Cloud federation is an architecture that allows cloud providers to make use of their unallocated virtual machines, by combining their resources to serve a pool of cloud consumers whose requests cannot be handled by any of these providers alone. A client is willing to rent computing resources from the cloud providers or federations due to the advantages they can provide. The quality of service (QoS) is one of the main factors that attracts or discourages the clients from renting such services. What complicates the process is having the actual QoS delivered being worse than the promised QoS. Such could lead to the client changing federation, and the latter getting dissociated. Some of the main reasons that could result in worsening the QoS are encountering passive malicious cloud providers after the federation formation, and having unstable federation formation. In this thesis, we present solutions for such problems in order to increase the lifespan of the formed federations, by introducing a maximin game to prevent the malicious providers from accomplishing their wicked schemes without getting penalized, and advancing a genetic and an evolutionary game theoretical models for the federation formation process to bypass the dynamicity boundaries. Experiments conducted using CloudHarmony real-world dataset revealed that both of our solutions were able to increase the total profit obtained by the federations and ameliorate the QoS delivered, granting the cloud consumer a great experience with the service.

Global Coordination

Cloud Computing has become the popular paradigm for accessing the various scalable and on-demand computing services over the internet. Nowadays, individual Cloud Service Providers (CSPs) offering specialized services to the customers collaborate to form the Cloud Federation, in order to reap the real benefits of Cloud Computing. By collaboration, the member CSPs of the federation achieve better resource utilization and Quality of Service (QoS), thereby increasing their business prospects. When a CSP runs out of resources in the Cloud Federation, in order to offload the customer requests for resources to other CSP(s), identifying a suitable partner is a challenging task due to the lack of global coordination among them. In this paper, we propose the design and implementation of an efficient partner selection mechanism in the Cloud Federation, using the Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods, and also considering the trust values of various CSPs in the federation. The AHP method is used to calculate the weights of the QoS parameters used in the TOPSIS method which is used to rank the various CSPs in the Cloud Federation according to the user requirements. Simulation results show the effectiveness of this approach in order to efficiently select the trustworthy partners in large scale federations to ensure the required QoS to the cloud consumers.
