SOA Modeling Patterns for Service-Oriented Discovery and Analysis As hot as SOA is today, many business and technology professionals still find it challenging to join together their various methodologies and objectives. What directions should guide you in identifying new services, analyzing your technological capabilities, and proposing a superior architecture solution? And, how should you model an analysis proposition for a small-scale project or a large enterprise initiative? Author Michael Bell's previous book, Service-Oriented Modeling: Service Analysis, Design, and Architecture, introduced Service-Oriented Modeling Framework (SOMF) software development methodology and simple SOA Modeling patterns designed to overcome the communication barriers between business and IT professionals. Now, Bell continues the conversation with SOA Modeling Patterns for Service-Oriented Discovery and Analysis. The patterns provided here offer road-tested analysis, discovery processes, and design solutions to assist you in devising an Analysis Proposition, a modeling artifact that offers a remedy to business or technological concerns. Reflecting the author's years of SOA knowledge and experience, this authoritative guide for service-oriented projects offers straightforward, focused answers to the challenging questions that come up during the development process to equip you to: <ul> <li>Analyze the problem domain</li> <li>Discover services</li> <li>Analyze services for construction and production</li> <li>Assess service feasibility for deployment</li> <li>Employ the SOA modeling language during the service identification and examination process</li> <li>Identify services and analyze proposed business and technological solutions</li> <li>Utilize the SOA modeling patterns and anti-patterns for service discovery and analysis</li> </ul> An essential business and technology service-oriented modeling road map for you—whether you are a manager, architect, modeler, analyst, or a developer—SOA Modeling Patterns for Service-Oriented Discovery and Analysis empowers your organization with the necessary tools and terminology to develop services that deliver the benefits of SOA. This guide also offers implementation and design best practices for Enterprise 2.0. This is the next SOA generation that has picked up steam recently. The introduced modeling language will assist you with developing a powerful business and technological strategy for SOA Implementations, Virtual Modeling Ventures, and future Cloud Computing Projects.
