Avaliação Resiliente de Autorização UCONABC para Computação em Nuvem
Abstract
The cloud services contractor needs a fine grained control of each user's individual consumption to define usage management procedures with higher precision. A UCONABC approach offers individualized periodic evaluations, performing continuous reevaluations of a user's authorization attributes. However, this approach was not designed for the dynamic context of cloud computing. The work presented in this paper shows that it is possible to provide resilience to the process of reevaluating authorizations of UCONABC. The development of proof of concept shows cloud computing provides elasticity to the entities responsible for attribute accounting and its evaluation, enabling the proposed approach.
