Abstract

Cloud computing provides a large pool of accessible resources (hardware, platform, software) in a form of services. It became a cost effective alternative to the traditional IT infrastructure. Nowadays, as more and more e-commerce companies delegate their task to cloud providers, Services Level Agreement (SLA) became an important aspect between the cloud consumer and cloud provider, the dynamic nature of cloud computing needs to continue monitoring of the services. The restricted choice of appropriate parameters in SLA affects the interacting of end user with cloud services and creates risks of user data. End users are concerned about their data and how it will be stored in cloud and how the data is recovered in the case of failure of disaster. However, none of SLAs consider the end user view while conducting the SLA document. In this paper, we reviewed the existing SLA framework in cloud computing and introduced SLA framework for e-commerce cloud based on WSLA lifecycle. In this paper, a list most appropriate parameters and objectives which should be included in the SLA are provided to alleviate the risks facing the e-commerce cloud end user. The proposed framework may provide holistic guarantee for the end user to interact with ecommerce cloud websites.
