A mid-sized retail company is designing private connectivity from its on-premises data center to Google Cloud. Their analysis shows steady-state throughput of about 3 Gbps to VPCs, with occasional bursts. They do not have a physical presence in any Google colocation facility and want to avoid the cost and lead time of provisioning cross-connects in a Google peering location. Availability targets are moderate (99.9%), and they prefer to onboard within a few weeks. Which connectivity model should you recommend?
