A company needs to connect its on-premises data center to a Google Cloud Virtual Private Cloud (VPC) to support a steady daily transfer requirement of 1.5 Gbps. The connectivity solution must support high availability with a 99.99% Service Level Agreement (SLA) while minimizing overall infrastructure costs. Which hybrid connectivity architecture should you recommend?
- Configure an HA VPN deployment with two active-active IPsec tunnels operating over an Internet connection.Answer
- BProvision a 10 Gbps Dedicated Interconnect connection between the on-premises router and Google Cloud.
- CEstablish VPC Network Peering directly between the on-premises network and the Google Cloud VPC.
- DDeploy a Google Kubernetes Engine (GKE) cluster hosting self-managed IPsec gateway pods across two zones.
Answer
The optimal solution is to configure an HA VPN deployment with two active-active IPsec tunnels, meeting the 1.5 Gbps requirement and 99.99% SLA at minimal cost.
Google Cloud HA VPN provides up to 3 Gbps bandwidth per tunnel and guarantees a 99.99% availability SLA when properly configured with redundant tunnels across topological pairs. Because the throughput requirement is 1.5 Gbps, HA VPN satisfies all availability and technical constraints while avoiding the high costs of Dedicated Interconnect.
