Cross-Cloud Interconnect for Google Cloud to AWS

What Cross-Cloud Interconnect is

Cross-Cloud Interconnect is a fully managed networking product that establishes direct, high-bandwidth, physical connections between Google Cloud and supported external cloud service providers (CSPs) such as Amazon Web Services (AWS), Microsoft Azure, and Oracle Cloud Infrastructure (OCI).

How it meets the requirements

• Dedicated High Bandwidth: Provides dedicated physical links at line-rate port capacities of 10 Gbps or 100 Gbps, allowing for high-throughput and low-latency data transfers between cloud environments.
• No Physical Hardware Management: Google provisions and manages the underlying physical cabling and cross-connect infrastructure directly at the edge demarcation point, eliminating the requirement for the customer to procure colocation space, run optical cables, or install and maintain physical routers.
• No Third-Party Intermediaries: Unlike Partner Interconnect, Cross-Cloud Interconnect does not require procuring network services or managing commercial contracts with third-party telecommunications or carrier providers.
• Service Level Agreement (SLA): Google provides a formal SLA (offering 99.9% or 99.99% availability topologies) covering the Google network all the way to the edge of the destination cloud service provider.

Key advantages and capabilities

• Reduced Operational Overhead: Significantly streamlines multicloud operations by avoiding complex multi-vendor contracts and colocation facilities.
• Private IP Communication: Facilitates private RFC 1918 communication across cloud VPCs using Cloud Router and Border Gateway Protocol (BGP) dynamic route advertisements.
• Encryption Options: Supports MACsec for Cloud Interconnect for high-speed Layer 2 point-to-point encryption.
• Centralized Management: Seamlessly integrates with Network Connectivity Center (NCC) as hybrid spokes.

Why this is optimal

Cross-Cloud Interconnect is purpose-built for enterprise multicloud topologies that require the speed and security of dedicated physical circuits without the infrastructure burden of maintaining colocation facilities or contracting third-party circuit brokers.
