ME News message. On April 5 (UTC+8), Google Cloud recently published a technical article introducing a private connectivity reference architecture designed for generative AI applications with retrieval-augmented generation (RAG) capabilities. The architecture is suitable for scenarios where system communications must use private IP addresses and cannot go through the public internet. Its design uses a regional model and includes an external network and the Google Cloud environment, with the latter consisting of a routing project, a shared VPC host project, and three dedicated service projects. The architecture integrates key services such as Cloud Interconnect/Cloud VPN, the Network Connectivity Center, Cloud Router, Private Service Connect, shared VPC, Cloud Armor, Application Load Balancers, and VPC Service Controls. The article describes in detail three core traffic paths: the RAG data population flow, the inference flow, and the management and routing flow. The goal is to provide a secure and reliable infrastructure for enterprise AI workloads through end-to-end private connectivity and layered security controls. (Source: InFoQ)
