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...

Cloud vs Grid

IBM Session at Cloud Expo I’ve been getting a lot of email, and there have been some posts on this blog, regarding CEP based services in the cloud. So as we go down this road, I thought it would behoove us to examine what a cloud is and isn’t and what a grid is and isn’t. I found this introductory article from IBM.  It’s a good start.  I’ll be looking for some more articles – if you’ve got anything you’d like to add to this conversation, please feel free to contact me or add your comments below. Personally, my experience with grid comes from Capital Markets and calculating pric... (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...

Cloud Event Processing – Where For Art Thou oh CEP?

In a recent post, Louis Lovas of Progress Apama explains why the first generation CEP vendors don’t have many, if any, cloud deployments.  Here’s a quote from his post: Typical of event processing applications that do things are those in Capital Markets like algorthmic trading, pricing and market making. These applications perform some business function, often critcal in nature in their own right. Save connectivity to data sources and destinations, they are the key ingredient or the only ingredient to a business process.  In the algo world CEP systems tap into the firehose of da...
