Java Spring Boot Microservices: Build Airline Booking System

Descripción

Build a Real Airline Booking Platform with Java Microservices This course teaches you how real systems are built. You’ll create a complete Airline Booking & Reservation Platform using Java Spring Boot Microservices — the same category of architecture used by airline booking systems and travel platforms worldwide. Instead of small CRUD demos, you’ll design and build a distributed backend system with real business workflows, production-grade architecture, event-driven communication, caching strategies, security, and scalable service interactions. By the end of this course, you’ll understand not only how to build microservices — but why modern systems are designed this way. What You’ll Build You’ll build a complete backend Airline Booking Platform featuring: • Flight Search Engine • Seat Availability Management • Fare Pricing System • Booking & Reservation Flow • Payment Integration • JWT Authentication & Authorization • Redis-Based Caching • Kafka Event-Driven Communication • API Gateway & Service Discovery • Notification System • Saga-Based Distributed Transactions • Dockerized Multi-Service Deployment This project simulates a mini Global Distribution System (GDS) similar to systems used by airlines and travel companies. Technologies Covered Backend • Java • Spring Boot • Spring Cloud • Spring Security • Spring Data JPA • Spring Cloud Gateway • Netflix Eureka • OpenFeign • Resilience4j • Apache Kafka • Redis • MySQL Security • JWT Authentication • Role-Based Access Control • Token Revocation using Redis Architecture • Microservices Architecture • Database per Service Pattern • Event-Driven Systems • Saga Pattern • API Gateway Pattern • Distributed Communication DevOps • Docker • Docker Compose • Google Jib • Spring Boot Actuator Integrations • Razorpay • Email Notifications What You’ll Learn Microservices Architecture • Design scalable distributed systems • Split domains into independent services • Handle inter-service communication • Implement API Gateway & Service Discovery Kafka & Event-Driven Systems • Build asynchronous workflows • Publish & consume Kafka events • Implement booking saga flows • Handle failure recovery with compensation events Security & Authentication • Secure APIs using JWT • Implement role-based access control • Manage token blacklisting with Redis Redis Caching • Multi-layer caching strategies • Cache invalidation techniques • Performance optimization Distributed System Design • Fault tolerance • Circuit breakers • Retry mechanisms • Service resilience patterns Real Airline Domain Modeling • Flights & schedules • Fare rules • Seat inventory • Booking lifecycle • Passenger management DevOps & Deployment • Containerize microservices • Docker Compose orchestration • Production-ready deployment workflows Why This Course Is Different Most microservices tutorials build simple ecommerce clones or CRUD demos. This course focuses on: • - Real-world architecture • - Domain-driven thinking • - Event-driven backend systems • - Production-grade patterns • - Large-scale project structure • - Interview-level system design concepts You won’t just learn frameworks. You’ll learn how backend engineers think when building scalable systems. Who This Course Is For Perfect For: • Java developers moving beyond CRUD applications • Spring Boot developers learning microservices • Backend engineers preparing for interviews • Students building strong portfolio projects • Developers interested in Kafka & distributed systems Prerequisites: • Basic Java knowledge • Basic Spring Boot understanding • REST API fundamentals • SQL basics No prior Kafka or microservices experience required. Key Features of the Project Passenger Features • Flight search • Booking flow • Secure payments • E-ticket generation • Email confirmations Airline Admin Features • Flight scheduling • Fare management • Fleet management • Seat inventory management System Features • API Gateway • Kafka Event Streaming • JWT Security • Redis Caching • Circuit Breakers • Dockerized Architecture What Makes This Valuable for Your Career By the end of this course, you’ll have: • A production-grade backend project • Strong system design understanding • Real microservices experience • Kafka architecture knowledge • A standout GitHub portfolio project • Skills used in product-based companies This project demonstrates real backend engineering skills that companies look for in Java developers.
