Customized SLAs In Cloud environments

Abstract

Nowadays, the demand for online storage is increasing. Customers store their data and can retrieve them anytime and from anywhere without having to care about back up and data recovery. SLAs between Cloud providers and customers determine the level of service guaranteed by the former. A customer can be anyone from an individual person to enterprises. Customers have different needs and preferences. Our proposed system permits the creation and enforcement of customized SLAs, where customers choose the requirements that they need fulfilled. The proposed SLAs are associated with content terms pertaining to the nature of the content of the data stored. SLA enforcement is based on rules that are updated in runtime in order to proactively detect possible SLA violations and handle them in an appropriate manner. © 2013 IEEE.
