Which solution offers the MOST reliable data transfer?
AWS DataSync over public internet
AWS DataSync over AWS Direct Connect
AWS Database Migration Service (AWS DMS) over public internet
AWS Database Migration Service (AWS DMS) over AWS Direct Connect
Explanations:
AWS DataSync over the public internet provides secure data transfer but may not be the most reliable or efficient for large, continuous data transfers like 10 TB per day. Public internet can be subject to network instability and throttling, potentially affecting transfer reliability.
AWS DataSync over AWS Direct Connect offers the most reliable and secure transfer. Direct Connect provides a dedicated, high-throughput connection with minimal latency, ensuring consistent and fast data transfer, which is critical for large volumes of sensitive data.
AWS DMS is typically used for database migrations, not for transferring large volumes of file-based data like JSON files. It is not designed for this use case and would not provide the necessary performance or reliability for large-scale file transfers.
AWS DMS over AWS Direct Connect is unnecessary for this use case. While Direct Connect would provide a reliable connection, DMS is not suitable for transferring file-based data, as it is specifically designed for database migrations, not large, structured data files like JSON.
