This document summarizes a presentation on service virtualization. It discusses how service virtualization addresses problems with tightly coupled web services by providing coordination, visibility and manageability across services. It presents service containers and service intermediaries as two implementation options for service virtualization. Key differences between the options are that service containers abstract the environment from the service implementation, while service intermediaries abstract the service client from the service implementation. The presentation encourages investments in an enterprise service model and service virtualization capabilities beyond just contract optimization.

What problem does this solve?
 Web services do not inherently provide an SOA
• Must provide coordination, visibility, and
manageability across those services
• Tightly coupled implementations are difficult to
change

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.
