Kubernetes Platform Engineering

Implementing a production-grade Kubernetes platform with GitOps, service mesh, and comprehensive observability.

Kubernetes Platform Engineering

devops

Overview

We built a complete platform engineering solution that enables development teams to deploy applications safely and efficiently. The platform provides GitOps workflows, service mesh for traffic management, and comprehensive observability.

Challenges

  • 1Manual deployments causing inconsistencies across environments
  • 2No standardized way to deploy microservices
  • 3Limited visibility into application performance
  • 4Security concerns with container images
  • 5Difficult to manage secrets and configurations

Solutions

  • Kubernetes clusters on AWS EKS with Terraform
  • ArgoCD for GitOps-based continuous deployment
  • Istio service mesh for traffic management
  • Prometheus + Grafana for metrics and alerting
  • Loki for centralized logging
  • Vault for secrets management

Implementation

Infrastructure as Code

Created Terraform modules for VPC, EKS, and supporting infrastructure. Implemented multi-environment setup.

GitOps Pipeline

Deployed ArgoCD with ApplicationSets for automatic environment promotion. Integrated with GitHub Actions for CI.

Service Mesh

Configured Istio for mTLS, traffic splitting, and circuit breaking. Set up Kiali for visualization.

Observability Stack

Deployed Prometheus, Grafana, Loki, and Tempo. Created dashboards and alerting rules.
