Resource Self-management under an SLA within a Cloud Networking Environment

摘要

Today, cloud networking is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end SLA between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) in a cloud networking environment (inter-cloud Broker and Federation architecture). Then, we propose the self-management of cloud resources under the established SLA using specific autonomic cloud managers. We simulate our proposed framework to provide videoconferencing and intensive computing applications with self-management and QoS guarantee. We observe that the Broker architecture is the most economical, while ensuring QoS requirements.
