In this demo, a scenario is shown where multi-tenancy is enabled for a existing single tenant credit check service by introducing a WebSphere Enterprise Services Bus based mediation pattern. This pattern uses a WebSphere Enterprise Services Bus mediation module to perform two functions: Authorize access to the credit check service and route service invocations from a tenant bank's user to endpoints dedicated to that tenant. The endpoints are registered in WebSphere Service Registry and Repository for dynamic lookup based on a tenantID parameter in the service invocation context. Authorization policies are kept to Tivoli Access Manager.
