摘要：IaaS model in the Cloud Computing provides infrastructure services to users. However, the provider of such centralized Cloud requires notable investments to maintain the infrastructures. P2P Cloud, whose infrastructures are provided by multiple volunteer nodes in the P2P network, gives a low cost option to the provision of Cloud Computing. P2PCloud workflow is used to handle tasks with control and data dependencies, and plays an important role in P2PCloud environment. It is essential to design an appropriate model to satisfy the distributed and heterogeneous workflow systems that must be flexible, reusable, dynamic feature in higher level. In this paper, An architecture of a P2PCloud system firstly is proposed, and then a P2PCloud-W(P2PCloud workflow system) framework is proposed, which is a novel hybrid decentralized workflow management system facilitating both Cloud and P2P technologies. Finally, a P2PCloud-W case is analyzed using Petri Net.
