Working the event horizon [Systems Event-Driven SOA]

The best-laid plans of any IT strategy can get derailed by unforeseen factors wrong-footing critical application outcomes. However, the author finds that event-driven systems are built to take change in their stride. IT systems are mostly built around the idea that things happen in predictable sequences. Everything else is an exception to be squashed. But that is an approach that is beginning to change as IT directors realise that real-world events are not troublesome inputs but actually provide a way to drive their systems. Event-driven architecture is relevant to any business that has multiple parties involved. People are not used to building architecture because they typically work with in synchronous environments today.
