Towards Trustworthy Resource Scheduling in Clouds

Managing the allocation of cloud virtual machines at physical resources is a key requirement for the success of clouds. Current implementations of cloud schedulers do not consider the entire cloud infrastructure neither do they consider the overall user and infrastructure properties. This results in major security, privacy, and resilience concerns. In this paper, we propose a novel cloud scheduler which considers both user requirements and infrastructure properties. We focus on assuring users that their virtual resources are hosted using physical resources that match their requirements without getting users involved with understanding the details of the cloud infrastructure. As a proof-of-concept, we present our prototype which is built on OpenStack. The provided prototype implements the proposed cloud scheduler. It also provides an implementation of our previous work on cloud trust management which provides the scheduler with input about the trust status of the cloud infrastructure.
