  Cloud VPN with multiple tunnels for redundancy

  Why it's wrong here

  Cloud VPN establishes encrypted IPsec tunnels that carry traffic over the public internet, regardless of how many tunnels you deploy for redundancy. Even with multiple tunnels or higher bandwidth limits, the underlying path includes public internet infrastructure, so the compliance requirement is still violated. Additionally, Cloud VPN typically caps at ~3 Gbps aggregate throughput per gateway, which is insufficient for the required 10 Gbps capacity.

  Cloud Interconnect Dedicated (10 Gbps)

  Why this is correct

  Dedicated Interconnect provides a private, physical 10 Gbps (or 100 Gbps) connection from your on-premises network to Google at a Google edge co-location facility. Traffic traverses only Google's global network and never the public internet, which directly satisfies the compliance requirement. This option also comes with a 99.9% uptime SLA, making it the most robust and compliant choice for high-bandwidth, low-latency connectivity.

• ✗

  Partner Interconnect via a carrier partner

  Why it's wrong here

  Partner Interconnect relies on a third-party service provider to extend connectivity from your on-premises network to Google, which means traffic may traverse the provider's shared infrastructure rather than a direct Google-managed link. While it avoids the public internet, it does not meet the same level of isolation and directness as Dedicated Interconnect, and it often requires a carrier agreement and may have variable latency or performance. For a compliance mandate that emphasizes a direct, private circuit, Partner Interconnect is less suitable than Dedicated Interconnect.

• ✗

  Cloud Router with BGP peering over the public internet

  Why it's wrong here

  Cloud Router is a BGP routing component that exchanges routes dynamically between your VPC and on-premises network, but it does not create any underlying transport. If you attempt to peer BGP over the public internet, the routing protocol itself still runs over public IP space, which violates the stated requirement that no internet-based connectivity be used. Moreover, public BGP sessions are not encrypted natively and expose routing information, making this both a compliance and security failure.
