Afinidade" entre aplicações. Para a implementação do método, foi realizado o monitoramento do consumo de recursos das máquinas virtuais para obter dados históricos de execução que permitem determinar os perfis das aplicações. Como resultado, foi criado um escalonador para alocar máquinas virtuais, cujos objetivos são evitar combinações de aplicações que causem degradação do desempenho entre si e melhorar a taxa de utilização dos recursos computacionais.
This paper presents the impact analysis of the hypervisor layer over database applications. The conclusions were reached by performing experiments with hybrid environments, composed by bare-metal servers and two types of hypervisors. The main objectives were to compare the behaviour of database applications and to determine the maximum service capacity of a virtualized database server on different environments. With the results, it was possible to assess the scalability of a database environment, according to the type of hypervisor and the number of simultaneous connections, and decide how and when to expand or reduce the virtualized infrastructure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
