Strategic Microservices and Monoliths

Make Software Architecture Choices That Maximize Value and Innovation
＂[Vernon and Jaskula] provide insights, tools, proven best practices, and architecture styles both from the business and engineering viewpoint. . . . This book deserves to become a must-read for practicing software engineers, executives as well as senior managers.＂
--Michael Stal, Certified Senior Software Architect, Siemens Technology
Strategic Monoliths and Microservices helps business decision-makers and technical team members clearly understand their strategic problems through collaboration and identify optimal architectural approaches, whether the approach is distributed microservices, well-modularized monoliths, or coarser-grained services partway between the two.

Leading software architecture experts Vaughn Vernon and Tomasz Jaskula show how to make balanced architectural decisions based on need and purpose, rather than 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 redesign and reimplement 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＂

Vaughn Vernon (Carefree, AZ), a software developer with 30+ years of experience in a broad range of business domains, is a world-renowned expert in Domain-Driven Design (DDD) and champion of simplicity and Reactive systems. As a consultant and teacher of DDD and Reactive software development, he has helped thousands of developers transform brittle, stagnating, technology-driven systems into innovative, business-driven systems that deliver far more value. The visionary and Chief Architect behind the VLINGO/PLATFORM, he is author of Implementing Domain-Driven Design, Domain-Driven Design Distilled, and Reactive Messaging Patterns with the Actor Model, all published by Addison-Wesley.

Tomasz Jaskula (Paris, France Area) has 20 years of professional experience as a developer, software architect, team leader, trainer, and technical conference speaker. An IDDD Workshop trainer in both French and Polish, he founded Paris Domain-Driven Design and F# user groups. Jaskula’s company, Luteceo (luteceo.fr), spreads good software and architecture practices based on Domain-Driven Design and software craftsmanship. He previously worked for many companies in e-commerce, industry, insurance, and finance, gaining deep experience for creating software that delivers clear business value and competitive advantage.
