01 / PROBLEM & CONTEXT

Modernizing healthcare workloads for scale and compliance.

Legacy Cloud Functions architectures lacked the operational scalability, fine-grained networking, and unified observability needed for enterprise medical imaging and AI services.

Workloads required strict adherence to GxP and 21 CFR Part 11 compliance standards, necessitating reproducible multi-environment infrastructure, rigorous audit logging, automated vulnerability scanning, and centralized identity federation.

02 / MY ROLE & OWNERSHIP

GKE Platform Modernization & Security Lead

Led the infrastructure design and migration from legacy Cloud Functions to production-grade GKE clusters across Dev, UAT, and Production environments.

Enforced GxP compliance standards, integrated centralized Cloud Monitoring and alerts, and built reusable Terraform and Helm deployment pipelines.

Architected GKE-based multi-environment platform with Terraform, Helm, and GitOps principles
Migrated legacy Cloud Functions services to Kubernetes clusters, improving scalability and maintainability
Integrated Cloud Monitoring and Alerts for centralized observability and operational monitoring
Supported Australia region for GKE workloads, bringing mission-critical AI services online across regions
Implemented Keycloak for secure authentication, authorization, and SSO integration
Standardized Dev, UAT, and Production infrastructure through automated deployment pipelines
Implemented comprehensive security controls with IAM, RBAC, SonarQube, and Nessus vulnerability scanning
04 / APPROACH & ARCHITECTURE

Reproducible, compliant infrastructure as code.

01 / GXP GOVERNANCE

Auditable delivery pipelines

Standardized GitOps releases with automated vulnerability scanning (Nessus), static analysis (SonarQube), and controlled release approvals.

02 / MULTI-ENV IAC

Zero-drift environments

Declarative Terraform modules and Helm releases ensure Dev, UAT, and Production environments remain consistent and reproducible.

03 / OBSERVABILITY & IDENTITY

Centralized telemetry and SSO

Google Cloud Monitoring metrics with automated alert triggers, unified with Keycloak authentication and granular Kubernetes RBAC.

Migration from serverless to GKE

Transitioned compute-intensive medical imaging microservices to dedicated GKE clusters, improving memory headroom and request throughput.

Multi-region expansion

Deployed and supported GKE clusters across global regions, including launching Australia region infrastructure for healthcare AI services.

Identity federation with Keycloak

Configured centralized SSO, user management, and service-to-service authentication integrated with Kubernetes RBAC.

05 / KEY DECISIONS & TRADE-OFFS

The choices behind the architecture.

GKE clusters over Cloud Functions
Allowed custom container runtimes, advanced networking, and sustained medical imaging compute execution.
Introduced Kubernetes cluster lifecycle and node pool management responsibilities.
Modular Terraform architecture
Enabled consistent multi-environment deployments across Dev, UAT, and Production.
Required strict state file locking and workspace separation across environments.
Keycloak SSO integration
Provided unified identity governance and Part 11 access audit trails across microservices.
Required configuring and maintaining Keycloak realm definitions and token lifecycle policies.
06 / RESULT
20+ GKE Clusters
Standardized across Dev, UAT, Prod

A modernized, compliant foundation for medical AI workloads.

Successfully migrated legacy workloads to Kubernetes, achieved GxP compliance posture with automated Nessus scanning, and brought multi-region clusters online.

Managed 20+ GKE clusters across multiple environments
Seamless migration from Cloud Functions to Kubernetes
Standardized multi-environment IaC with Terraform and Helm
Automated Nessus vulnerability and SonarQube code scanning
Expanded platform reach to Australia region
More systems. Same intent.
