The award‎-winning and highly influential Software Architecture in Practice‎,‎ Third Edition‎,‎ has been substantially revised to reflect the latest developments in the field‎.‎ In a real‎-world setting‎,‎ the book once again introduces the concepts and best practices of software architecture‎-how a software system is structured and how that system‎'‎s elements are meant to interact‎.‎ Distinct from the details of implementation‎,‎ algorithm‎,‎ and data representation‎,‎ an architecture holds the key to achieving system quality‎,‎ is a reusable asset that can be applied to subsequent systems‎,‎ and is crucial to a software organization‎'‎s business strategy‎.‎The authors have structured this edition around the concept of architecture influence cycles‎.‎ Each cycle shows how architecture influences‎,‎ and is influenced by‎,‎ a particular context in which architecture plays a critical role‎.‎ Contexts include technical environment‎,‎ the life cycle of a project‎,‎ an organization‎'‎s business profile‎,‎ and the architect‎'‎s professional practices‎.‎ The authors also have greatly expanded their treatment of quality attributes‎,‎ which remain central to their architecture philosophy‎-with an entire chapter devoted to each attribute‎-and broadened their treatment of architectural patterns‎.‎If you design‎,‎ develop‎,‎ or manage large software systems ‎(‎or plan to do so‎)‎‎,‎ you will find this book to be a valuable resource for getting up to speed on the state of the art‎.‎ Totally new material covers * Contexts of software architecture‎:‎ technical‎,‎ project‎,‎ business‎,‎ and professional * Architecture competence‎:‎ what this means both for individuals and organizations * The origins of business goals and how this affects architecture * Architecturally significant requirements‎,‎ and how to determine them * Architecture in the life cycle‎,‎ including generate‎-and‎-test as a design philosophy‎;‎ architecture conformance during implementation‎;‎ architecture and testing‎;‎ and architecture and agile development * Architecture and current technologies‎,‎ such as the cloud‎,‎ social networks‎,‎ and end‎-user devices‎.‎
