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 prices & greeks for derivatives. think that some of the people reading this blog might be mistaking what I’m talking about when I say, “Current CEP products don’t seem to be a good fit in the cloud.” think that those people with Capital Market’s experience think grid when I say cloud, and think ...

Cloud Aware or Cloud Built

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 th...

Writing Bad Code in Map/Reduce

In the Twitter project we’ve been working on, one of the map’s we’re running breaks the text of a Tweet down into words. Because we can’t assume that any data will be available for access via a database, etc, we attach a couple of values that we’re interested for later analysis to the word, attach a 1, and emit the tuple. This is an example of what the tuple looks like: "TimeZone", "Location", "ScreenName", "Word", 1 This map is produced from a tweet that contains many words, so, crunching the Tweet down will result in many of the above values being duplicated. "TimeZone", "Locati... (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)

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)
