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 & database space, Mike Stonebreaker (love that name), has gone on to work in stealth mode (it says stealth on their web site anyway) over at VoltDB. VoltDB is based upon work done on HStore and would appear, on the surface anyway, to incorporate all of the things we’d expect in an OTP environ... (more)

Real CEP – Cloud Event Processing

Ok, so if you’ve been following along, you’ll already know: Installed RabbitMQ, and Written a Twitter OnRamp that subscribes to a sample Twitter feed and publishes it on RabbitMQ, and Written a RuleBot that takes the tweet and breaks it into chunks, putting the chunks back onto the bus. And now I’m going to show the Esper code that gives us the top URL’s in the last X seconds found in the Twitter feed.  Here’s a screenshot. Here’s some output in text mode (easier to read): Event received: {URL=http:\\cnn.com, Total=731} Event received: {URL=http:\\colinclarkeventprocessing.com, Tot... (more)

CEP & RuleBots & OnRamps – Oh My!

I like Streambase’s announcement regarding their open source repository for CEP related stuff. And imitation is the sincerest form of flattery, so I thought I’d follow suit. In my glossary of terms, I deal with RuleBots and OnRamps. RuleBots RuleBots are pieces of code that subscribe to streams, do something of interest, and then put a result back on a stream. We’re releasing RuleBots with logic pertaining to Regulation NMS surveillance rules in the areas of: Trade Through, Unusual Activity, NBBO Calculator, Late Trading, Front Running, Wash Sales, Short Sales, Locked/Crossed, a...

IaaS and Building a Private Cloud

Cloud Expo on Ulitzer I was speaking with a company last week that would like to get into cloud event processing.  For the sake of discussion, I’m going to define ‘cloud’ as the ability to dynamically, and upon demand, use more or less compute, storage, or network capacity. This is often referred to as ‘elasticity.’  I’m also going to add a few other requirements; this cloud must be able to: Host operations for a number of customers, all accessing the same data, but in different ways, Provide access to a lot of big data (see #3 – it’s all stored too), Able to handle messages ra...

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)
