Strategic Monoliths and Microservices: Driving Innovation Using Purposeful Archi

Description: Strategic Monoliths and Microservices by Vaughn Vernon, Tomasz Jaskula Make Software Architecture Choices That Maximize Value and Innovation "[Vernon and Jaskua] 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 Jaskua 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 transformationOvercome communication problems to promote experimentation and discovery-based innovationMaster practices that support your value-generating goals and help you invest more strategicallyCompare architectural styles that can lead to versatile, adaptable applications and servicesRecognize when monoliths are your best option and how best to architect, design, and implement themLearn when to move monoliths to microservices and how to do it, whether theyre modularized or a "Big Ball of Mud" Register your book for convenient access to downloads, updates, and/or corrections as they become available.

Strategic Monoliths and Microservices provides a comprehensive approach to blending the needs of business and technology in an approachable way. It also dispels many of todays myths while offering practical guidance that any team or organization can apply immediately and with confidence." --James Higginbotham, Executive API Consultant, Founder of LaunchAny, and author of Principles of Web API Design "Digital Transformation cannot succeed as a grass roots effort. Vaughn and Tomasz offer C-level execs a roadmap to software excellence that includes establishing the culture necessary to foster and sustain software innovation. Written with real-world understanding, Vaughn and Tomasz help the reader to appreciate that moving software development from a cost center to a profit center involves tradeoffs that need not sacrifice innovation. A must-read for decision makers." --Tom Stockton, Principal Architect, MAXIMUS "In this book, Vaughn Vernon and Tomasz Jaskua use their extensive experience with DDD to present a comprehensive guide to using the many different aspects of DDD for modern systems development and modernization. It will be a valuable guide for many technical leaders who need to understand how to use DDD to its full potential." --Eoin Woods, software architect and author "There are common misconceptions and roots of failure around software engineering. One notable example is neglecting the rugged trek towards digital transformation. Such an endeavor comprises breakthrough innovations, failure culture, emphasis on the role of software architecture, as well as on the importance of efficient and effective inter-human communication. Fortunately, the authors offer the necessary help for mastering all hurdles and challenges. What I like most about this book is the holistic view it provides to all stakeholders involved in digital transformation and innovation. Vaughn Vernon and Tomasz Jaskua introduce a clear path to successful innovation projects. They provide insights, tools, proven best practices, and architecture styles both from the business and engineering viewpoint. Their book sheds light on the implications of digital transformation and how to deal with them successfully. This book deserves to become a must-read for practicing software engineers, executives, as well as senior managers. It will always serve me as a precious source of guidance and as a navigator whenever I am entering uncharted territories." --Michael Stal, Certified Senior Software Architect, Siemens Technology "Digital transformation is a much used but little understood concept. This book provides valuable insight into this topic and how to leverage your existing assets on the journey. Modern technical and social techniques are combined in the context of a single case study. Compelling reading for both business and technology practitioners." --Murat Erder, co-author of Continuous Architecture in Practice (2021) and Continuous Architecture (2015) "Packed with insightful recommendations for every executive leader seeking clarity on the distinction between when to strategically apply a monolith vs. microservice architectural approach for success. Highly encourage every CEO, CIO, CTO, and (S)VP of Software Development to start here with immersing themselves in Vaughn and Tomaszs succinct distillation of the advantages, disadvantages, and allowance for a hybrid combination, and then go become a visionary thought leader in their respective business domain." --Scott P. Murphy, Principal Architect, Maximus, Inc. "A must-read for Enterprise leaders and architects who are planning for or executing a digital transformation! The book is a true guide for ensuring your enterprise software innovation program is successful." --Chris Verlaine, DHL Express Global Aviation IT DevOps Director, Head of DHL Express Global Aviation IT Software Modernization Program " Strategic Monoliths and Microservices is a great resource to connect business value to an evolvable enterprise architecture. I am impressed with how the authors use their deep understanding and experience to guide informed decisions on the modularization journey. Along the way every valuable tool and concept is explained and properly brought into context. Definitely a must-read for IT decision makers and architects. For me this book will be an inspiring reference and a constant reminder to seek the purpose in architecture. The Microservices discussion has reached a completely new maturity level." --Christian Deger, Head of Architecture and Platform at RIO | The Logistics Flow, organizer of over 60 Microservices Meetups "The choice of microservices or monoliths architecture goes far beyond technology. The culture, organization, and communication that exist within a company are all important factors that a CTO must consider carefully in order to successfully build digital systems. The authors explain this extremely well from various perspectives and based on very interesting examples." --Olivier Ulmer, CTO, Groupe La Française "Building a technology engine to move quickly, experiment, and learn is a competitive advantage in todays digital world. Will de-jour architecture help with this endeavor? This amazing book by Vaughn and Tomasz fills a void in the market and re-focuses on the core objectives of software architecture: move fast, experiment, focus on the outcomes that bring value. A reader will come away better suited to decide whether microservices architecture and all the complexity with it is right for them." --Christian Posta, Global Field CTO, Solo.io Long Description 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 isnt 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.
