The original goal of the Service Oriented Architecture (SOA) concept was to build flexible, loosely coupled systems. But any two components in a system that communicate with each other are coupled to a certain extent. As architects, our aim in deploying real world SOAs is to lessen that coupling between components. That means removing or lessening the runtime dependencies between them. These two tenets of SOA, however, loose coupling and distributed resources, are a double-edged sword: along with the potential for much greater IT flexibility and business agility, they bring the potential for harder oversight. Considering that we live in a new regulatory environment that requires much more stringent oversight, monitoring and enforcement of corporate and IT governance policies, we need a mechanism to span the service lifecycle and provide an abstraction layer that is declarative, configurable and centrally managed. The required level of abstraction for SOA sits at the Policy level. Policies contain assertions about the operational interfaces for components in an SOA. These include credential preferences, authentication and authorization mechanisms, signature and encryption preferences, identity sources, routing, transformations, versioning, reliable messaging and others. This talk will introduce the concept of Policy Driven SOA and discuss Policy, its role in SOA Governance, and the WS-Policy specification as the new contract abstraction for SOA.

Service-oriented architectures (SOAs) have evolved over the past few years out of the original vision of loosely coupled web services replacing constrained, stovepiped applications throughout enterprise IT. Every major enterprise technology vendor today has developed its own SOA strategy, supported by innumerable mid-size companies and start-ups offering specific SOA aspects or entire solutions. This explosive growth in SOA technology is in response to a global demand--IDC estimates that spending on SOA services alone will grow from $8.6 billion to more than $33 billion by 2010.

 

SOA World Conference & Expo
SOA World Conference & Expo 2007 brings together the best minds in the business to San Francisco for a two-day conference that offers comprehensive coverage of SOA and what it means to enterprise IT today. As Zapthink analyst Jason Bloomberg has noted, "SOA involves rethinking how the business leverages IT in many various ways." Attend SOA World Conference & Expo 2007 West and learn from more than 100 speakers about how SOA is transforming business--and the way IT and business managers think about their businesses, processes, and technology.
