Cloud computing is emerging in the form of an outsourcing model which promises to provide a reliable service to the consumers. With the introduction of numerous cloud service providers around the globe, that store sensitive information at unknown locations, the issues regarding security of data and building trust between the provider and consumer are growing. The Service Level Agreement (SLA) is becoming a very effective tool in gaining consumer’s trust and helps consumers to measure service provider’s performance with respect to various attributes of services in concern. This paper presents a review on the attributes of the SLA and their significance in adopting the cloud computing services. An effort is also being made towards standardization of the SLA for cloud computing services that in turn may help adopting cloud computing services on a larger scale.
