What is Service Oriented Architectures (SOA)

The authors use P2P communications for building a powerful service oriented architecture capable of orchestrating advanced services. Underlying mechanisms can be supported even when subject to the high churn of some of the P2P elements. This work proposes a management framework that ties together P2P and SOC technologies to reach new work scenarios for the future Internet. P2P nodes dynamically form networks to emulate the services offered by a traditional “dedicated” server. Such behavior of P2P-based services is highly dynamic and requires the use of a real-time control plane such as the one proposed in this chapter. The authors therefore argue that a policy based management middleware offers a good alternative for such endeavor. They recommend that emerging SOC/SOA development should consider the addition of a special intermediary component that transparently deals with highly dynamic P2P nodes and services as they expect these to become the rule rather than the exception in certain scenarios. Although not all the issues have been dealt with here in this chapter, it can certainly be seen as a step in the right direction.
