Modern Microservices Architecture Showcase

This project demonstrates core microservices concepts using modern Spring ecosystem features, reactive programming, messaging, and monitoring tools. It includes multiple example services to illustrate different architectures and patterns.

---

Technologies Used

• Spring Boot & Spring WebFlux (Reactive)
• Spring Cloud Gateway & API Gateway
• Service Registry (Eureka)
• JWT Authentication
• Reactive Security & Authorization
• Kafka Messaging (Event-driven architecture)
• Centralized Configuration
• Distributed Logging
• Docker & Docker Compose
• Monitoring: Prometheus & Grafana
• Distributed Tracing: Tempo

---

Project Structure

1. Authentication & Reactive Service

   • Uses Spring WebFlux and JWT for secure reactive endpoints
   • Demonstrates non-blocking, reactive microservices patterns

2. Kafka & Reactive Web Services

   • Event-driven architecture using Kafka for messaging between services
   • Reactive REST endpoints handling high-throughput, asynchronous processing

3. Monitoring & Sample Services

   • Monitoring service integrated with Prometheus & Grafana
   • Sample microservices demonstrating logging, tracing, and service registry

How to Run

Make sure Docker and Docker Compose are installed, then run each service using:

docker-compose up --build
