Design of an Agent Based Fault Tolerant Trust Mechanism in Cloud Computing

Abstract

With the rapid growth of IT services, Cloud Computing has bought certain serious concerns with it. Some of them can be listed as trust, security, fault free or interruption free services. The Cloud Computing demands that a trustworthy or reliable service should be availed by its potential user. However, it is always a challenge for any cloud user to look for service that is suitable as well as reliable in every aspect. Various trust issues of Cloud have been addressed by a combination of frameworks, standards and related technologies. Sometimes, consumers avoid a specific technology whenever it shows no ability to cope with their security demands. For a trustworthy discovery and delivery of cloud services, a multi-layered model i.e., Multi Agent based Trust Evaluation Model (MATEM) has been proposed. It is a multi- agent trust model that will make use of multiple agents to perform and evaluate the credibility of trust through trust evaluation system. In this thesis, several parameters have been considered such as availability, throughput, turnaround, reliability, response time and data integrity. The performance validation has proven that the calculated values of trust will be provide reliable cloud services to its users and also the proposed framework has overpowered the existing mechanisms. newline
