Routing policies can be applied so that when, for example, an error occurs when attempting to invoke the target service on the selected endpoint, traffic can be dynamically re-routed to an alternative endpoint.
Routing information can be retrieved from WSRR at runtime, both DataPower and IIB can route to endpoints registered in WSRR rather than coded in the application.
- Combining IBM Integration Bus with WSRR
Combining IBM Integration Bus with WSRR (WebSphere Service Registry and Repository) enables message flows running in IBM Integration Bus to access the metadata associated with services registered in WSRR. This enables dynamic connectivity between service consumers and service providers.
Parts 3 and 6 of the article series shows how to route messages to endpoints defined in WSRR, from an IIB flow. Part 3 describes how content based routing can be used to select a service provider, based on content of the original message. Part 3 also shows how to dynamically route to an different endpoint if an error occurs when invoking a service.
- Using WebSphere Service Registry and Repository V8 and DataPower V5 for service level mediation policy enforcement
This article shows you how to create a web service proxy in WebSphere DataPower for a web service registered and governed in WebSphere Service Registry and Repository. It also shows you how to attach a service-level mediation policy to the service in WebSphere Service Registry and Repository and then enforce it in DataPower.
This article shows you how to create a proxy in DataPower that dynamically looks up the endpoint to use from WSRR, for SOAP over HTTP services.
- Using DataPower with WSRR and REST services, Part 1: Registering, exposing, and invoking a REST service with a sample client
This article shows you how to use new capabilities in DataPower V6 and WSRR V188.8.131.52 to dynamically look up endpoint URLs of REST services that are registered in WSRR. Policies authored and stored in WSRR and enforced by DataPower have also been enriched with new capabilities.
This article shows how to create a proxy in DataPower that dynamically looks up the endpoint address for REST over HTTP services.
