<a name="quickref-redshift"></a>

Amazon Redshift는 클라우드에서 완전히 관리되는 페타바이트급 데이터 웨어하우스 서비스입니다. CloudFormation을 사용하여 Amazon Redshift 클러스터를 프로비저닝하고 관리할 수 있습니다.

## Amazon Redshift 클러스터
<a name="quickref-redshift-samplecluster"></a>

다음 샘플 템플릿은 스택 생성 시 지정된 파라미터 값에 따라 Amazon Redshift 클러스터를 생성합니다. Amazon Redshift 클러스터와 연결된 클러스터 파라미터 그룹은 사용자 활동 로깅을 가능하게 합니다. 또한 이 템플릿은 템플릿에 정의된 Amazon VPC에서 Amazon Redshift 클러스터를 시작합니다. VPC에는 인터넷 게이트웨이가 포함되어 있어 인터넷에서 Amazon Redshift 클러스터에 액세스할 수 있습니다. 그러나 클러스터와 인터넷 게이트웨이 간에 통신이 활성화되어 있어야 하며, 통신은 라우팅 테이블 항목을 통해 활성화합니다.

**참고**  
템플릿에는 `IsMultiNodeCluster` 파라미터 값이 `NumberOfNodes`로 설정된 경우에만 `ClusterType` 파라미터가 선언되는 `multi-node` 조건이 포함되어 있습니다.

이 예에서는 `MysqlRootPassword` 속성이 `NoEcho`로 설정된 `true` 파라미터를 정의합니다. `NoEcho` 속성을 `true`로 설정한 경우, 아래 지정된 위치에 저장된 정보를 제외하고 CloudFormation은 스택 또는 스택 이벤트를 설명하는 모든 호출에 대해 별표(\$1\$1\$1\$1\$1)로 마스킹 처리된 파라미터 값을 반환합니다.

**중요**  
`NoEcho` 속성을 사용해도 다음에 저장된 정보는 마스킹되지 않습니다.  
`Metadata` 템플릿 섹션. CloudFormation은 `Metadata` 섹션에 포함된 정보를 변환, 수정 또는 삭제하지 않습니다. 자세한 내용은 [메타데이터](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html)를 참조하십시오.
`Outputs` 템플릿 섹션. 자세한 내용은 [출력](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/outputs-section-structure.html)을 참조하십시오.
리소스 정의의 `Metadata` 속성입니다. 자세한 내용은 [`Metadata` 속성](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-attribute-metadata.html)을 참조하세요.
이러한 메커니즘을 사용하여 암호나 보안 정보와 같은 중요한 정보를 포함하지 않는 것이 좋습니다.

**중요**  
AWS Systems Manager Parameter Store 또는 AWS Secrets Manager와 같이 CloudFormation 외부에서 저장 및 관리되는 중요한 정보를 참조하려면 CloudFormation 템플릿에 직접 중요한 정보를 포함하는 대신 스택 템플릿에 있는 동적 파라미터를 사용하는 것이 좋습니다.  
자세한 내용은 [템플릿에 자격 증명을 포함하지 않음](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/security-best-practices.html#creds)을 참조하십시오.
