The Gartner Symposium/ITxpo 2009 we have been attending in Orlando not only endorsed the big hypes aroung virtualization and cloud computing, but also our ongoing investments in service-aware process automation – offering real-time intelligence for just-in-time execution. It matched perfectly that Gartner analyst Roy Schulte and K. Mani Chandy, Professor at the California Institute of Technology in Pasadena, used this event to introduce their brand new book called “Event Processing: Designing IT Systems for Agile Companies” about the business drivers, costs and benefits of event-processing applications.
According to Mr. Schulte and Mr. Chandy the new aspirations in situation awareness and reaction accuracy can`t be achieved by simply speeding up traditional business processes or exhorting people to work harder and smarter with conventional applications. Instead they urge companies to make fundamental changes in the architecture of business processes and the application systems that support them by using more of the event-processing discipline. “While a typical business process has time-driven, request-driven and event-driven aspects, event-driven architecture (EDA) is underutilized in system design resulting in slow and inflexible systems,” said Mr. Chandy. “Event-driven systems are intrinsically smart because they are context-aware and run when they detect changes in the business world rather than occurring on a simple schedule or requiring someone to tell them when to run.”
“Event-driven CEP is a kind of near real-time business intelligence (BI), a way of `connecting the dots` to detect threats and opportunities,” explained Mr. Schulte. “By contrast, conventional BI is time-driven or request-driven. Complex events may be reactive, summarizing past events or predictive, identifying things that are likely to happen based on what has happened recently compared with historical patterns.”
