Online Reservation App

Overview

The Online Reservation App is a microservices-based application designed to efficiently handle reservations. Each service is dedicated to a specific functionality, ensuring scalability, flexibility, and maintainability.

Service List

• Admin Service
  Manages administrative tasks like user roles, permissions, and system settings.

• Auth Service
  Handles authentication and authorization, including login, token generation, and session management.

• Booking Service
  Manages the reservation process, including availability checks, booking creation, updates, and cancellations.

• Compositor Service
  Aggregates data from multiple services to provide a unified view for clients.

• Config Server
  Provides centralized configuration management for all services using Spring Cloud Config.

• Eureka Server
  Implements service discovery for dynamic registration and discovery of microservices.

• Gateway Server
  Acts as a single entry point for clients, providing API routing, load balancing, and security.

• Inventory Service
  Tracks and manages the availability of resources for reservations.

• Message Service
  Facilitates asynchronous communication between services using a messaging queue.

• Profile Service
  Manages user profiles, including personal details, preferences, and reservation history.

Tools Used

• Zookeeper: Distributed coordination for synchronization and fault tolerance.
• Kafka Server: Message queuing for asynchronous and real-time communication between services.
• Zipkin: Distributed tracing for monitoring and debugging microservices.
• Grafana: Advanced data visualization and monitoring.
• Loki: Log aggregation for querying logs seamlessly with Grafana.
• Redis: High-performance in-memory data store for caching and session management.

How to Run

1. Start the Infrastructure

   • Launch Zookeeper, Kafka Server, and Redis.
   • Set up monitoring tools (Zipkin, Grafana, Loki).

2. Run Services

   • Start configserverboot3 to load configurations.
   • Start eurekaserverboot3 for service discovery.
   • Launch the remaining services in the required order.

3. Access the Application

   • Use the Gateway Server (gatewayserverboot3) as the entry point.
   • API endpoints and documentation are available through the gateway.

Monitoring and Debugging

• Use Grafana for performance monitoring and dashboards.
• Query logs through Loki for troubleshooting.
• Trace requests across services with Zipkin.
