Network design: mobile/web apps remain on-premises; analytics run in GCP. Move 900 TB archived CSVs once, then ingest 10 TB/day. You have a 100 Mbps internet link. What actions meet the needs?

The correct option addresses both the large one-time data transfer and the ongoing daily ingestion efficiently. Transfer Appliance is ideal for moving 900 TB of archived data, as a 100 Mbps link would take years. For the 10 TB/day ongoing ingestion, Dedicated Interconnect or Direct Peering provides the necessary bandwidth and reliability, significantly outperforming the existing 100 Mbps internet link. Compressing and uploading all data with gsutil -m over a 100 Mbps link is too slow for both the initial archive and the daily ingestion. Using a single Cloud VPN over the internet, even with compression, would still be constrained by the 100 Mbps link for 10 TB/day, leading to significant delays and potential bottlenecks. While Cloud VPN adds security, it doesn't solve the bandwidth limitation for large daily transfers.
