Arquiteturas de servidor único e múltiplas arquiteturas de servidor virtual: Análise de desempenho no Proxmox VE para sistemas de e-learning
Resumo
Neste momento, quase todas as instituições de ensino utilizam o sistema de e-learning para apoiar a aprendizagem. O fator que desempenha maior papel no uso confortável de um sistema é o aspecto do desempenho. Este tipo de arquitetura de servidor único é muito comumente aplicado na construção de um sistema, mas na verdade é menos eficiente porque não presta atenção ao nível de disponibilidade. Neste estudo, uma arquitetura de servidor foi construída na forma de múltiplos servidores virtuais utilizando virtualização em Proxmox, aplicando técnicas de proxy reverso e clustering de armazenamento para aumentar a disponibilidade do sistema na construção de um sistema Moodle de e-learning. O projeto de múltiplas arquiteturas de servidores virtuais utiliza metodologias de preparação, planejamento, projeto, implementação, teste e otimização. Os resultados da pesquisa no ambiente de teste e no plano de teste mostram que a arquitetura de múltiplos servidores virtuais tem disponibilidade superior em comparação com a arquitetura de servidor único. Com base nos resultados do teste User Behavior Modeling Performance (UBMP), a arquitetura de múltiplos servidores virtuais também é superior, com um valor máximo de 100 usuários simultâneos na arquitetura de múltiplos servidores virtuais, onde o nível de disponibilidade é de 80,25%, enquanto no servidor único, é inferior com um valor de 80 utilizadores e um nível de disponibilidade de 78,4%.
