Using Other Business Services, Processes, and Operations
Although the simplest ESB systems can consist of a production with only pass-through services and operations, some requirements can only be met with more complex production components. For example, if your ESB must do any of the following, you need other kinds of business services and operations:
-
Route calls from a single incoming service to multiple external services depending on the content of the call.
-
Modify the parameters or protocol used for a service.
-
Expose a single service that is implemented by combining the capabilities of two or more external services.
-
Provide the service directly on the ESB.
-
Provide security other than one based on SAML tokens.
