# Java Microservice Infrastructure
[]()
[]()
[](https://opensource.org/licenses/MIT)
[]()
A production-ready demonstration of modern DevOps practices featuring a Java Spring Boot microservice with complete CI/CD automation, infrastructure as code, and container orchestration.
## 🏗️ Architecture Overview
This project demonstrates a complete DevOps pipeline for a user management microservice, showcasing industry best practices for:
- **Continuous Integration/Continuous Deployment (CI/CD)**
- **Infrastructure as Code (IaC)**
- **Container Orchestration**
- **Monitoring and Observability**
- **Security and Compliance**
## 🚀 Technology Stack
| Category | Technologies |
|----------|-------------|
| **Application** | Java 17, Spring Boot 3.x, PostgreSQL |
| **Containerization** | Docker, Docker Compose |
| **CI/CD** | Jenkins, GitHub Actions |
| **Infrastructure** | Terraform, AWS (ECS, RDS, VPC) |
| **Monitoring** | Prometheus, Grafana, ELK Stack |
| **Security** | OWASP ZAP, Trivy, SonarQube |
## 📋 Features
### Application Features
- ✅ RESTful API for user management
- ✅ JWT-based authentication
- ✅ PostgreSQL database integration
- ✅ Comprehensive test coverage (>85%)
- ✅ OpenAPI 3.0 documentation
- ✅ Health checks and metrics endpoints
### DevOps Features
- ✅ Automated CI/CD pipeline
- ✅ Infrastructure as Code with Terraform
- ✅ Multi-environment deployments (dev/staging/prod)
- ✅ Container security scanning
- ✅ Blue-green deployment strategy
- ✅ Automated rollback capabilities
- ✅ Centralized logging and monitoring
## 🏃♂️ Quick Start
### Prerequisites
- Docker and Docker Compose
- AWS CLI configured
- Terraform >= 1.0
- Java 17
- Maven 3.8+
### Local Development
```bash
# Clone the repository
git clone https://github.com/Amid68/java_microservice_infrastructure.git
cd java_microservice_infrastructure
# Start local environment
docker-compose up -d
# Run the application
cd app
./mvnw spring-boot:run
# API will be available at http://localhost:8080
# Swagger UI: http://localhost:8080/swagger-ui.html
```
### Infrastructure Deployment
```bash
# Initialize Terraform
cd infrastructure/terraform/environments/dev
terraform init
# Plan deployment
terraform plan
# Apply infrastructure
terraform apply
```
## 📊 CI/CD Pipeline
The pipeline includes the following stages:
1. **Code Quality** - Static analysis with SonarQube
2. **Testing** - Unit tests, integration tests, and contract tests
3. **Security Scanning** - Dependency and container vulnerability scans
4. **Build & Package** - Maven build and Docker image creation
5. **Deploy to Staging** - Automated deployment to staging environment
6. **Integration Tests** - End-to-end testing in staging
7. **Production Deployment** - Blue-green deployment with manual approval

└─────────────────┘ └──────────────────┘ └─────────────────┘
```
### Key Infrastructure Components
- **VPC** with public and private subnets across multiple AZs
- **ECS Fargate** for container orchestration
- **RDS PostgreSQL** with automated backups
- **Application Load Balancer** with SSL termination
- **CloudWatch** for logging and monitoring
- **IAM roles** following least privilege principle
## 📈 Monitoring & Observability
### Metrics & Monitoring
- Application metrics via Micrometer
- Infrastructure monitoring with CloudWatch
- Custom business metrics dashboard
- Automated alerting for critical issues
### Logging
- Centralized logging with ELK stack
- Structured JSON logging
- Log aggregation across all services
- Log retention policies
## 🔒 Security
### Security Measures Implemented
- Container image vulnerability scanning
- Dependency vulnerability checks
- OWASP security testing
- Secrets management with AWS Secrets Manager
- Network security with security groups
- Encrypted data at rest and in transit
## 🧪 Testing Strategy
### Test Types
- **Unit Tests** - 90%+ coverage requirement
- **Integration Tests** - Database and external service integration
- **Contract Tests** - API contract validation
- **End-to-End Tests** - Full user journey testing
- **Performance Tests** - Load and stress testing
### Test Automation
- Automated test execution in CI pipeline
- Test results reporting and trending
- Quality gates for deployment progression
