Performance evaluation and improvement in cloud computing environment

Cloud computing covers a wide range of applications, from online services for the end user. It becomes the new trends for most organizations to handle their business IT units. Services provided are becoming flexible because the resources and processing power available to each can be adjusted on the fly to meet changes in need [6]. However, infrastructures deployed on a cloud computing environment may induce significant performance penalties for the demanding computing workload. In our doctoral research, we aim to study, analyze, evaluate and improve performance in cloud computing environment based on different criteria. To achieve the thesis objectives, a research performed is based on a quantitative analysis of repeatable empirical experiment.
