“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.” –Randy Stafford, Architect At-Large, Oracle Coherence Product Development “This book is a must-read for anybody looking to put DDD into practice.” –Udi Dahan, Founder of NServiceBus 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, the author 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. 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. Coverage includes 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

Make Architecture Choices That Free You to Maximize Value and Innovation "The heart of this book is a large set of thinking tools that will help you design a new architecture . . . and the organization needed to support that architecture. The book then offers ways to gradually move from your existing architecture toward the new one. . . . There is no formula for success other than the one offered [here]: highly skilled people, deep thinking, and constant experimentation." --From the Foreword by Mary Poppendieck, coauthor, Lean Software Development Strategic Microservices and Monoliths helps business decision-makers and technical team members collaborate to clearly understand their strategic problems and identify their optimal architectural approaches, whether these prove to be distributed microservices, well-modularized monoliths, or coarser-grade services partway between the two. Leading software architecture experts Vaughn Vernon and Tomasz Jaskua show how to make balanced architecture decisions based on need and purpose, not hype so you can promote value and innovation, deliver more evolvable systems, and avoid costly mistakes. Using realistic examples, they show how to construct well-designed monoliths that are maintainable and extensible, and how to gradually tease out even the most tangled legacy systems into truly effective microservices. Link software architecture planning to business innovation and digital transformation Overcome communication problems to promote experimentation and discovery-based innovation Master practices that support your value-generating goals and help you invest more strategically Compare architectural styles that can lead to versatile, adaptable applications and services Recognize when monoliths are your best option and how best to architect, design, and implement them Learn when to move monoliths to microservices and how to do it, whether they're modularized or a "Big Ball of Mud"

要件最適アーキテクチャ戦略

Most recent microservices books fully buy into the hype, starting from the premise that microservices are nearly always the best approach to developing enterprise systems. But that isn't always a safe assumption: in fact, in some cases, it can be disastrous, leading to architectures that serve nobody well. Strategic Microservices and Monoliths helps business decision-makers and technical team members collaborate to clearly understand their strategic problems, and identify their optimal architectural approaches, whether those turns out to be distributed microservices, well-modularized monoliths, or coarser-grade services partway between the two. Writing for executives and IT professionals alike, leading software architecture expert Vaughn Vernon and Tomasz Jaskula guide you through making balanced architecture compositional decisions based on need and purpose rather than popular opinion, so you can maximize business value and deliver systems that evolve more easily. Throughout, the authors provide realistic application examples, showing how to construct well-designed monoliths that are maintainable and extensible, and how to decompose massively tangled legacy systems into truly effective microservices.

Domain-Driven Design (DDD) richtet den Fokus in der Softwareentwicklung auf das Wesentliche: die Domäne. Die Domäne wird als Modell in die Software übertragen. Damit entwickeln Sie Software in hoher Qualität, die lange hält, den Anwender zufriedenstellt und die Basis für Microservices bildet. Dieses Buch bietet einen kompakten Einstieg in DDD. Die wesentlichen Konzepte, wie die Entwicklung einer Ubiquitous Language, das Aufteilen der Domäne in Bounded Contexts und die Konstruktion innerhalb von Bounded Contexts, werden vermittelt. Außerdem wird die Anbindung von Legacy-Systemen behandelt. Die Themen im Einzelnen: - Strategisches Design mit Bounded Contexts und der Ubiquitous Language - Strategisches Design mit Subdomains - Strategisches Design mit Context Mapping - Taktisches Design mit Aggregates - Taktisches Design mit Domain Events Auch auf Techniken zur Beschleunigung von Design und das Management von Projekten wird eingegangen. Insbesondere wird erläutert, wie Event Storming, DDD in einem agilen Projekt und die Modellierung mit Timebox funktionieren. Der Leser findet in diesem Buch viele konkrete Handlungsvorschläge für die Praxis und wird so befähigt, die Zusammenarbeit von Entwicklern und Domain Experts sowie zwischen Teams zu fördern. Als Extra befindet sich ein Glossar mit den wichtigsten DDD-Begriffen auf den Umschlaginnenseiten.

Domain-Driven Design kompakt

USE THE ACTOR MODEL TO BUILD SIMPLER SYSTEMS WITH BETTER PERFORMANCE AND SCALABILITY Enterprise software development has been much more difficult and failure-prone than it needs to be. Now, veteran software engineer and author Vaughn Vernon offers an easier and more rewarding method to succeeding with Actor model. Reactive Messaging Patterns with the Actor Model shows how the reactive enterprise approach, Actor model, Scala, and Akka can help you overcome previous limits of performance and scalability, and skillfully address even the most challenging non-functional requirements. Reflecting his own cutting-edge work, Vernon shows architects and developers how to translate the longtime promises of Actor model into practical reality. First, he introduces the tenets of reactive software, and shows how the message-driven Actor model addresses all of them–making it possible to build systems that are more responsive, resilient, and elastic. Next, he presents a practical Scala bootstrap tutorial, a thorough introduction to Akka and Akka Cluster, and a full chapter on maximizing performance and scalability with Scala and Akka. Building on this foundation, you’ll learn to apply enterprise application and integration patterns to establish message channels and endpoints; efficiently construct, route, and transform messages; and build robust systems that are simpler and far more successful. Coverage Includes How reactive architecture replaces complexity with simplicity throughout the core, middle, and edges The characteristics of actors and actor systems, and how Akka makes them more powerful Building systems that perform at scale on one or many computing nodes Establishing channel mechanisms, and choosing appropriate channels for each application and integration challenge Constructing messages to clearly convey a sender’s intent in communicating with a receiver Implementing a Process Manager for your Domain-Driven Designs Decoupling a message’s source and destination, and integrating appropriate business logic into its router Understanding the transformations a message may experience in applications and integrations Implementing persistent actors using Event Sourcing and reactive views using CQRS Find unique online training on Domain-Driven Design, Scala, Akka, and other software craftsmanship topics using the for{comprehension} website at forcomprehension.com.
