Learn with 44 patterns
Architecture problem solving and know-how!

Let's understand and apply it properly
Successfully building applications based on a microservices architecture requires not only understanding the concepts of the new architecture, but also a shift in mindset.
Breaking down a monolith into multiple services with fragmented knowledge does not improve performance.
This book provides a proper guide to what microservices are, what their pros and cons are, and when and where to use them.

Learn with 44 patterns based on experience.
The author, a microservices pioneer and Java champion, explains how to solve various difficult problems such as service decomposition, transaction management, query, and inter-service communication using 44 patterns collected and classified.
In addition to the author's decades of experience building distributed systems, it also covers the patterns needed to write services in practice and how to combine patterns to make systems scale and run.
In particular, it goes beyond simply listing patterns and is full of experience-driven advice useful for designing, implementing, testing, and deploying microservices applications.

Let's test it with a Java-based example
We provide a Spring-based 'online food delivery service' example that allows you to experience microservices.
This service includes several services such as 'Consumer Creation, Restaurant Creation, Order Creation and Inquiry, and Order History Inquiry', and you can understand the microservice architecture by running the code directly.
