Top Stories by Colin Clark

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, Total=643} Event received: {URL=http:\\rabbitmqm.com, Total=636} Event received: {URL=http:\\cnn.com, Total=738} Event received: {URL=http:\\colinclarkeventprocessing.com, Total=651} Event received: {URL=http:\\rabbitmqm.com, Total=642} Event received: {URL=http:\\cnn.com, Total=742} Event rece...

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)

Erlang, RabbitMQ, & Redis

VMWare has been on a buying spree lately. In the last month, they’ve announced both Redis and RabbitMQ. Here’s VMware’s take on Redis, and spring source’s on RabbitMQ.  RabbitMQ is built with Erlang. Much Rejoicing in the Village We use both of these technologies at Cloud Event Processing.  And we love Erlang too.  VMware’s acquisition of these technologies not only validates our decisions, which we are very selfishly pleased about, but also sends an interesting message. The Message Please Everyone’s busy abstracting resources in the cloud – making resources like compute, stora... (more)

Event Processing in the Cloud – DataSift is a Big Proof Point

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, i...

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)
