Customer satisfaction model in cloud computing environment

Service level agreements are widely accepted mechanism for gaining enterprise-level information technology (IT) resources. The IT infrastructure provided by the Cloud provider must meet SLA established with the customer. SLA is generally used mechanism to determine contracts accessing requirements in business content. It defines a set of non-operating requirements of the service and also, incorporates penalties for unsatisfied requirements. The numbers ofcloud customers are increasing day-by-day resulting in the increased loads on cloud service providers, thus, making Service Level Agreement (SLA) a prime need of time for ensuring the service quality. This helps in meeting the challenges presented by enterprise-oriented application software's towards traditional sales models. This paper is an attempt to devise a mathematical model for better handling of cloud's resources and increasing the satisfaction level of cloud customers by meeting SLA constraints.
