Anthos Hybrid Environment Reference Architecture

This document is a reference architecture that outlines the deployment of Anthos in a hybrid environment. It addresses the challenges organizations face when managing multiple Kubernetes clusters across different environments, including on-premises data centers and cloud platforms. The architecture provides guidance on how to modernize applications and infrastructure, create a unified cloud operating model, and enforce consistent governance and security. It details the components of Anthos, including Google Cloud services and on-premises elements, and explains how these components work together to manage logging, monitoring, and configuration. The document also describes the importance of separating administrative and user clusters for security and operational efficiency, and it discusses the benefits of using multiple sites for disaster recovery and testing. Additionally, it provides high-level examples of reference deployments and design considerations for implementing a complete Anthos hybrid environment.
