A team needs to load 100 TB of on-premises data into Cloud Storage as quickly as possible, but only has 100 Mbps of internet bandwidth. Which option is BEST?
ARun a single `gsutil cp` over the 100 Mbps link and wait
BEmail the data to Google in batches of 100 MB
CUse Google Transfer Appliance (a physical device shipped to the customer, filled, and shipped back to Google)
DConvert the data into BigQuery rows first, then network upload as SQL
Answer & Solution
Correct answer: C. Use Google Transfer Appliance (a physical device shipped to the customer, filled, and shipped back to Google)
At 100 TB over 100 Mbps the wire transfer would take roughly 90+ days. Transfer Appliance physically ships the data — ideal at this volume/bandwidth ratio. Email and BigQuery-as-row tricks don't apply; the gsutil approach is what we're trying to avoid.
