Implementation Guide

Overview

This document summarizes the phase-by-phase implementation of the Production-Grade Cloud-Native CI/CD Platform.

The project was built incrementally to ensure infrastructure stability, deployment safety, observability, scalability, and operational reliability.

Implementation Roadmap

Phase 0  → Repository Architecture Lock
Phase 1  → React Application Setup
Phase 2  → Dockerization
Phase 3  → VPC Foundation
Phase 4  → IAM & Security Groups
Phase 5  → Amazon ECR
Phase 6  → Amazon ECS Fargate
Phase 7  → Application Load Balancer
Phase 8  → Blue-Green Deployment
Phase 9  → Jenkins CI/CD
Phase 10 → CloudWatch Monitoring
Phase 11 → SNS Alerting
Phase 12 → ECS Auto Scaling
Phase 13 → CloudFront CDN
Phase 14 → Validation & Testing
