You could adjust the original stock quote scenario to improve the governance of your services.
The life cycle of a service within a service-oriented architecture (SOA) requires governance processes. Governance processes ensure that standards and policies are enforced, and that change occurs in a controlled fashion and with the appropriate authority.
You can use the IBM® WebSphere® Service Registry and Repository (WSRR) with the ESB, to improve governance.
The original business requirements of the stock quote scenario did not include life cycling, or versioning, of stock quote services. However, as the financial services company grows, life cycle management might become a high-priority requirement. For example, to comply with audit requirements, or because the company starts to provide services for other companies.
Version 1.2 of the stock quote scenario requires the storing of service endpoints in a registry. When services are stored in a registry, life cycle management becomes easier and more secure.
The service endpoints must be added to the registry, and a custom property created for the use of the stock quote mediation module. The custom property represents the subscription level used by the stock quote mediation module.
