Como continuidade deste trabalho de mestrado, propomos quatro sugestões de trabalhos futuros. As propostas são descritas a seguir.
• Implementação de uma fórmula mais abrangente para estimativas de custos, consi- derando outros aspectos como por exemplo, horas trabalhadas;
• Embora os modelos concebidos auxilie os gestores na análise de métricas relaciona- das a vazão de análise, custo e disponibilidade, pode-se gerar novos modelos SPNs para avaliação de performabilidade do CAC que contemplem outras métricas de desempenho e dependabilidade, como por exemplo, utilização e indisponibilidade do serviço;
• De forma a garantir os níveis de serviços (SLAs) na adoção de uma infraestrutura em nuvem, é proposta uma adaptação no modelo de Performabilidade com Cloud que considere um limite de contribuintes em atendimento;
• Desenvolvimento de uma ferramenta que traduza automaticamente processos de negócio construídos na notação BPMN para modelos SPNs e que possibilite análise qualitativa dos modelos incluindo técnicas de análise de invariantes, bem como, possibilitar estimar de forma direta métricas de custo, vazão e disponibilidade.
