The Expert, Practical Guide to Succeeding with SOA in the Enterprise

In Executing SOA, four experienced SOA implementers share realistic, proven, “from-the-trenches” guidance for successfully delivering on even the largest and most complex SOA initiative.

This book follows up where the authors’ best-selling Service-Oriented Architecture Compass left off, showing how to overcome key obstacles to successful SOA implementation and identifying best practices for all facets of execution—technical, organizational, and human. Among the issues it addresses: introducing a services discipline that supports collaboration and information process sharing; integrating services with preexisting technology assets and strategies; choosing the right roles for new tools; shifting culture, governance, and architecture; and bringing greater agility to the entire organizational lifecycle, not just isolated projects.

Executing SOA is an indispensable resource for every enterprise architect, technical manager, and IT leader tasked with driving value from SOA in complex environments.

Coverage includes

·  Implementing SOA governance that reflects the organization’s strategic and business focus

·  Running SOA projects successfully: practical guidelines and proven methodologies around service modeling and design

·  Leveraging reusable assets: making the most of your SOA repository

·  Enabling the architect to choose the correct tools and products containing the features required to execute on the SOA method for service design and implementation

·  Defining information services to get the right information to the right people at the right time

·  Integrating SOA with Web 2.0 and other innovative products and solutions

·  Providing highly usable human interfaces in SOA environments
