Parameters for Service Level Agreements Generation in Cloud Computing - A Client-Centric Vision

Current Service Level Agreements are lacking completeness. They often leave out parameters that are important for the consumer. In addition, SLAs are predefined by the service providers and the consumer does not have a say in them. The goal of this paper is to find the important parameters that should initially be included in a Service Level Agreement between a cloud service provider and a cloud service consumer. In this paper we are showing a client-centric view of the SLA. Some examples for SLAs of services in the market are illustrated, in order to show the need to specify, which parameters should be included in the SLAs.
