The server and bus environment of WebSphere Process Server is
built on the service integration technologies of the underlying WebSphere Application Server.
Why and when to perform this task
The service integration functionality within WebSphere Application Server provides
a highly-flexible messaging system that supports a service-oriented architecture
(SOA) with a wide spectrum of quality of service options, supported protocols,
and messaging patterns. It supports both message-oriented and service-oriented
applications.
This messaging system is based on the concept of a
service
integration bus, which combines the messaging fabric and service-oriented
capabilities:
- A service-oriented infrastructure to support application description,
deployment, and invocation using the service-oriented architecture.
- Reliable message transport capability
- Both tightly and loosely coupled communications options
- Intermediary logic (mediations) to intelligently adapt message
flow in the network
- Implementation of relevant Web Services standards
You can configure service integration in a variety of different
ways; for example, to tailor the functionality to meet specific messaging
needs without needing specialized messaging point products.
Within WebSphere
Application Server, service integration provides:
- The default messaging provider as a J2EE 1.4 compliant JMS provider, fully
integrated with Application Server, supporting multi-server configurations,
and inter-operating with WebSphere MQ.
- The Service Integration Bus, which provides the first-class infrastructure
for Web Services integration of applications by leveraging the service-oriented
architecture based on Web Services standardization.
- Support for the Web services gateway, which provides you with a single
point of control, access and validation of Web service requests, and allows
you to control which Web services are available to different groups of Web
service users.
- The messaging infrastructure for On Demand Computing.
