A Service Level Agreement for the Resource Transaction Risk Based on Cloud Bank Model

Cloud computing is a new business computing model. The environment of the resources is very complex. The resources are physically distributed and connected by the network. There are many risks existing in the resource transactions. So how to make sure that the cloud computing platform can avoid these risks during the transactions and assure the quality of services (QoS) provided to the consumers is a very important issue in cloud computing. Service Level Agreement (SLA) is proposed to solve the problems between the customers and service suppliers. Cloud Bank model [1] is a resource management model based on economic principles and aims at solving all the commercial level problems in cloud computing. This paper presents a framework of Service Level Agreement based on the Cloud Bank's liquidity risk [2] predicting model. This SLA can help the Cloud Bank avoid the risks and assure the QoS to the consumers.
