A Multi-tenancy Cloud Trust Model Using Quality of Service Monitoring- a Case of Infrastructure as a Service (Iaas)

Abstract

Digitization and changes in technological trends have necessitated the need for enterprises to start or have plans of migrating their services to cloud computing environments. This is to benefit from the many advantages that come with cloud computing. Third party providers whom majorly consume multi-tenancy architectures mainly offer the cloud platforms. This come with some challenges mostly when it comes to trust. The cloud consumers and cloud providers agree on some cloud service level agreements. Mostly the consumers have faith that they benefit from what they have agreed with the provider but lack a way of verifying the SLAs as well as doing QoS monitoring on their own. This research project focuses on coming up with a multi-tenancy cloud trust model using QoS monitoring. Our key focus was the infrastructure as a service cloud model. It also involved developing a prototype to show case the proposed model. The overall research strategy employed was exploratory. The model developed assists cloud consumers to be able to evaluate cloud services before they purchase services. This prevents them from leasing already congested clouds, or which do not meet their specifications. They also have the capability of continuous QoS monitoring of the cloud environment in real time when need be. On the other hand, cloud providers also benefit from the trust provided by our model because it might lead to good company reputation making them to sell more.
