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 Monoliths and Microservices helps business decision-makers and technical team members collaborate to clearly understand their strategic problems, and identify their optimal architectural approaches, whether those turn out to be distributed microservices, well-modularized monoliths, or coarse-grained 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.
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 Jaskula 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
