Security and QoS guarantee-based resource allocation within cloud computing environment

Abstract

Data and services in a Cloud Computing are not limited to a single organization's perimeter and span multiple trusted or untrusted domains. In addition, data security and privacy are the most challenging barriers to generalized cloud adoption. In this paper, we propose two architectures (inter-cloud Broker and Federation) enabling best cloud resources selection based on optimal cost, Quality of Service (QoS) and security guarantee for Network as a Service (NaaS) and Infrastructure as a Service (IaaS) services in a Cloud Computing environment. We simulate our proposed framework to evaluate the best cloud resources selection and the impact of security on QoS guarantee. The obtained results show this impact and that the Broker architecture is the most economical while ensuring QoS and security requirements.
