What problem does this solve?
Web services do not inherently provide an SOA
• Must provide coordination, visibility, and manageability across those services

What are the key differences?
Versioning at the endpoint or operation level
Policy application at the endpoint or operation level
Driven from a common service model or proprietary data store
Start Making Investments
Invest in an Enterprise Service Model
• Traditional models reflect real-world objects and behaviors.
• The ESM should be reality! The model is the application!
Invest in Service Virtualization with support beyond Contract Optimization.
Invest in Service Virtualization with support down to the Operation Level.
