Trechos de modelo do Amazon Redshift

O Amazon Redshift é um serviço de data warehouse totalmente gerenciado e em escala de petabytes na nuvem do . Você pode usar o AWS CloudFormation para provisionar e gerenciar clusters do Amazon Redshift.

Cluster do Amazon Redshift

O modelo de amostra a seguir cria um cluster do Amazon Redshift de acordo com os valores de parâmetro que são especificadas quando a pilha é criada. O parameter group de cluster associado ao cluster do Amazon Redshift permite o registro de atividades do usuário. O modelo também executa o cluster do Amazon Redshift em uma Amazon VPC, que é definida no modelo. A VPC inclui um gateway de Internet que permite acessar os clusters do Amazon Redshift da Internet. No entanto, a comunicação entre o cluster e o gateway de Internet também deve ser ativada, o que é feito pela entrada na tabela de roteamento.

nota

O modelo inclui a condição IsMultiNodeCluster para que o parâmetro NumberOfNodes seja declarado somente quando o valor do parâmetro ClusterType estiver definido como multi-node.

O exemplo define os parâmetros MysqlRootPassword com a propriedade NoEcho definida como true. Se você definir o atributo NoEcho como true, o CloudFormation retornará o valor do parâmetro mascarado como asteriscos (*****) para qualquer chamada que descreva a pilha ou os eventos de pilha, exceto informações armazenadas nos locais especificados abaixo.

Importante

O uso do atributo NoEcho não mascara informações armazenadas no seguinte:

  • A seção de modelo de Metadata. O CloudFormation não transforma, modifica nem edita nenhuma informação incluída na seção Metadata. Para ter mais informações, consulte Metadados.

  • A seção de modelo de Outputs. Para ter mais informações, consulte Outputs.

  • O atributo Metadata de uma definição de recurso. Para ter mais informações, consulte Atributo Metadata.

É altamente recomendável não usar esses mecanismos para incluir informações confidenciais, como senhas ou segredos.

Importante

Em vez de incorporar informações confidenciais diretamente em modelos do CloudFormation, recomendamos usar os parâmetros dinâmicos no modelo da pilha para fazer referência a informações confidenciais que são armazenadas e gerenciadas de forma externa ao CloudFormation, como no AWS Systems Manager Parameter Store ou no AWS Secrets Manager.

Para obter mais informações, consulte as práticas recomendadas do Não incorporar credenciais em seus modelos.
