Desenvolvimento e avaliação de algoritmos de otimização para o cumprimento de acordos de níveis de serviços em nuvem

Abstract

Currently the access to a cloud computing environment is provided on demand, which allows providers to offer elasticity services to customers. Although the cloud allows an abstraction of the infrastructure behavior of the service providers (logical and physical), the fulfillment of the Service Level Agreements (SLAs) is challenging, because according with the demand and system configuration, the providers cannot ensure the customers requirements. There is a necessity of mechanisms that consider load balancing algorithms to provide an efficient load distribution in the available resources. However, the papers available in the literature do not efficiently address the problem of resource equation considering the customers requirements, because they consider a limited set of objectives to be analysed and fulfilled. Therefore, this master project aims to develop and evaluate algorithms available in the literature that address the combinatorial optimization and the multi-objective approach to handle the computational resources during the execution time, trying to optimize the efficient use of the resources available in the infrastructure and fulfill the service level agreements defined between the clients and providers.
