A single instantiation of an atomic or composite service running in an execution zone and identified by a service identifier. There will usually be multiple instances of the same service running in the same execution zone and across many execution zones, all identified by the same service identifier.

Abstract
This chapter introduces a new paradigm for service centric networking. Building upon recent proposals in the area of information centric networking, a similar treatment of services – where networked software functions, rather than content, are dynamically deployed, replicated and invoked – is discussed. Service-centric networking provides the mechanisms required to deploy replicated service instances across highly distributed networked cloud infrastructures and to route client requests to the closest instance while providing more efficient network infrastructure usage, improved QoS and new business opportunities for application and service providers.
