Which of the following statements best describes how the deployment supports closed-loop
governance?
A.
The Metadata Repository is integrated with the operational systems to link operational metrics
to the assets to ensure that the assets perform asintended.
B.
The Metadata Repositories deployed in each environment are chained to share asset usage
information.
C.
A closed-loop governance framework is deployed on a clustered server to monitor the
governance activities.
D.
Production systems are integrated to the developer desktops to validate the requirements
against the implemented code.
Explanation:
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.
