The Predictive Battlespace

June 11, 2008

Friend and colleague Don Adams, CTO World Wide Public Sector, TIBCO Software, explains how CEP can be used to sense, adapt and respond to complex situations in The “Predictive” Battlespace: Leveraging the Power of Event-Driven Architecture in Defense

More on CEP Maturity: Capability Versus Reliability

June 3, 2008

Louis Lovas of Progress Apama wrote a complimentary blog entry on the topic at hand, CEP Maturity Models.   In his post, Louis says:

“What a CEP platform has tracks independently of what it is capable of doing. ….. What CEP does, is likely what Tim is referring to when he states we’re in the Technology Trigger phase.”

Peter Lin’s comment, in reply to Louis, concurs:

“Given that COTS CEP has only been around a few years, I think it is safe to say it’s still in the early phase. If we compare it to messaging middleware, which has been around for more than 15 years, CEP isn’t as mature. Another comparison is business rule engines and expert systems. The earliest business rule engines date back to late 80’s. All things considered, I would agree with Tim. COTS CEP still has a lot of time to mature.”

Louis was spot on when he said that I was focused on overall CEP functionality; not individual product reliability.

Independent of how reliable a particular CEP-type application might appear; the overall state-of-the-art of CEP is really quite immature.



On CEP Maturity and the Gartner Hype Cycle

June 1, 2008

In reply to Mark Palmer’s rebuttal, What Does it Mean to be Mature?, the figure below illustrates the popular Gartner Hype Cycle.  You can click on the illustration to get a clearer image.

In context to the Gartner Hype Cycle, CEP is closer to the “Technology Trigger” phase than anywhere else in the hype cycle.  CEP has not yet reached the “Peak of Inflated Expectations”, but is inching closer and closer.

In addition, as a correlating reference point, if you look at a recent Gartner Hype Cycle that covers EDA, for example, you will find that EDA  (Event Driven Architecture) is at a similar phase, the “Technology Trigger” phase.
