Welcome to the Shah's Bakery Microservice Platform repository! This platform provides an integrated and scalable system specifically designed for managing bakery operations driven by microservices.

Modern bakeries face numerous challenges like:

• Managing perishable inventory
• Coordinating orders
• Engaging customers with timely notifications
• Ensuring smooth payment and delivery workflows

Our modular microservice architecture offers a flexible, robust solution to meet these needs efficiently. Each microservice is focused on a key business domain, enabling independent development, deployment, and scaling for maximum agility.

The platform follows microservice architectural principles, with services communicating over REST APIs and built using the Spring Boot and Spring Cloud stack.

• Scalability: Services scale independently based on load.
• Resilience: Failure isolation with robust error handling.
• Modularity: Domain-driven design for maintainability.
• Rapid Deployment: Faster development and CI/CD.
• Technology Diversity: Best tech choices per service.

• Spring Boot – Rapid REST API development
• Spring Cloud Netflix Eureka – Service registry and discovery
• Spring Cloud OpenFeign – Declarative REST clients
• Spring Security (OAuth2 / JWT) – Authentication and authorization
• Spring Data JPA + PostgreSQL – Resilient data persistence
• Redis – Caching and session state
• Quartz Scheduler – Task and campaign scheduling
• AWS SNS – Push notification delivery
• Twilio – SMS messaging
• Thymeleaf – Email template generation
• Spring Retry – Resilient communication
• Spring Boot Actuator – Metrics and health checks
• OpenAPI / Swagger – API documentation
• JUnit 5 + Testcontainers – Testing infrastructure
• Docker + Docker Compose – Containerization and orchestration

1. Clone this repository.
2. Configure each microservice's application.yml for database, messaging, and third-party credentials.
3. Build and run services independently or via Docker Compose.
4. Use the API Gateway as the central entry point.
5. Explore interactive API docs via Swagger UI.

We are currently working on integrating Apache Kafka into Shah's Bakery Microservice Platform to enhance real-time communication and event-driven architecture across services.

Apache Kafka is a distributed event streaming platform that enables high-throughput, fault-tolerant, and scalable messaging between microservices.

• Event-Driven Architecture: Services will publish and subscribe to events (e.g., order placed, payment confirmed, product restocked) for better decoupling and responsiveness.
• Real-Time Updates: Enables instant updates across services like inventory, notifications, and order tracking.
• Scalability: Kafka handles high volumes of data efficiently, supporting bakery growth and peak traffic.
• Resilience: Durable message storage and replay capabilities improve fault tolerance and recovery.
• Audit and Traceability: Kafka topics can serve as a reliable audit trail for business events.

• Define Kafka topics and event schemas.
• Configure Kafka brokers and producers/consumers in each service.
• Implement retry and dead-letter queues for failed message handling.
• Monitor Kafka metrics via Spring Boot Actuator and Prometheus.

Stay tuned as we roll out Kafka-powered features to make Shah's Bakery more responsive and intelligent!
