Stay competitive in today’s software industry by mastering microservices. As microservices architecture becomes the modern standard, this book demystifies the transition from monoliths to microservices with clear guidance and practical examples for easier adoption and implementation.

The book starts with the basics, explaining what microservices are, their benefits, and how they compare to monolithic architectures. From there, you will explore a wide range of topics including service discovery, load balancing, authentication and authorization, resilience, fault tolerance, and much more as well as practical Java examples throughout. Each chapter is meticulously crafted to offer a balance of theory and hands-on application, ensuring you not only understand the concepts but also apply them effectively in real-world scenarios.

By the end of the book, you will be ready to design, implement, and manage scalable and efficient microservices-based systems. Additionally, you will gain a forward-looking perspective on emerging trends and the integration of microservices in AI and IoT.

What You Will Learn

• Compare microservices and monolithic systems, understanding the basics, benefits and key differences
• Understand key principles for decomposing monoliths and designing for failure
• Master synchronous vs. asynchronous communication and when to use each
• Explore containerization, orchestration with Kubernetes, and scaling strategies
• Secure microservices and monitor health and performance in distributed systems

Who This Book Is For

Novice and experienced developers who are new to microservices and want to master the topic to drive successful software projects.
