Global Trust: A Trust Model for Cloud Service Selection

By Fatima Zohra Filali Belabbes Yagoubi

DOI:, Pub. Date: 8 Apr. 2015

Cloud Computing refers to network-based service provided by a large number of computers, sharing computing and storage resources. Combined with on-demand provisioning mechanisms and relied on a pay-per-use business model.
The Cloud Computing offers the possibilities to scale rapidly, to store data remotely and to share services in a dynamic environment. However, these benefits can be seen as weaknesses for assuring trust, and providing confidence to the users of service. In this case, some traditional mechanisms to guarantee reliable services are no longer suitable or dynamic enough, and new models need to be developed to fit this paradigm.
This study describes the assessment of the trust in the context of Cloud Computing, proposes a new trust model adapted to Cloud environments, and shows some experiments in regards of the proposed solution.
