You are deploying an application to Google Cloud. The application is part of a system. The application in Google Cloud must communicate over a private network with applications in a non-Google Cloud environment. The expected average throughput is 200 kbps. The business requires: ✑ as close to 100% system availability as possible ✑ cost optimization You need to design the connectivity between the locations to meet the business requirements. What should you provision?

An HA Cloud VPN gateway with two tunnels provides high availability by using two interfaces, each with its own external IP address, ensuring redundancy and meeting the "as close to 100% system availability as possible" requirement. The 200 kbps throughput is well within Cloud VPN's capabilities (up to 3 Gbps per tunnel). This option is also cost-effective compared to dedicated interconnects, aligning with "cost optimization." The other options are less suitable: Two Classic Cloud VPN gateways are more complex and expensive than a single HA VPN and don't inherently offer better availability for this scenario. Two HA Cloud VPN gateways are overkill for the throughput and significantly more expensive than a single HA VPN, failing on cost optimization. A single Cloud VPN gateway (implying a Classic VPN with one tunnel) lacks the redundancy for high availability.
