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 MBA and IT students alike, leading software architecture expert Vaughn Vernon and Tomasz Jasku+éa 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.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
