As a mentor and practitioner with 12+ years in product-based organizations, I am proud to present this book on Microservice Design Patterns—crafted specifically for building real-world distributed systems.
 
This book is not theoretical. It is scripted from real-time industry experience, keeping system design interviews for Java developers and deep architectural learning at its core. Over the years, I have interviewed 800+ engineers and trained 20,000+ Java developers, and one pattern consistently stood out:
Strong DSA and Java skills are common.
Strong system design thinking is not.
 
Most engineers struggle when asked to design scalable, resilient, and production-ready systems. This book is my effort to bridge that gap—the gap between writing good code and building systems that survive, scale, and remain stable in production.
 
For senior engineers, system design is not optional.
Better Java or DSA alone is never sufficient to sustain a system.
Architecture and design decisions define system longevity.
This book covers 100+ widely used microservice and distributed system design patterns, each explained with:
 
Real-time industry use cases
Practical, job-oriented code examples
Patterns frequently asked in interviews and applied in day-to-day engineering work
 
Every chapter is grounded in actual problems engineers face in production, following industry-grade best practices in system design and architecture.
If you want to move from being a good developer to a reliable system designer, this book is written for you.
 
What makes this book different?
100+ most-used design patterns—the same ones asked in system design interviews
Real-time use cases taken directly from day-to-day engineering work
Practical Java-based code examples, not pseudo-theory
Industry-grade architecture thinking, used by senior engineers in production
Patterns that help you design systems, not just talk about them
 
Who Should Read This Book?
Any engineer who wants to master system design and architecture, beyond just writing code.
Developers preparing for job changes, especially for system design interview rounds in product-based companies.
Working professionals who want to innovate, rethink how systems work, and design scalable, resilient architectures.
Engineers across all experience levels (0–20+ years)—from fresh graduates to senior and staff engineers.
Developers seeking real-time industry exposure, practical thinking, and patterns used in day-to-day production systems.

About the Author
Amitesh Kumar Ray is a seasoned software engineering leader with 12+ years of hands-on experience in building and scaling systems for product-based MNCs in India and abroad. He currently works as a Lead Software Development Engineer (Lead SDE) at M2P, where he designs and delivers large-scale, production-grade distributed systems.
 
An accomplished author, Amitesh has written nearly 20 technical books spanning Java, Spring Boot, Microservices, System Design, Architecture, and AI tooling. His writing reflects what truly matters in the industry—clarity of thought, architectural depth, and real-world applicability.
He holds a certification in System Design and Architecture from the University of Alberta and is currently pursuing an Advanced Certification in AI & Machine Learning from IIT Madras, reinforcing his commitment to continuous learning and modern engineering practices.
 
Amitesh has built multiple products from the ground up, navigated complex production failures, and solved real scalability, reliability, and performance challenges—experiences that directly shape the content of this book.
 
Beyond engineering, he has interviewed 800+ Java developers and mentored and trained over 20,000 engineers. Through these interactions, he identified a recurring gap: while many developers write good code, very few are confident in system design and architectural thinking. This book is his effort to bridge that gap, guiding developers to think like architects and build systems that scale, survive, and evolve in the real world.
 
His mission is simple: help engineers move from writing applications to designing systems.
