Implementing Domain-Driven Design
Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.
Building on Eric Evans’ seminal book, Domain-Driven Design, Vaughn presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples—all applicable to C# developers—and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.
Vaughn Vernon, the author, takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.
- Getting started the right way with DDD, so you can rapidly gain value from it
- Using DDD within diverse architectures, including Hexagonal, SOA, REST, CQRS, Event-Driven, and Fabric/Grid-Based
- Appropriately designing and applying Entities–and learning when to use Value Objects instead
- Mastering DDD’s powerful new Domain Events technique
- Designing Repositories for ORM, NoSQL, and other databases
What Others Are Saying
“With Implementing Domain-Driven Design , Vaughn has made an important contribution not only to the literature of the Domain-Driven Design community, but also to the literature of the broader enterprise application architecture field. In key chapters on Architecture and Repositories, for example, Vaughn shows how DDD fits with the expanding array of architecture styles and persistence technologies for enterprise applications—including SOA and REST, NoSQL and data grids—that has emerged in the decade since Eric Evans’ seminal book was first published. And, fittingly, Vaughn illuminates the blocking and tackling of DDD—the implementation of entities, value objects, aggregates, services, events, factories, and repositories—with plentiful examples and valuable insights drawn from decades of practical experience. In a word, I would describe this book as thorough. For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.”

“Domain-Driven Design is a powerful set of thinking tools that can have a profound impact on how effective a team can be at building software-intensive systems. The thing is that many developers got lost at times when applying these thinking tools and really needed more concrete guidance. In this book, Vaughn provides the missing links between theory and practice. In addition to shedding light on many of the misunderstood elements of DDD, Vaughn also connects new concepts like Command/Query Responsibility Segregation and Event Sourcing that many advanced DDD practitioners have used with great success. This book is a must-read for anybody looking to put DDD into practice.”
—Udi Dahan, Founder of NServiceBus
“For years, developers struggling to practice Domain-Driven Design have been wishing for more practical help in actually implementing DDD. Vaughn did an excellent job in closing the gap between theory and practice with a complete implementation reference. He paints a vivid picture of what it is like to do DDD in a contemporary project, and provides plenty of practical advice on how to approach and solve typical challenges occurring in a project life cycle.”
— Alberto Brandolini, DDD Instructor, Certified by Eric Evans and Domain Language, Inc.
“Implementing Domain-Driven Design does a remarkable thing: it takes a sophisticated and substantial topic area in DDD and presents it clearly, with nuance, fun and finesse. This book is written in an engaging and friendly style, like a trusted advisor giving you expert counsel on how to accomplish what is most important. By the time you finish the book you will be able to begin applying all the important concepts of DDD, and then some. As I read, I found myself highlighting many sections . . . I will be referring back to it, and recommending it, often.”
— Paul Rayner, Principal Consultant & Owner, Virtual Genius, LLC., DDD Instructor, Certified by Eric Evans and Domain Language, Inc., DDD Denver Founder and Co-leader
“One important part of the DDD classes I teach is discussing how to put all the ideas and pieces together into a full blown working implementation. With this book, the DDD community now has a comprehensive reference that addresses this in detail. Implementing Domain-Driven Design deals with all aspects of building a system using DDD, from getting the small details right to keeping track of the big picture. This is a great reference and an excellent companion to Eric Evans seminal DDD book.”
— Patrik Fredriksson, DDD Instructor, Certified by Eric Evans and Domain Language, Inc.
“If you care about software craftsmanship—and you should—then Domain-Driven Design is a crucial skill set to master and Implementing Domain-Driven Design is the fast path to success. IDDD offers a highly readable yet rigorous discussion of DDD’s strategic and tactical patterns that enables developers to move immediately from understanding to action. Tomorrow’s business software will benefit from the clear guidance provided by this book.”
—Dave Muirhead, Principal Consultant, Blue River Systems Group
“There’s theory and practice around DDD that every developer needs to know, and this is the missing piece of the puzzle that puts it all together. Highly recommended!”
—Rickard Öberg, Java Champion and Developer at Neo Technology
“In IDDD, Vaughn takes a top-down approach to DDD, bringing strategic patterns such as bounded context and context maps to the fore, with the building block patterns of entities, values and services tackled later. His book uses a case study throughout, and to get the most out of it you’ll need to spend time grokking that case study. But if you do you’ll be able to see the value of applying DDD to a complex domain; the frequent sidenotes, diagrams, tables, and code all help illustrate the main points. So if you want to build a solid DDD system employing the architectural styles most commonly in use today, Vaughn’s book comes recommended.”
—Dan Haywood, author of Domain-Driven Design with Naked Objects
“This book employs a top-down approach to understanding DDD in a way that fluently connects strategic patterns to lower level tactical constraints. Theory is coupled with guided approaches to implementation within modern architectural styles. Throughout the book, Vaughn highlights the importance and value of focusing on the business domain all while balancing technical considerations. As a result, the role of DDD, as well as what it does and perhaps more importantly doesn’t imply, become ostensibly clear. Many a time, my team and I would be at odds with the friction encountered in applying DDD. With Implementing Domain-Driven Design as our luminous guide we were able to overcome those challenges and translate our efforts into immediate business value.”

Domain-Driven Design Distilled
Read Domain-Driven Design Distilled. Domain-Driven Design (DDD) software modeling delivers powerful results in practice, not just in theory, which is why developers worldwide are rapidly moving to adopt it. Now, for the first time, there’s an accessible guide to the basics of DDD: What it is, what problems it solves, how it works, and how to quickly gain value from it.
Concise, readable, and actionable, Domain-Driven Design Distilled never buries you in detail–it focuses on what you need to know to get results. Vaughn Vernon, author of the best-selling Implementing Domain-Driven Design, draws on his twenty years of experience applying DDD principles to real-world situations. He is uniquely well-qualified to demystify its complexities, illuminate its subtleties, and help you solve the problems you might encounter.
Vernon guides you through each core DDD technique for building better software. You’ll learn how to segregate domain models using the powerful Bounded Contexts pattern, to develop a Ubiquitous Language within an explicitly bounded context, and to help domain experts and developers work together to create that language. Vernon shows how to use Subdomains to handle legacy systems and to integrate multiple Bounded Contexts to define both team relationships and technical mechanisms.
Domain-Driven Design Distilled brings DDD to life. Whether you’re a developer, architect, analyst, consultant, or customer, Vernon helps you truly understand it so you can benefit from its remarkable power.

Reactive Messaging Patterns with the Actor Model
Reactive Messaging Patterns with the Actor Model enables enterprise developers to solve complex application and integration problems that were nearly impossible to address before. Developers can build multi-core, multi-threaded, highly-scalable, high performance, low-latency systems, and write composable software that is event-driven, scalable under load, responsive, and highly resilient. Developers are increasingly recognizing the potential of these technologies, and companies including Lightbend, VMware, and SpringSource have recently released new tools for using them. Now, there’s a start-to-finish guide to using reactive programming and the Actor model with Scala and Akka: Reactive Messaging Patterns with the Actor Model.
The book begins with a concise, usable review of programming with the Actor model and the Scala language and the Akka toolkit. Next, Vaughn presents a guide to achieving high performance using the threading model supplied with actor systems. Following this is an easy-to-adapt cookbook of solutions for message-based applications and integration. The detailed solutions address messaging systems, channels, construction, routing, transportation, endpoints, and system management. Each follows the proven format introduced by Gregor Hohpe and Bobby Woolf in their popular Enterprise Integration Patterns, while offering advanced solutions based on Scala and Akka. Using this guide’s insights and examples, you can take Scala programming to the next level, applying Scala with the Akka toolkit to achieve maximum organizational value.
