Prediction of Performance Degradation in Cloud Computing

Cloud computing is emerged as important paradigm in information and communication technology by enabling cost effective, on demand provisioning of elastic computing resources. Because of no upfront investment, lot of organizations gets attracted towards cloud for outsourcing computational needs. But QoS assurance is one of big issue which resists organizations to go for cloud resources. To tackle with this issue, Service Level Agreement (SLA) between cloud provider and customer is generated. Any violation of SLA would lead to loss for both customer and provider of cloud. Avoiding SLA violation becomes necessary for cloud provider which leads necessity of predicting performance degradation so that necessary action to avoid violation could be carried out. In this work we focus on techniques and algorithms for prediction of performance degradation.
