Bus-enabled Web services - frequently asked questions

Answers to a set of frequently asked questions about the Web services enablement of the service integration bus.

What are Web services?

Web services are modular applications that interact with one another across the Internet. Web services are based on shared, open and emerging technology standards and protocols (such as SOAP, UDDI, and WSDL) and can communicate, interact, and integrate with other applications, no matter how they are implemented.

What are bus-enabled Web services?

Bus-enabled Web services is a software component that enables your Web services to use service integration technologies. Bus-enabled Web services provides a choice of quality of service and message distribution options for Web services, along with intelligence in the form of mediations which allow for the rerouting of messages.

How do bus-enabled Web services enable your Web services?

You can use bus-enabled Web services to achieve the following goals:
  • You can take an internally-hosted service that is available at a bus destination, and make it available as a Web service.
  • You can take an external Web service and make it available internally at a bus destination.

What problems are solved by bus-enabled Web services?

Bus-enabled Web services solve the following problems:
  • Securely "externalizing" existing services: Existing business applications that are exposed as Web services can be used by any Web service-enabled tool, regardless of the implementation details. Bus-enabled Web services also let you enable controlled access for clients from outside the firewall to Web services that are hosted within your enterprise.
  • Better return on investment: Any number of partners can reuse an existing process that you deploy as a Web service.
  • Use of existing infrastructure: You can use your existing messaging infrastructure to make Web service requests, and use your existing Web services for external process integration.
  • Use of external Web services: You can make an existing external Web service available to your internal systems at a bus destination.

Who should use bus-enabled Web services?

Any enterprise that chooses to share its resources selectively with its business partners and customers. IT managers and developers, who deploy resources, can also benefit from this technology.
