfer for SFTP.
AWS Storage Gateway can facilitate access to S3 through a volume gateway, but it is more complex than necessary for simple file exchanges. It is designed for hybrid cloud storage but does not specifically cater to the straightforward file exchange use case required.
As far as I can tell, the answer is:
Use AWS Transfer for SFTP to transfer files into and out of Amazon S3.
From my point of view, the answer is:
Use AWS Transfer for SFTP to transfer files into and out of Amazon S3.
