What is Complex Event Proce cessing (CEP)? � CEP is a technology that provides s us with means to define and detect specific logical events which ich might be made up of multiple physical events over a period of tim time. � Stateful event processing provides es us with “situation awareness,” ability to “sense and respond” and d “track and trace.” � Why is CEP important, particularly ly in the context of SOA? � SOA promotes the usage of Ev vent Driven Architecture (EDA) and encourages the shift from b batch or pull oriented method of operation towards real-time, bu usiness-oriented, push methods of communicating. � Business processes themselve es tend to operate in an event- driven way. Consider insurance ce or banking industries for example where most of the acti ctivities are driven as results of customers actions. � Because of the overall shift tow ward EDA, having the capability to process events intelligently beco ecomes paramount and this is where CEP comes in.

Some practical and familiar use cases can be listed as: s: � Medical pandemic detection � Fraud detection � Intrusion detection � Algorithmic trading � Traffic hotspots detection � RFID based shipmen/arrival/sa sales patterns � Stock trading patterns � Organizations are increasingly ado dopting EDA as a platform to effectively manage the increasing n g number of events generated from IT systems, business processe sses and physical sensors such as RFID
