Os administradores de nuvem podem aproveitar o plug-in do Google Cloud Platform (GCP) para criar balanceadores de carga para oferecer suporte a soluções personalizadas, incluindo alta disponibilidade.
Você pode configurar vários aspectos da configuração de balanceadores de carga para oferecer suporte a requisitos específicos. Esses recursos podem oferecer suporte à infraestrutura de provisionamento para SAP NetWeaver e SAP Hana, por exemplo. Essa configuração permite implantar diferentes instâncias de balanceador de carga em zonas de disponibilidade diferentes.
- Crie uma conta de nuvem do GCP se você não tiver uma.
- Configure mapeamentos de tipo e imagem.
- Crie um perfil de rede padrão.
- Crie zonas de disponibilidade de processamento e marque-as apropriadamente. Essas tags permitem provisionar instâncias e grupos de instâncias para zonas de disponibilidade específicas em um modelo.
- O modelo deve modelar a configuração apropriada do balanceador de carga com especificações para verificações de integridade, instâncias do, grupos de instâncias, serviços de back-end, regras de encaminhamento e firewalls.
- O modelo deve especificar as máquinas virtuais e as zonas de disponibilidade nas quais elas devem ser implantadas.
Configurando um balanceador de carga TCP interno
Este modelo de exemplo usa auxiliares de alocação para fornecer lógica de alocação para vários recursos. O modelo contém duas instâncias do, grupos de instâncias, um recurso de verificação de integridade, um recurso de firewall, um recurso de serviço de back-end e um recurso de regra de encaminhamento.
Depois de implantar esse modelo, você poderá fazer login no Google Cloud Console para filtrar e escolher as instâncias do que deseja adicionar ao seu grupo de instâncias. Somente instâncias na mesma zona que o grupo de instâncias serão mostradas como opções. Consulte Grupos de instância no console do Google Cloud.
