Service-oriented architecture: concepts, technology, and design
Using Service-Oriented Architecture (SOA), enterprises can deliver high-value business services more rapidly and effectively, and gain unprecedented flexibility and value from existing IT infrastructure. SOA has earned the support of virtually every major software provider, and some 75% of enterprises surveyed are now investing in SOA technology and expertise. In 'Service-Oriented Architecture - Concepts, Technology, and Design', the author presents the first end-to-end-tutorial for modeling and designing successful service-oriented architectures from the ground up. Writing in plain English, Thomas Erl provides step-by-step process descriptions for analyzing and designing any service or service-oriented business process definition. Drawing on his unsurpassed experience as an SOA architect, Erl uses more than 125 case studies and 300 easy-to-understand diagrams to illuminate every facet of the SOA platform - goals, concepts, technologies, standards, and design best practices.
