Part One: Knowing the Beast
One of the most complex and dramatic characters of a circus is the animal trainer;
one who can face a bevy of threats when dealing with a strong and wily beast,
like a tiger. Think of the tiger as an example of the circus'raison d'etre.
In information technology, the tiger is that most promising platform for applications:
Service Oriented Architecture.
The tiger is a dynamic, powerful, complex, living organism; comprising integrated
systems, just like a SOA environment. Applications are the lifeblood of a business.
You wouldnt let your toddler wander around in the cage with an unmanaged
tiger; why would you risk your business by letting your applications run in
an unmanaged SOA environment?
The tiger (SOA environment) is dependent on the trainer for its care, feeding,
and well being. The trainer (user) depends on the tiger to behave in expected,
predictable, and consistent ways. If there's a hint of inconsistency in the
tiger's behavior or reactions, the trainer better be able to spot it and react
fast or lose body parts.
If the tiger has been distracted by ladies in large straw hats or sudden loud
noises in the past, it's crucial for the trainer to know this. If a straw-hat
lady walks in or if a thunderstorm comes up, he must be prepared to proactively
deal with these events with a combination of real-time and historical trend
data to take preventive action before the tiger runs amok
While information systems are the lifeblood of an enterprise, even the seemingly
simplest of applications (like buying or selling shares of stock) may depend
on many, different streams of information. They must not merely handle these
streams of information efficiently, but also intelligently and within the appropriate
compliance requirements.
The value of information is negatively affected by age, as measured in fractions
of seconds. More importantly, it can also be valued according to its source.
Both the timeliness and source of information depend upon a complex stream of
raw data from trading partners, RSS news feeds, financial data from news sources,
the Federal Reserve and perhaps even weather information.
