This repository contains a microservice application built with Spring Boot and Spring Cloud, demonstrating various distributed patterns such as:
- Configuration Server for centralized configuration management
- Discovery Server (Eureka) for service registration and discovery
- API Gateway for routing requests and aggregating responses
- Asynchronous Communication using Kafka for event-driven architecture
- Synchronous Communication with OpenFeign and RestTemplate for RESTful service calls
- Deployment with Kubernetes resources using the Jib Maven Plugin
The application is structured as a monorepo containing several microservices, each responsible for distinct functionalities within the e-commerce platform. The architecture follows best practices for microservice design and communication.
- Configuration Server: Manages application configuration settings.
- Discovery Service: Registers and discovers services using Eureka.
- API Gateway: Serves as the entry point for client requests, routing them to appropriate microservices.
- Order Service: Handles order processing and management.
- Payment Service: Manages payment processing and transactions.
- Customer Service: Manages customer data and interactions.
- Product Service: Manages product information and inventory.
- Notification Service: Sends notifications to users (email, SMS, etc.).
- Zookeeper: Optional service for distributed coordination (if used).
- Spring Boot: For building microservices
- Spring Cloud: For cloud-native features and service orchestration
- Kafka: For message brokering and asynchronous communication
- Eureka: For service discovery
- OpenFeign: For declarative REST client
- RestTemplate: For synchronous RESTful communication
- Kubernetes: For container orchestration and deployment
- Jib: For building Docker images directly from Maven
- Helm: For managing Kubernetes applications
A Helm chart is included in this project to facilitate the deployment of the microservices to a Kubernetes cluster. The chart can be found in the k8s/ directory.
