Architecting and implementing secure and flexible Service Oriented Architectures (SOA) requires an ability to mediate interactions between services based on a declarative and remediable policy language. Coding interaction policies between services results in brittle SOA infrastructures that can't accommodate changing security and business needs. In this talk given by Layer 7 CTO Dr. Toufic Boubez, you will hear how a Policy control infrastructure for SOA can be used to engineer loosely-coupled SOA architectures that can span security domains.
