CEP: Correlation and Orchestration

• Developed at Stanford University in the mid-1990’s

• DARPA grant• Theory of activity correlation

and orchestration via new “Event Pattern | Condition | Action” paradigm

“The goal of CEP is to enable the information contained in the events flowing through all of the layers of the enterprise IT infrastructure to be discovered, understood in terms of its impact on high level management goals and business processes, and acted upon in real time.”

Professor David Luckham
