Booking System Microservices

Overview

This repository contains a microservices-based booking system with two primary services: Hotels and Booking. The system is built using .NET Core, Docker, Kubernetes, RabbitMQ, and Mediatr. It follows Domain-Driven Design (DDD), Command Query Responsibility Segregation (CQRS), and Event Sourcing patterns.

Architecture

The architecture of this booking system is designed to be scalable, maintainable, and resilient. Here's a brief overview of the components:

Services

Hotels Service

• Manages hotel information such as availability, pricing, and details.
• Exposes APIs for CRUD operations on hotel data.

Booking Service

• Manages bookings and reservations.
• Handles the entire booking lifecycle from creation to cancellation.

Technologies

• .NET Core: The primary framework for building the microservices.
• Docker: Used for containerizing the microservices for easy deployment and scaling.
• Kubernetes: Manages container orchestration, ensuring that the microservices are running as expected in a cluster environment.
• RabbitMQ: Acts as the message broker to facilitate communication between microservices.
• Mediatr: Implements the mediator pattern for handling requests and notifications within the services.
• DDD (Domain-Driven Design): Provides a structured approach to designing the system by modeling the business domain.
• CQRS (Command Query Responsibility Segregation): Segregates read and write operations to optimize performance and scalability.
• Event Sourcing: Ensures that all changes to the application state are stored as a sequence of events, providing a reliable audit log and supporting complex business workflows.
