✈️ Build a Real Airline Booking System | Spring Boot Microservices

Most Java developers stop at CRUD applications. Very few ever build a real distributed system . In this course, you won’t just learn microservices — you’ll build a full-scale Airline Global Distribution System (GDS) from scratch. This is the same category of system used by platforms like Amadeus and Sabre — but here, you’ll understand every layer of it. 🧠 What You’ll Build You’ll build a complete Airline Booking Platform , including: Flight search with real-world filters Seat selection with cabin-level maps Fare pricing & baggage rules Ancillary services (meals, insurance) Secure payment integration Booking confirmation with notifications All powered by: 11 backend microservices Event-driven communication using Kafka A unified API Gateway A modern React frontend 👉 Think of it as your own mini-Amadeus — built by you. 🏗️ Project Overview A Global Distribution System (GDS) is the backbone of airline booking. Every time someone books a flight online, a system like this is working behind the scenes: Managing inventory Calculating fares Handling seat availability Processing bookings What makes this project special: ✅ Real-world domain modeling (airlines, fares, seats, baggage) ✅ Event-driven booking flow (Kafka-based saga) ✅ Database per service (no shared DB anti-pattern) ✅ Production-grade architecture decisions ⚙️ Tech Stack 🖥️ Backend Spring Boot + Spring Cloud Netflix Eureka (Service Discovery) Spring Cloud Gateway (API Gateway) OpenFeign + Resilience4j (Circuit Breaker) A
