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. This can bring major benefi... (more)

How do you know that it will scale to accommodate future needs? How do you know that you can actually get the business flexibility that SOA ... (more)

One of the essential characteristics of cloud computing is "measured service." Resource usage ... (more)

Learning from SOA Mistakes

Today, global businesses are increasingly turning to Service Oriented Architecture (SOA) for their information technology infrastructure and applications. SOA is becoming an increasingly practiced approach to building software solutions as it can support integration and consolidation of activities in complex enterprise systems. This year the percentage of functioning SOAs has almost doubled, according to Evans Data Corporation's latest Web Services development survey: "Twenty-four percent of respondents (the sample data set being 400) are saying they currently implement SOA, an ...
