Requisitos não Funcionais e Sustentabilidade para Computação em Nuvem: uma Revisão Sistemática da Literatura

Abstract

Resumo A computação em nuvem continua a se disseminar no mundo web, possibilitando o uso de aplicações, plataformas e infraestruturas através de conexões remotas. Requisitos não funcionais de grande importância para computação em nuvem devem considerar desempenho e sustentabilidade, de modo a impactar diretamente nos custos e na qualidade dos serviços prestados, considerando ainda evitar (maiores) danos à saúde ambiental. Uma das grandes dificuldades enfrentadas é a falta de padrões na adoção desta tecnologia, o que implica na maneira de melhor configurar infraestruturas, levando em conta a diversidade de requisitos essenciais que devem ser atendidos para garantias de entrega e fornecimento dos serviços. Este trabalho apresenta quais requisitos não funcionais e parâmetros de sustentabilidade necessitam de especial atenção no processo de migração para computação em nuvem. Os dados são apresentados como resultados de uma revisão sistemática da literatura.

Challenges, Patterns and Sustainability Indicators for Cloud Computing

“…A systematic literature review is a means of identifying, evaluating, and interpreting available relevant research to an area topic or phenomenon of interest, whether to synthesize evidence on a given area or to identify gaps for further investigation [Kitchenham 2004]. In this work, we follow the phases of a systematic review following the process of conducting by the proposed recommendations [Kitchenham 2004] and present new results for the LSR shown in [Camboim and Alencar 2018].…”

“…The main objective of the systematic review presented in [Camboim and Alencar 2018] was to identify whether there is standardization to support the migration to cloud computing in private infrastructure, considering non-functional requirements that support sustainability. For this investigation, the authors defined the following research questions:…”

“…Table 1 shows what these aspects are and shows how many studies refer to them. Source [Camboim and Alencar 2018] From the data presented, it was clear to define that for all articles that address sustainability, the pillar specifically considered was the environmental one. However, it is still necessary to analyze how these aspects influence the social and economic pillars, given that when energy efficiency is achieved, in a certain way and in the long run, there is an impact on cost reduction because the three are intrinsically related.…”

“…However, it is still necessary to analyze how these aspects influence the social and economic pillars, given that when energy efficiency is achieved, in a certain way and in the long run, there is an impact on cost reduction because the three are intrinsically related. Also, according to the authors [Camboim and Alencar 2018], 21 articles somehow addressed possible gaps that can be better investigated which may arise as an open problem for cloud computing. Regarding sustainability, the most cited problems were:…”
