Top Stories by Colin Clark

In the past year or so, I’ve heard from many skeptics – people who didn’t believe that Event Processing could be successfully deployed in the cloud.  Granted, most of these folks represented firms actively engaged in providing the High Frequency Trading (Algo Trading) industry with tools.  And in that arena, cloud deployment probably doesn’t make sense.  Yet. Close to Home Though Ask people in Capital Markets about Twitter and the most common response you’ll get is, “What do people use it for?”  This is because most of the people in Capital Markets can’t use things like Twitter, instant messaging, or Facebook at work and if they can, it’s heavily regulated.  But the point is, that they mostly don’t get it – I myself was included in this camp until a friend of mine explained it to me.  Since thing, I’ve taken to Twitter like a fish to water.  My point here is that the...

CEP in the Cloud

I’ve spent the last couple of days, after absorbing the Sybase acquisition of Aleri’s assets, looking at the various CEP players websites for evidence of cloud (grid name du jour) deployment. I haven’t found anything worth mentioning.  That’s not to say that I might have missed something.  But my guess is that with all the economic woes lately, that the CEP vendors have either chosen to ignore or just simply aren’t aware that the rest of the world is actually solving real problems with cloud deployments. Which is interesting. It’s interesting because one of the pioneers in CEP &... (more)

Why CEP in the Cloud Makes Sense

CEP isn’t really about low latency.  The ability to do things quickly is important, just as in any system – especially those systems that grow and need to handle a lot of information.  Doing things quickly means doing things efficiently.  And doing things efficiently means less money spent on hardware.  Theoretically anyway. SO WHAT IS REALLY COOL ABOUT CEP? CEP gives one the to submit queries like “select symbol, avg(shares) from trade_stream group by symbol over 5 minutes emit every 1 minute.”  The CEP engine would consume this query, and then start returning an average of sh...

Data Mining in Streaming Data

Lately, I’ve been working on some interesting projects involving not just the usual suspects of stream processing, but data mining within high velocity time series.  In conjunction with that effort, I’ve been doing a lot of research in the areas of symbolic representation, dimension reduction, clustering, indexing, classification, and anomaly detection.  A prolific  researcher in this area is Dr. Eamonn Keogh – I’ll be applying some of his team’s ideas so some interesting customer problems and telling you all about it here.  Let’s get started! TOO MUCH DATA In dealing with real... (more)

My Top Five Cloud Predictions for 2011: Colin Clark

Every year, I like to decompress a bit and take a break. Usually, I like to go scuba diving – the dive sites I like are usually far removed from email, Twitter, Facebook, etc. and it gives me a chance to actually unplug, defrag, and think a bit. This year, the family went to Grand Cayman to experience some of the world’s best diving. Within Grand Cayman is Hell, a small township dedicated to tourism and aptly named given the attached photo. We visited Hell in between dives, and rather than make my ex-wife room reservations or send out postcards, I thought I’d amplify a few predic... (more)
