Cloud Interconnect offers Dedicated Interconnect and Partner Interconnect options, enabling enterprises to establish high-bandwidth, low-latency, private connections to Google Cloud. Cloud VPN provides encrypted tunnels over the public internet but is limited in bandwidth and may introduce latency. Cloud Router enables dynamic routing for VPN or Interconnect connections, but does not establish the connection itself. Cloud NAT provides outbound internet access for private instances but is unrelated to dedicated connectivity. Dedicated Interconnect allows organizations to connect their on-premises network to Google Cloud using physical fiber connections at colocation facilities, supporting bandwidths of 10 Gbps or higher, while Partner Interconnect allows connectivity through service providers. Interconnect ensures predictable performance, high availability, and low latency for mission-critical workloads such as databases, analytics, and real-time applications. IAM and network policies enforce security and access control, and monitoring through Cloud Monitoring provides visibility into traffic, utilization, and performance. Cloud Interconnect supports redundant connections for resilience and failover, ensuring operational continuity. Enterprises can implement hybrid cloud architectures, extending on-premises networks securely into Google Cloud. Integration with VPC networks, Cloud Router, and firewall policies allows centralized management and routing control. Interconnect provides scalable bandwidth options to meet the requirements of large enterprises, reducing the dependency on the internet and mitigating performance variability. By leveraging Cloud Interconnect, organizations achieve dedicated, secure, and high-performance connectivity between on-premises infrastructure and Google Cloud, supporting latency-sensitive and high-throughput applications reliably. It ensures operational efficiency, predictable network performance, and robust hybrid cloud architectures. Cloud Interconnect is the preferred solution for enterprises requiring private, high-bandwidth connections to Google Cloud, enabling seamless integration, disaster recovery, and operational resilience for mission-critical workloads.
