Private VPC Connectivity with Dedicated Interconnect

What Dedicated Interconnect with Private Google Access is

Dedicated Interconnect provides a direct physical circuit (10 Gbps or 100 Gbps) between an on-premises network and Google's private backbone network at a colocation facility. When combined with Cloud Router for dynamic Border Gateway Protocol (BGP) route exchange and Private Google Access for on-premises hosts, on-premises workloads can securely communicate with Google Cloud resources and Google APIs without using public internet transit.

How it meets the requirements

• Throughput and Latency: Dedicated Interconnect provides enterprise-grade, high-capacity physical links (10 Gbps or 100 Gbps) that deliver consistent high throughput and minimal latency compared to internet-based tunnels.
• Security and Privacy: All network packets flow directly over private physical circuits into the Google Cloud VPC network, ensuring zero exposure to the public internet.
• Google Services Access: Configuring Private Google Access for on-premises hosts allows migration utilities and on-premises agents to reach Google APIs (such as Cloud Storage and BigQuery) over the private interconnect using internal routing.
• Cost Optimization: Network egress rates across Cloud Interconnect are significantly lower than standard public internet egress rates, optimizing overall data transfer costs during verification and replication cycles.

Key advantages and capabilities

• Scalable Bandwidth: Accommodates multi-terabyte and petabyte-scale data transfers with 10 Gbps or 100 Gbps Ethernet circuits.
• Dynamic Route Propagation: Cloud Router automatically manages custom dynamic routes, ensuring seamless failover and route propagation across regional subnets.
• High Availability SLAs: Supports up to a 99.99% availability SLA when deployed across dual Google Cloud regions and distinct colocation facilities.
• Private Service Consumption: Grants private API reachability without requiring public IP addressing on source database servers.

Why this is optimal

This approach directly satisfies the dual demands of massive transfer volume and stringent enterprise security. Unlike VPNs or internet peering, Dedicated Interconnect establishes dedicated physical capacity with lower egress charges, deterministic latency, and native private routing to Google Cloud services.
