MicroServices-Project

#Application Overview We will be building a simple e-commerce application where customers can order products. Our application contains the following services: Product Service Order Service Inventory Service Notification Service

To focus on the principles of Spring Cloud and Microservices, we developed services with essential functionality rather than creating fully-featured e-commerce services.

Features & Implementations

1️⃣ RESTful API Development

• Developed RESTful services using Spring Boot 3, following best practices.

2️⃣ Inter-Service Communication

• Implemented synchronous communication using Spring Cloud OpenFeign.

3️⃣ Service Discovery

• Integrated Spring Cloud Netflix Eureka for dynamic service registration and discovery.

4️⃣ API Gateway

• Configured Spring Cloud Gateway for centralized request routing and security.

5️⃣ Security & Authentication

• Implemented Keycloak for authentication, authorization, and identity management.

6️⃣ Resilience & Fault Tolerance

• Used Resilience4J for circuit breaking, ensuring high availability.

7️⃣ Event-Driven Architecture

• Leveraged Kafka for asynchronous communication and event processing.

8️⃣ Observability & Monitoring

• Distributed Tracing using OpenTelemetry & Grafana Tempo.
• Log Aggregation with Grafana Loki.
• Metrics Collection & Visualization via Prometheus & Grafana dashboards.

9️⃣ Containerization & Deployment

• Docker for containerizing services.
• Docker Compose for managing multi-container applications.
• Kubernetes migration for scalability, orchestration, and high availability.
