IBM has a new product: WebSphere Business Events.
WebSphere Business Events (press release) is a new member of the WebSphere Business Process Management set of products, our SOA and ESB products like WebSphere Process Server. WBE enables an application to detect events and react to them by performing actions. It can wait until multiple events occur before reacting, which it does by performing complex event processing (CEP). The fact that there are events to detect and the ability to react to those events assumes that the application has at least a simple event-driven architecture (EDA). As its name implies, WBE approaches events as being business events, which means that the events are meaningful to the enterprise's business domain, so it performs business event processing (BEP).
The WBE event processing engine runs in WebSphere Application Server (included as part of WBE) and therefore runs on most any platform WAS runs on (but not System z or iSeries). WBE also includes development tools and runtime displays.
There's also an InfoCenter, the WebSphere Business Events Information Center.
