🚀 Zero-Downtime Deployments on AWS EKS

Production-grade implementation of Blue-Green and Canary deployment strategies using Argo Rollouts on Amazon EKS.

📖 Overview

This project demonstrates two zero-downtime deployment patterns with comprehensive testing and monitoring:

• ��🟢 Blue-Green Deployment: Instant traffic cutover with immediate rollback capability
• 🕊️ Canary Deployment: Progressive traffic shifting (10% → 25% → 50% → 75% → 100%)

Key Results:

• ✅ 41,350 requests tested across both strategies
• ✅ 0 failures (100% success rate)
• ✅ True zero-downtime achieved
• ✅ Comprehensive monitoring with Prometheus & Grafana
