Cloud SQL 인스턴스에 연결하려면 먼저 Cloud SQL 인스턴스와 지원 네트워킹 리소스를 배포하고 구성하는 방법을 결정해야 합니다. Cloud SQL 인스턴스가 이미 구성되고 배포된 경우 이 페이지를 통해 클라이언트를 기존 인스턴스에 연결하는 다양한 방법을 알아볼 수 있습니다.
IP 주소 유형: 비공개 또는 공개
Cloud SQL 인스턴스를 처음 만들 때 공개 IP 주소, 비공개 IP 주소 또는 두 가지 모두로 인스턴스를 구성할지 선택할 수 있습니다.
애플리케이션 요구사항에 따라 인스턴스의 IP 주소 구성을 선택합니다. 그런 다음 인스턴스를 구성한 후 클라이언트 연결 문자열에 공개 IP 주소, 비공개 IP 주소 또는 경우에 따라 DNS 이름을 지정합니다.
비공개 IP 주소
공개 IP 주소
설명
내부, 가상 프라이빗 클라우드(VPC) 네트워크 전용(비공개) IP 주소
인터넷 액세스가 가능한(공개) 외부 IP 주소
결정 지점
Google Cloud 내부의 VPC 네트워크에 호스팅된 클라이언트 또는 이러한 VPC 네트워크에 액세스할 수 있는 클라이언트에서 연결해야 하나요?
그렇다면 인스턴스에 비공개 IP 주소를 선택합니다.
Google CloudVPC 네트워크 외부의 클라이언트에서 공용 인터넷을 통해 연결해야 하나요?
그렇다면 인스턴스에 공개 IP 주소를 선택합니다.
구성 옵션
다음 유형의 비공개 네트워킹 구성이 지원됩니다.
비공개 서비스 액세스: 네트워킹 피어링을 기반으로 단일 VPC 네트워크에서 Cloud SQL 인스턴스에 연결합니다.

If your Cloud SQL instance is\nalready configured and deployed, then this page can help you understand\nthe different ways that you can connect your clients to the\nexisting instance.\n\nIP address type: private or public\n----------------------------------\n\nWhen you first create your Cloud SQL instance,\nyou can choose whether to configure the instance with a *public IP address* ,\na *private IP address* , or a *combination of both*.\n\nYou choose the IP address configuration of your instance based on your\napplication requirements. Then after you configure your instance, you\nspecify either a public IP address, a private IP address, or in some cases a\nDNS name in your client connection string.\n\nConnection type: Cloud SQL connector or direct\n----------------------------------------------\n\nWhen you make the connection to a Cloud SQL instance, you can use a\nCloud SQL connector, or you can make a direct connection.\n\nA Cloud SQL connector is either the [Cloud SQL Auth Proxy](/sql/docs/sqlserver/sql-proxy) or\none of the [Cloud SQL Language Connectors](/sql/docs/sqlserver/language-connectors).\n\nDatabase authentication type: Managed Service for Microsoft Active Directory or built-in\n----------------------------------------------------------------------------------------\n\nWhen you connect to an instance, you must authenticate as a database user.\nYou can choose between [built-in authentication in Cloud SQL for SQL Server](/sql/docs/sqlserver/users) or\n[Managed Microsoft AD](/sql/docs/sqlserver/ad).\n\nPrivate networking options when using a private IP address\n----------------------------------------------------------\n\nWhen you configure your instance to use a private IP address, you can choose\nthe following private networking options: private services access,\nPrivate Service Connect, or both.\n\n### Supported features\n\nThe following table lists the features that Cloud SQL supports when\nyou connect to an instance that's configured with one or both of the private\nnetworking options.\n\n### Remove networking options from an instance\n\nCloud SQL supports the removal of the following networking options\nfrom an instance:\n\n- Public IP from an instance with both private services access and public IP\n- Public IP from an instance with public IP, private services access, and Private Service Connect\n- Private Service Connect from an instance with both Private Service Connect and private services access\n- Private Service Connect from an instance with Private Service Connect, private services access, and public IP\n\n### Enable networking options for an instance\n\nYou can enable Cloud SQL supports enabling the following connection options for instances:\n\n- Private services access on an instance with public IP only\n- Private Service Connect on an instance with private services access only\n- Private Service Connect on an instance with both private services access and public IP\n- Public IP on an instance with private services access only\n\n### Limitations\n\n- You can't create an instance with both a public IP address and Private Service Connect.\n- You can't remove private services access from an instance with private services access and Private Service Connect.\n- You can't remove private services access from an instance with private services access and public IP.\n- If you have an instance that uses only public IP, then you can't enable both private services access and Private Service Connect at the same time. First, enable private services access, and then enable Private Service Connect.\n- You can't use authorized networks to do IP address-based allowlisting for Private Service Connect instances.\n\nTools for connecting to Cloud SQL\n---------------------------------\n\nThe following table contains some options for connecting to Cloud SQL:\n\nTroubleshoot\n------------\n\nIf you're having problems connecting, then check the following pages for help\ndebugging or finding solutions to known issues:\n\n- [Debugging connection issues](/sql/docs/sqlserver/debugging-connectivity)\n- [Known connectivity errors](/sql/docs/sqlserver/troubleshooting#connectivity)\n- [Troubleshooting Cloud SQL Auth Proxy connection](/sql/docs/sqlserver/connect-auth-proxy#troubleshooting)\n- [Common connection issues](/sql/docs/sqlserver/diagnose-issues#connection)\n\nWhat's next\n-----------\n\n- Learn how to connect with the [Quickstart for Cloud SQL for sqlserver](/sql/docs/sqlserver/quickstart).\n- Learn best practices for [managing database connections](/sql/docs/mysql/manage-connections).\n- Learn about [IAM database authentication](/docs/authentication).\n- Learn about [connecting using a sqlcmd client from a local machine or Compute Engine](/sql/docs/sqlserver/connect-admin-ip).\n- Learn about [configuring IP connectivity](/sql/docs/sqlserver/configure-ip).\n- Learn about [the Cloud SQL Auth Proxy](/sql/docs/sqlserver/sql-proxy).\n- Learn about [options for support](/sql/docs/sqlserver/support)."]]
