WTG Case Study
WTG
End-to-end platform engineering transformation with Kubernetes, GitOps, and on-premise infrastructure modernization.
Project Overview
WTG required modernization of its legacy container platform and infrastructure. The solution involved migrating from Docker Swarm to Kubernetes, designing a multi-cluster on-premise architecture, and implementing a full DevOps platform including CI/CD, GitOps, observability, and security.
Industry
Context and Challenges
Client Requirements
Modern Kubernetes-based platform
Multi-environment clusters (Dev, QA, UAT, Prod)
Automated CI/CD and GitOps workflows
On-premise infrastructure design
Observability and monitoring stack
Security and policy enforcement
My Role
Architected and implemented a complete on-premise Kubernetes platform, including infrastructure design, CI/CD pipelines, GitOps deployment model, and security frameworks.
Strategy and Solution
Migrated workloads from Docker Swarm to Kubernetes (RKE2)
Designed multi-cluster architecture using Rancher
Implemented CI/CD using GitHub Actions
Enabled GitOps deployment using ArgoCD
Integrated observability, security, and storage solutions
