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 predictions I’d made earlier after the benefit of some quality thinking time. So here they are: Cloud based services will finally hit Wall Street in 2011. It makes a lot of sense for firms to offer shared access to things like market data and to provide elastic resource for its manipulation. It d... (more)

Building a Back Testing Platform for Algorithmic Trading

On this continuing series, I am examining thoughts and specific implementation details around building a back-testing platform for algo trading.  Eventually, we’ll see where complex event processing plays and how to implement it. Appendix to Part One – The Data Format Rather than looking at various database solutions first and then trying to define the problem in terms of those solutions, let’s first examine what market data looks like.  In its most simple form, market data looks like this (there’s usually a little more, but this is fine for our purposes): Date: The date of the ...

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)

Just When I Thought I Was Done… Bring on the Visualization!

“They pulled me back in.” – The God Father. I’ve received some interest/emails about TwitURL – our Map/Reduce as it applies to CEP (cloud event processing) project.  Seems that people would like to see the results of these processes visually.  Who can blame them, right?  So, I was thinking, how can I add a little sizzle to TwitURL? Panopticon Panopticon offers some pretty slick visualization capabilities – you can check them out here.  And based upon some feedback/requests, I’m going to hook up a heat map to the output of TwitURL.  The heat map will show which URL’s are the hott...

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)
