Cloud SQL 고가용성 사용 설정 추천자는 데이터 중복을 제공하여 SLA 내에서 중요한 인스턴스를 가져오는 데 도움이 될 추천을 사전에 생성합니다. 영역 서비스 중단 발생 시 또는 인스턴스에 메모리가 부족할 때 유용할 수 있습니다.
이 페이지에서는 Cloud SQL 고가용성 사용 설정 추천자, 이 추천자의 작동 방식, 사용 방법을 설명합니다.
작동 원리
Cloud SQL 고가용성 사용 설정 추천자는 인스턴스 메타데이터를 분석합니다. 인스턴스가 중요 워크로드를 지원하는 인스턴스와 유사하게 구성되었지만 고가용성이 사용 설정되지 않은 경우 Cloud SQL에서는 99.95% 가용성 SLA가 적용되는 고가용성을 사용 설정하거나 99.99% 가용성 SLA가 적용되는 고가용성을 갖춘 Cloud SQL Enterprise Plus 버전으로 마이그레이션하도록 추천합니다.
가격 책정
Cloud SQL 고가용성 사용 설정 추천자는 모든 Google Cloud 고객에게 무료로 제공됩니다.

권장사항
이 인스턴스는 중요한 워크로드를 지원하는 인스턴스와 유사하게 구성되어 있지만 가용성이 높지 않습니다. 단일 영역 인스턴스는 다운타임에 더 취약합니다.
하위 유형: CRITICAL_INSTANCE_HIGH_AVAILABILITY_NOT_ENABLED
99.95% 가용성 SLA가 적용되는 고가용성을 사용 설정하거나, 또는 더 높은 99.99% 가용성 SLA가 적용되는 고가용성을 갖춘 Cloud SQL Enterprise Plus 버전으로 마이그레이션하세요. 고가용성을 사용 설정하면 인스턴스를 멀티 영역으로 만들어 한 리전 내에서 데이터를 복제하여 영역별 서비스 중단으로부터 보호하고 다운타임을 제한하며 복구 시간을 개선할 수 있습니다.

This might\nbe helpful during a zonal outage or when an instance runs out of memory.\n\nThis page describes the Cloud SQL enable-high-availability recommender, how this\nrecommender works, and how to use it.\n\nHow it works\n------------\n\nThe Cloud SQL enable-high-availability recommender analyzes the instance metadata. If the instance\nis configured similar to instances that support important workloads but doesn't\nhave high availability enabled, then Cloud SQL recommends that you enable high\navailability for 99.95% availability SLA, or migrate to Cloud SQL Enterprise Plus edition with high\navailability for 99.99% availability SLA.\n| **Note:** Recommendations are generated daily.\n\nPricing\n-------\n\nThe Cloud SQL enable-high-availability recommender\nis available free of cost to all Google Cloud customers.\nFor more information, see [Recommender pricing](/recommender/pricing).\n\nBefore you begin\n----------------\n\nBefore you can view recommendations and insights, do the following:\n\n- To get the permissions to view and work with insights and recommendations, ensure that you have the required [Identity and Access Management (IAM) roles](/sql/docs/mysql/project-access-control#roles).\n\n For more information about IAM roles, see [IAM basic and predefined roles reference](/iam/docs/understanding-roles) and [Manage access to projects, folders, and organizations](/iam/docs/granting-changing-revoking-access).\n-\n\n\n Enable the Recommender API.\n\n\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=recommender.googleapis.com)\n\nList enable-high-availability recommendations\n---------------------------------------------\n\n### Console\n\nTo list enable-high-availability recommendations by using the\nGoogle Cloud console, follow these steps:\n\n1.

For more information, see\n [Enable and disable high availability](/sql/docs/mysql/configure-ha#console_1).\n\n | **Caution:** Once you start the high availability configuration on an instance, you can't stop it. This operation restarts the instance and can lead to an increase in cost and a brief downtime. It typically takes only a few minutes for the configuration and the restart operation to complete. However, if the instance has a large disk or load, then it might take up to an hour.\n - Migrate to the Cloud SQL Enterprise Plus edition.
