Cooperative agents-based decentralized framework for cloud services orchestration

The Software as a Service provides complete software systems. SaaS is known as "on-demand software". In the Cloud Computing, Business Process Execution Language (BPEL) is widely used in SaaS application development. BPEL is the de facto standard for business process modeling in today´s enterprises and is a promising candidate for the integration of business. It allows describing the control flow needed to orchestrate a set of services into a meaningful business process. However, current BPEL implementations do not provide an orchestration framework that take into account the quality of service (QoS) of Clouds and services in addition to the deployment of a centralized framework. In this paper, we propose a decentralized approach to the orchestration of Cloud services using multi-agent system (MAS). The proposed framework orchestrates dynamically concrete services by delegating an agent to each <;invoke> activity of a BPEL process.
