Service integration topologies

This topic provides information about the service integration topologies that you can configure. A service integration topology can range from a single host running two connected applications to a globally-dispersed set of hundreds or thousands of communicating applications running over the bus.

A service integration topology is based on one or more service integration buses that provide a managed communication fabric that supports service integration through synchronous and asynchronous messaging.

A service integration bus supports applications using message-based and service-oriented architectures. A bus is a group of one or more interconnected servers that have been added as members of the bus. Applications connect to a bus at one of the messaging engines associated with its bus members.

The following capabilities are provided by a service integration bus:

The service integration bus is sometimes referred to as the messaging bus if it is used to provide the messaging system for JMS applications using the default messaging provide.

Many scenarios require a simple bus topology; perhaps, for example, a single server. By adding multiple servers to a single bus, you can increase the number of connection points for applications to use. Servers, however, do not have to be bus members to connect to a bus. In more complex bus topologies, multiple buses are configured, and may be interconnected to form complex networks. An enterprise might deploy multiple interconnected buses for organizational reasons. For example, an enterprise with several autonomous departments might want to have separately administered buses in each location.

Through the service integration bus Web services enablement (SIBWS), you can achieve the following goals:
You can change the service integration topology to suit your needs; for example:
