So You’re Renting Xen Condo’s in the Cloud, Big Deal, What’s Your Next Act? Here’s another quote from the article, “21 Experts Define Cloud Computing” “The ‘cloud’ model initially has focused on making the hardware layer consumable as on-demand compute and storage capacity. This is an important first step, but for companies to harness the power of the cloud, complete application infrastructure needs to be easily configured, deployed, dynamically-scaled and managed in these virtualized hardware environments.” Kirill Sheynkman I like this quote too – but for different reasons than may be first apparent.  We’re watching something evolve at light speed; the cloud.  And the definition above is now taken for granted.  I should be able to dynamically, upon request, add stuff to my compute environment.  Big deal.  How do we take advantage of it?  There’s a big difference...

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)

An Unabashed Plug for Ulitzer

New Media on Ulitzer I was recently introduced to this site. And I like it a lot. You can check out my contributions there by clicking on this link. Also please see CEP on Ulitzer. ... (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...
