What is the MOST cost-effective solution?
Create a site-to-site VPN tunnel to an Amazon S3 bucket and transfer the files directly. Create a bucket policy to enforce a VPC endpoint.
Order 10 AWS Snowball appliances and select an S3 Glacier vault as the destination. Create a bucket policy to enforce a VPC endpoint.
Mount the network-attached file system to Amazon S3 and copy the files directly. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.
Order 10 AWS Snowball appliances and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.
Explanations:
A site-to-site VPN and direct transfer would likely saturate the low-bandwidth internet connection, making it inefficient for transferring large amounts of data like 750 TB.
Snowball is a good choice, but specifying S3 Glacier as the destination is incorrect. Snowball transfers to an S3 bucket first, not directly to Glacier.
Mounting the file system to S3 and transferring files directly would use the internet connection and could saturate the bandwidth, which is not ideal for large data transfers.
Using AWS Snowball to transfer data directly to an S3 bucket and then applying a lifecycle policy to transition the data to Glacier is the most cost-effective solution and avoids internet bandwidth issues.
From what I’ve seen, the answer is:
Order 10 AWS Snowball appliances and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.
