Flight Reservation System

Overview

The flight reservation system is a web platform that provides the facility to search and book tickets online. It helps to manage the ticket booking records as well as the booking records and the details of the customers going to travel.

This project is following microservice-architecture and build with the help of NodeJs. Each request is first sent to the gateway which forwards it based on the request country, it then reaches the country load balancer which redirects to the nearest registered microservice.
