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 data, and the data rates
in these markets (Equities, Futures & Options, etc.) is increasing at a
dizzying pace. CEP-based trading systems are focused on achieiving the lowest
latency possible. Investment banks, hedge funds, and others in the arms race
demand the very best in hardware and softw... (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)
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

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

calculating pric... (more)
Over the past few weeks, I’ve implemented map/reduce using techniques
commonly found in Complex Event Processing. Here’s a summary of what was
involved, and what tools would make such a deployment easier.
Getting the Data
One of the first tasks accomplished was the creation of an OnRamp – we use
OnRamps to get data into our cloud for processing. The specific OnRamp used
in this learning exercise subscribed to Twitter and fed the resulting JSON
objects onto the service bus, RabbitMQ in this case. We had to correctly
configure RabbitMQ for this, and the OnRamp needed to be specif... (more)
