Answer: Provision a Partner Interconnect through your ISP.
Given the requirements for direct connectivity using RFC 1918 address space, the need for handling bursts up to 1.5 Gbps, and the desire to minimize cost and complexity, the best solution is to provision a Partner Interconnect through your ISP. This option leverages the existing partnership with the ISP, provides the necessary bandwidth, and avoids the limitations and performance issues of VPN connections. Dedicated Interconnect, while offering high bandwidth, would introduce unnecessary complexity and cost. Creating multiple VPN tunnels or using network compression does not reliably address the bandwidth or packet loss issues and would add complexity.

Your team is building an on-premises web application that needs direct RFC 1918 connectivity to GCP Compute Engine instances. Given these requirements:
✑ Your ISP is a Google Partner Interconnect provider.
✑ Your on-premises VPN device has 10 Gbps internet uplink/downlink capacity.
✑ A test VPN connection to GCP achieves only 500 Mbps max due to packet loss.
✑ Most traffic flows from GCP to on-premises.
✑ The application may burst to 1.5 Gbps during peak Interconnect transfers.
✑ The solution should minimize cost and complexity.
What connectivity solution should you implement?
A
Provision a Partner Interconnect through your ISP.
B
Provision a Dedicated Interconnect instead of a VPN.
C
Create multiple VPN tunnels to account for the packet losses, and increase bandwidth using ECMP.
D
Use network compression over your VPN to increase the amount of data you can send over your VPN.
