The Art of the Service-Oriented Architecture: Flexible and Nimble IT

There was something harmonically convergent about some of the issues being discussed, however, particularly in light of several new products IBM announced today regarding our service-oriented architecture strategy (better known in industry parlance as "SOA"). For those of you less familiar with the SOA concept, or what it represents, let me briefly characterize it, then promptly pass you along to some key IBM resources related to our announcement where you can get more familiarized with the concept and IBM's SOA roadmap.
First, a quick look at the key on demand business drivers. Many organizations today, by force of an insanely competitive business environment and the need to maximize the return of every dollar invested, need to increase their business flexibility so that they can grow or contract their business based on customer demand. They also need better and more timely (read: integrated) access to information, so that they can both respond to external threats and take advantage of emerging market opportunities. IBM's Business Consulting Services team discovered in a recent survey that 90% of CEOs expect to make a transformation to provide such capabilities within the next 5 years.
Unfortunately, many existing IT systems were not architected with such flexibility in mind. They were vertical building blocks (infrastructures, applications, etc.) that often sprouted up in isolation of one another, serving a very specific purpose at a very specific point in time. Nothing wrong with them -- they just evolved under very different business conditions and externalities than the more discordant environment that many organizations face today.
SOA is about reorganizing information resources to be independent, reusable services -- ones built in an inherently adaptable environment and architected with open, standard protocols that allow them to be used independently of their underlying platforms. In other words, built using standards that allow interoperability and the ability to be more easily evolved and reused, and most importantly, created in the context of specific business processes. That way, like IT LEGOs, they can be mixed and matched to more readily address specific business problems or conditions that can emerge suddenly, and often with no significant warning. Think new market entrant, the influx of a major and demanding customer, or yes, even a hurricane. You are only as flexible as your IT infrastructure is adaptable.
