A comprehensive DevOps implementation showcasing modern cloud infrastructure, CI/CD pipelines, and Infrastructure as Code (IaC) practices for a three-tier web application on AWS.
This project demonstrates enterprise-grade DevOps practices by implementing a complete cloud infrastructure and deployment pipeline for a three-tier web application. While the application code (React frontend and Spring Boot backend) is sourced from the open-source community, all DevOps engineering, infrastructure design, and automation is original work.
- Complete AWS Infrastructure - Terraform modules for scalable, secure cloud architecture
- CI/CD Pipelines - Automated testing, building, and deployment workflows
- Infrastructure as Code - Modular, reusable Terraform configurations
- Security & Compliance - Best practices for cloud security and monitoring
- Multi-Environment Support - Dev/staging/production environment management
- Frontend Tier: React SPA served via CloudFront CDN + S3
- Backend Tier: Spring Boot API on ECS Fargate with Application Load Balancer
- Data Tier: MySQL RDS with automated backups and scaling
- Networking: VPC with public/private subnets across multiple AZs
- Security: SSL/TLS encryption, security groups, and IAM roles
- DNS: Route 53 hosted zone with custom domain management

Frontend:
Backend:
Frontend CD: Automated deployment pipeline that uploads build artifacts to S3 (requires manual approval) on successful push to the main branch from /src/frontend. The React application is built, optimized, and deployed to S3, then distributed globally via CloudFront CDN. Requires manual approval for production deployment.
Backend CD: Automated deployment pipeline that deploys containerized Spring Boot application to ECS Fargate (requires manual approval) on every successful push to the main branch from /src/backend. Uses rolling updates for zero-downtime deployments with health checks and automatic rollback capabilities.
✅ Infrastructure as Code - 100% Terraform-managed infrastructure
✅ GitOps Workflow - Git-based infrastructure and deployment management
✅ Multi-Environment - Separate dev/staging/production environments
✅ Security First - SSL/TLS, security groups, least privilege access
✅ Monitoring & Logging - CloudWatch integration and alerting
✅ Cost Optimization - Spot instances, autoscaling, resource tagging
✅ Disaster Recovery - Multi-AZ deployment, automated backups

This project focuses on DevOps practices and infrastructure. Contributions welcome for:
- Infrastructure improvements and optimizations
- CI/CD pipeline enhancements
- Security and compliance features
- Documentation and best practices
- Application Code: Frontend (React) and Backend (Spring Boot) applications are sourced from the open-source community
- DevOps Implementation: All infrastructure, CI/CD, and deployment automation is original work
- AWS Community: For excellent documentation and best practices
For questions about the DevOps implementation, infrastructure design, or deployment processes, please open an issue or reach out directly.
Note: This project demonstrates DevOps engineering capabilities including Infrastructure as Code, CI/CD pipeline design, cloud architecture, and automation. The application code serves as a vehicle to showcase these DevOps practices in a real-world scenario.
