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...
Grid applications composed of multiple, distributed jobs are common areas for applying Web-scale workflows. Workflows over grid infrastructures are inherently complicated due to the need to both functionally assure the entire process and coordinate the underlying tasks. Often, these applications are long-running, and fault tolerance becomes a significant concern. Transparency is a vital aspect to...
The execution of job flow applications is a reality today in academic and industrial domains. In this paper, we propose an approach to adding self-healing behavior to the execution of job flows without the need to modify the job flow engines or redevelop the job flows themselves. We show the feasibility of our non-intrusive approach to self-healing by inserting a generic proxy to an existing two-level...
