Project Summary

Project Title: A Multi-Tenancy Cloud Trust Model Using Quality of Service Monitoring: A Case of Infrastructure as a Service (IaaS)

Research Supervisor: Dr. Andrew Mwaura Kahonge

Abstract: Digitization and changes in technological trends have necessitated the need for enterprises to start or have plans to migrate their services to cloud computing environments. Thereby, benefiting from the many advantages that come with cloud computing. When a service level agreement is made between a cloud consumer and the cloud provider, the consumer usually is left with no choice but to trust the provider will deliver their bit. They have faith but lack a way of verifying or even doing QoS monitoring on their own. To solve this problem, we propose a multi-tenancy cloud trust model that uses QoS monitoring. It focuses on Infrastructure as a Service and, as seen in the results, assists cloud consumers evaluate cloud service providers well before they purchase services. This prevents them from leasing already congested clouds, or which do not meet their specifications. Cloud providers also stand to gain. A provider that honors their SLAs will tend to be more trusted than one who does not, leading to better reputation.
