This guide details the deployment of a production-grade Google Kubernetes Engine (GKE) platform utilizing established patterns from extensive Google Cloud Platform (GCP) enterprise deployments. It outlines the prerequisites necessary for implementation, including a completed Kubernetes Readiness Assessment, defined GCP organization and project structure, approved network and security policies, documented IAM model and requirements, and confirmed platform team availability. The document describes the deployment process, which is divided into three main phases: Foundation & Infrastructure, Platform Services & Integration, and Validation & Optimization, each lasting four weeks. Key technical outcomes include achieving a high availability configuration, validating multi-regional resilience, and establishing security controls aligned with Google Cloud standards. Deliverables from this deployment include as-built GKE architecture documentation, Infrastructure-as-Code repositories, security and compliance validation reports, and operational runbooks.
