The field of software architecture continues to grow in acceptance and importance. However, this burgeoning discipline has thus far lacked an authoritative treatment that helps its practitioners gain valuable perspective and a thorough understanding of the disparate viewpoints that project stakeholders bring to the project. In this new book written by two practicing software architects, the field of software architecture now has an invaluable resource for designing and implementing successful software architectures. Colleagues, business management, and ultimately customers appreciate the benefit of solid software systems architecture, and this new book helps the architect deliver it. This software architecture handbook will be referred to time and again. It is a single source of proven practices and valuable advice that will help the software architect shepherd a project through its entire lifecycle.
