Microservices Application

A microservices-based backend application built using Java and Spring Boot. The project demonstrates how multiple independent services communicate with each other using Spring Cloud components.

🚀 Services

1. API Gateway

Acts as the single entry point for client requests and routes requests to the appropriate microservice.

2. Service Registry

Provides service discovery so that microservices can locate and communicate with each other.

3. Config Server

Centralizes configuration for the different microservices.

4. User Service

Handles user-related operations.

5. Hotel Service

Handles hotel-related operations and hotel information.

6. Rating Service

Handles ratings and review-related operations.
