You must transfer 1 PB of data from on-prem to Google Cloud in a few hours over a secure link following Google best practices. What do you do?

For transferring 1 PB of data in a few hours, a high-bandwidth, dedicated connection is essential. Cloud Interconnect provides this secure, high-throughput link directly to Google Cloud, making it the most efficient option for large datasets. Storage Transfer Service is then ideal for managing the actual data transfer, offering features like data integrity checks, transfer scheduling, and parallelization, which are crucial for such a massive migration. Transfer Appliance is suitable for petabyte-scale transfers but involves shipping physical devices, which would take days or weeks, not "a few hours." Cloud VPN offers secure connectivity but typically has lower bandwidth limits than Cloud Interconnect, making it too slow for 1 PB in hours. gcloud compute scp is not designed for petabyte-scale transfers and lacks the robust features of Storage Transfer Service. Similarly, gsutil for 3 TB batches, while useful for smaller transfers, would be inefficient and difficult to manage for 1 PB within the tight time constraint.
