The Evolution of SOA Hinges on an Open Marketplace for Services

The law of far-reaching effects

We can't foresee the full potential of Service Oriented Architecture any more than Henry Ford could have foreseen the scale of today's automotive industry when the first Model T rolled off the production line nearly a hundred years ago. But there are signs that it will be equally far-reaching. If so, this will because of the same force that made Ford rich: the open market.

Service Oriented Architecture (SOA) is an architectural style in which the software applications are organized as loosely coupled services. It's being adopted by many enterprises today because it results in agile IT systems that are easier to adapt to change. But it has another capability that could be more important. It lets an enterprise use externally provided services and choose between similar services provided by different suppliers. It enables market competition.
