Implementation and Management of a Kubernetes Cluster (EKS) for a Critical E-Commerce Platform
Deployment and Management of Kubernetes (EKS): Designed and maintained a robust EKS cluster to host a high-traffic e-commerce platform, ensuring scalability and high availability.
Custom Helm Chart Development: Created Helm Charts for application services, including backend, frontend, and database, ensuring seamless deployments and version control.
Network Performance Optimization: Implemented Nginx Ingress Controller to manage HTTP/HTTPS traffic efficiently and used ExternalDNS for dynamic DNS management.
Security Enhancements:
Enforced Network Policies to control inter-service communication and implemented IAM Roles for Service Accounts (IRSA) for fine-grained access control, ensuring strict workload isolation.
Advanced Monitoring & Observability:
Integrated Prometheus for collecting real-time metrics and Grafana for performance visualization, enabling proactive issue resolution.
Key Achievements:
✅ 40% Reduction in Production Incidents:

Implemented liveness and readiness probes to monitor container health, enabling automatic restarts of failing services.
✅ 30% Improvement in Application Performance:

Optimized HTTP/HTTPS routing and enabled caching via AWS CloudFront, significantly reducing page load latency.
This implementation ensured a resilient, secure, and high-performance cloud infrastructure, delivering a seamless user experience for the e-commerce platform. 🚀
