Description
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 onlyhow to build microservices - butwhy modern systems are designed this way.
What You'll Build

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

Java developers who want to move beyond basic CRUD applications

Spring Boot developers interested in learning real microservices architecture

Developers who want hands-on experience with Kafka and distributed systems

Full-stack developers who want deeper backend architecture knowledge

Developers aiming to understand system design through real implementation instead of theory

Anyone wanting practical experience with Docker, Redis, JWT, API Gateway, and Spring Cloud

Developers who want to learn how real airline booking systems work
