Monitoring Decentralized Interacting Services with a Global State Choreography Model

Abstract

This paper presents an approach to the runtime management of decentralized service compositions. The goal of the approach is to transparently observe the behavior of peer-to-peer service interaction in order to permit the introduction of adaptive behavior. The design includes a monitoring component that utilizes a choreography model to formulate a global view of the application, and introduce adaptive behavior in a unique way. The design incorporates a mechanism for transforming the choreography to introduce redundancy, and dynamic selection in the interaction.
