After reading this book, you will understand the benefits of using immutable objects in your distributed systems. You'll learn a set of rules for identifying and exchanging immutable objects, and you'll see a collection of useful theorems that ensure that the distributed systems you build have eventual consistency. Using patterns, you will find where truth converges, see how change occurs associatively rather than sequentially, and come to a comfortable understanding that there is no single source of truth. The practical examples provided clearly show how to create software using the described patterns, methods and tools. By the end of reading, you will have the language and resources necessary to confidently analyze and build distributed systems.

The book is intended for software architects and experienced developers. It contains examples in SQL and languages such as JavaScript and C#. Experience with distributed computing, data modeling, or business analysis is helpful.
