Cloud Expo on Ulitzer
I was speaking with a company last week that would like to get into cloud
event processing. For the sake of discussion, I’m going to define
‘cloud’ as the ability to dynamically, and upon demand, use more or less
compute, storage, or network capacity. This is often referred to as
‘elasticity.’ I’m also going to add a few other requirements; this
cloud must be able to:
Host operations for a number of customers, all accessing the same data, but
in different ways, Provide access to a lot of big data (see #3 – it’s all
stored too), Able to handle messages rates approach 1MM per second (yes,
that’s a million messages per second), Do something with those messages
before storing them (in fact, we’re not even worried about storing them),
And while we’re doing something with those messages, relate them to
previously stored messages.

Cloud Event Processing has moved off the white board and into the real world
of, ‘hey, we’ve got customers!’
When building a system like DarkStar, one can always run into difficulties
– how does one demo a cloud based, distributed event processing system
incorporating streaming map/reduce, complex event processing, and event
driven pattern matching agents to prospective customers? Our background
includes very high velocity feeds, like equities and option market data
feeds, but using those for demo purposes can be difficult. So we decided on
using Twitter. We decided ... (more)
CEP isn’t really about low latency. The ability to do things quickly is
important, just as in any system – especially those systems that grow and
need to handle a lot of information. Doing things quickly means doing
things efficiently. And doing things efficiently means less money spent on
hardware. Theoretically anyway.
SO WHAT IS REALLY COOL ABOUT CEP?
CEP gives one the to submit queries like “select symbol, avg(shares) from
trade_stream group by symbol over 5 minutes emit every 1 minute.” The CEP
engine would consume this query, and then start returning an average of
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)

I was recently introduced to this site.
And I like it a lot.
