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
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 ... (more)
So You’re Renting Xen Condo’s in the Cloud, Big Deal, What’s Your Next
Here’s another quote from the article, “21 Experts Define Cloud
“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.”
I like this quote too – but for different reasons th... (more)
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)
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

Everyone’s busy abstracting resources in the cloud – making resources
like compute, stora... (more)
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)
