Pattern-Oriented Software Architecture, Volume 4, A Pattern Language for Distributed Computing (eBook, PDF)

• Format: PDF

Produktbeschreibung

The eagerly awaited Pattern-Oriented Software Architecture (POSA) Volume 4 is about a pattern language for distributed computing. The authors will guide you through the best practices and introduce you to key areas of building distributed software systems. POSA 4 connects many stand-alone patterns, pattern collections and pattern languages from the existing body of literature found in the POSA series. Such patterns relate to and are useful for distributed computing to a single language. * The panel of experts provides you with a consistent and coherent holistic view on the craft of building distributed systems. * Includes a foreword by Martin Fowler * A must read for practitioners who want practical advice to develop a comprehensive language integrating patterns from key literature.
