Explanation/Reference:
SOA Software's Policy Manager and Service Manager combine to form a comprehensive closed-loop SOA Governance solution.
Closed loop means:
* Defining and managing actionable policies in a governance solution at design-time
* Enforcing these policies via deep integration with a management solution at run-time
* Auditing that these policies are being enforced
* Using industry standards (WS-Policy, WS-MEX) where appropriate for information exchange Closed loop infrastructure enables demand and Value Management
* Collect performance, usage and exception statistics at run-time
* Track these statistics via the governance solution
* Use live, audited information to drive value-based decisions about the effectiveness of different services and organizations
* Provide developers with up to the minute information about a service in runtime to inform their decisions about which services to use
* Manage supply and demand to ensure maximum efficiency and benefit from SOA The products share a common registry and metadata repository to ensure seamless integration and offer active governance. Closed-loop governance will:
* Ensure defined policies are enforced
** When you define a policy for a service you have to KNOW categorically that it is being enforced
** Generate audit trails for run-time and design-time policy compliance
* Measure the real-world value of SOA
** Not just theoretical value
** How many applications are using each service, and how much are they using it
** NOT how many applications have asked to use a certain capacity of each service
* Manage, monitor and control relationships between consumers and providers
** Enforced contracts
** Capacity planning Change management
The diagram below shows the relationships between SOA governance, security and management, demonstrating how SOA Policy Management forms a closed loop of policy, metrics, and audit.
