The Definitive Guide to SOA: BEA AquaLogic Service Bus targets professional software developers and architects who know enterprise development, but are new to enterprise service buses (ESBs) and service-oriented architecture (SOA) development. This is the first book to cover a practical approach to SOA using the BEA AquaLogic Service Bus tool. And it's written from the "source" - BEA Systems AquaLogic product lead Jeff Davies.This book provides hands-on information to developing SOA-driven applications with ESBs as central components. It also gives strategic guidance on SOA planning, web service life-cycle management, administration of an ESB, and security considerations. Author Jeff Davies is careful to cut through theory and get straight to demonstrating successful use of the product where SOA really counts.
