A Closer Look at Apama’s Economic News Alerts
If you haven’t noticed, Apama is doing some interesting things in the CEP space toward future event correlation. I have been closely following their partnership with Dow Jones to support their elementized news feed. Let’s take a closer look. The Apama screenshot, Economic News Alerts, highlights three or four top level tabs: Welcome; News based momentum [...]
Read moreEDA Visualized
Below is a graphic I put together for my September Gartner presentation, Getting Started in CEP: How to Build an Event Processing Application, called “EDA Visualized.” In this graphical representation of EDA, we show the sense-and-respond model around the functional CEP/EP reference architecture. I have slightly modified the traditional view of “Sense – Analyze – [...]
Read moreCEP and Rules Reloaded
Wait a few moments for the file to download and see what Neo-Architects have to say about CEP…. I know you’re out there. I can feel you now. I know that you’re afraid… you’re afraid of CEP. You’re afraid of change. I don’t know the future. I didn’t come here to tell you how this [...]
Read moreBrandl and Guschakowski Deliver Excellent CEP/BAM Report
Hans-Martin Brandl and David Guschakowski of the University of Applied Sciences Regensburg, Faculty of Information Technology/Mathematics, have delivered an excellent CEP thesis, Complex Event Processing in the context of Business Activity Monitoring, to their advisor Dr. Rainer v. Ammon. In their report they examined a BAM application using CEP concepts to implement what they referred to as [...]
Read moreRules Engines and Bayes’ Theorem
Charles Young kindly calls out my blog post, Bending Rules for CEP, and the discussion on rules and Bayesian analytics in his post, Rules Engines and Bayes’ Theorem. FWIW, implementing a very simple Bayes network with a rules engine, as in Charles interesting example, does little to counter the argument that rules engines are not an efficient implementation [...]
Read moreEvent Transformation Services
In my last post, CEP Event Sources, I started a (short) list of event sources, both in theory and in practice, for complex event processing. There were some good comments and the list is evolving and improving. Event transformations are used to convert inbound event objects to an outbound object type required by a transport [...]
Read moreCEP Event Sources
In this post we start to list different event sources for CEP applications. I will start with a broad classification, following the probe architecture by IBM’s NetCool OMNIbus, provide examples, expand and elaborate adding market data feeds, and other event sources that come to mind. We will expand the list based on comments. Also, we [...]
Read more7th Cyber Defense Initiatives Conference, Bangkok, Thailand
Last year around 900 people attended one of the largest cybersecurity events in Asia, the 6th Cyber Defense Initiatives Conference, Bangkok, Thailand, with folks attending from the around the entire APAC region. This year the 7th Cyber Defense Initiatives Conference, Bangkok, Thailand will be the week of November 22nd and 23rd. The program committee is [...]
Read moreCEP Myopia
Those with myopia see nearby objects clearly but distant objects appear blurred. Nearsightedness tends to run in families and usually appears in the early stages of life. It is a vision problem experienced by up to about one-third of the population. Nearsighted people have difficulty seeing the full picture, but can see up-close applications. Myopia [...]
Read moreInteresting CEP Use Case by Mark Hapher of Sun Microsystems
Mark Hapner of Sun Microsystems contributed a very interesting CEP use case to our event processing reference architecture working group (EPRAWG) based on RSS/Atom processing, titled: RSS and Atom – Event Based Computing for Global Applications Mark Hapner, Distinguished Engineer – SOA Strategist, Sun Microsystems To summarize, Mark says, “Long before the Internet, event based [...]
