Which AWS service should a solutions architect use to meet these requirements?

Explanations:

AWS DataSync is designed for transferring data over the internet or through a VPC endpoint, but the existing Site-to-Site VPN connection is already 90% utilized. This could lead to potential performance issues, making it unsuitable for transferring 50 TB of data within the required timeframe.

AWS Direct Connect provides a dedicated network connection from the data center to AWS, which could facilitate the transfer of large amounts of data. However, since the question states that the company is relocating and needs to transfer data within 2 weeks, Direct Connect is typically more suited for ongoing connectivity rather than a one-time large data transfer, especially without the setup time needed.

AWS Snowball Edge Storage Optimized is specifically designed for transferring large amounts of data securely and efficiently. It can handle large data transfers, and it is suitable for transferring 50 TB of data within the 2-week timeframe by shipping physical devices to AWS for the data upload.

AWS Storage Gateway is used primarily for integrating on-premises environments with AWS cloud storage but is not optimized for transferring large amounts of data like 50 TB within a short period. Its primary function is ongoing data integration rather than bulk data transfer.
