이 문서에서는 Private Service Connect(PSC)를 사용하여 클라이언트에서 Apigee로의 라우팅(일명 '상위' 트래픽)을 구성하는 방법을 설명합니다.
개요
PSC를 사용하여 Apigee VPC를 Apigee와 피어링한 VPC 또는 사용자가 제어하는 다른 VPC와 연결할 수 있습니다. 이 아키텍처 패턴을 사용하면 전역 부하 분산기에서 Apigee로 요청을 전달하기 위해 관리형 인스턴스 그룹(MIG)을 만들 필요가 없습니다. PSC 라우팅 방법을 사용하면 API 프록시 요청이 VPC에 설치하는 전역 외부 HTTP(S) 부하 분산기를 통해 Apigee VPC의 단일 연결 지점(서비스 연결이라고 함)으로 전달됩니다.
이 구성을 사용하면 네트워크가 사용 설정된 모든 머신에서 Apigee API 프록시 요청을 보낼 수 있습니다. 그림 1을 참조하세요.
다음과 같은 지원되는 상위 PSC 기능을 참조하세요.
기존 Apigee 인스턴스에서 PSC를 사용할 수 있습니다.
Envoy 기반 Google Cloud 전역 외부 HTTP(S) 부하 분산기에 여러 PSC 네트워크 엔드포인트 그룹(NEG)을 연결할 수 있습니다.
2024년 10월 10일에 Apigee 인스턴스에 대해 프로젝트별로 허용되는 PSC NEG 연결에 대한 제한이 20에서 100개로 증가했습니다. 이 날짜 이후에 생성되는 모든 Apigee 인스턴스에 대해서는 이 섹션의 단계에 따라 새로운 한도가 적용되도록 소비자 허용 목록을 업데이트해야 합니다. 새로운 연결 한도를 적용하려면 각 Apigee 인스턴스를 한 번만 업그레이드하면 됩니다. 또한 Private Service Connect(PSC) 한도를 참조하세요.
Apigee 인스턴스에 연결된 모든 Cloud 프로젝트에서 총 1,000개가 넘는 PSC NEG 연결이 필요한 경우 Google Cloud 지원팀에 문의하세요.
더 높은 연결 한도를 활용하도록 Apigee 인스턴스의 소비자 허용 목록을 업데이트하려면 다음 단계를 수행합니다.

This architectural pattern\neliminates the need to create managed instance groups (MIGs) to forward requests from the global\nload balancer to Apigee. With the PSC routing method, API proxy requests pass through\na [global external HTTP(S) load balancer](https://cloud.google.com/load-balancing/docs/https) that you install in a VPC to a single\npoint of attachment in the Apigee VPC, called a [Service Attachment](https://cloud.google.com/vpc/docs/private-service-connect#service-attachments).\nThis configuration lets you send\nApigee API proxy requests from any\nnetwork-enabled machine. See Figure 1.\n\n\nNote the following supported northbound PSC features:\n\n- You can use PSC with any existing Apigee instance.\n- You can attach multiple PSC network endpoint groups (NEGs) to the Envoy-based, Google Cloud [global external HTTP(S) load balancer](/load-balancing/docs/https).\n- PSC is supported with [VPC Service Controls](/apigee/docs/api-platform/security/vpc-sc).\n- You can set an outlier detection traffic policy on the backend service for handling\n failover scenarios automatically. See the following for more information:\n\n - [Traffic policies](/load-balancing/docs/https/traffic-management-global#traffic_policies)\n - [Configure outlier detection](https://cloud.google.com/load-balancing/docs/https/setting-up-global-traffic-mgmt#configure_outlier_detection)\n - [REST\n Resource: backendServices](/compute/docs/reference/rest/v1/backendServices)\n\n| **Note:** If you currently use the MIG-based approach, you can migrate your system to PSC-based northbound routing. See [Migrate northbound routing from to PSC](/apigee/docs/api-platform/system-administration/migrate-from-mig-to-psc).\n\n**Figure 1: Private service connections**\n\nRestrictions\n------------\n\n\nThe use of PSC with Apigee currently has the following restrictions:\n| **Restrictions:** Note the following restrictions for PSC configuration:\n|\n| - [Global\n| external HTTP(S) load balancer (classic)](/load-balancing/docs/https) is not supported for this configuration.\n| - For failover with multiple PSC NEGs, active health checks are not supported. Use [outlier detection](/load-balancing/docs/https/traffic-management-global#traffic_policies) instead.\n| - Limits apply to the number of Google Cloud projects that can connect to an Apigee instance through PSC, and to the number of PSC NEG connections that you can have per project. For details, see [Private Service Connect (PSC) Limits](/apigee/docs/api-platform/reference/limits#private-service-connect-psc).\n| - If a Google cloud project is removed from `consumerAcceptList`, the existing PSC NEGs in that removed project will continue to work. However, any new NEGs will be rejected. You must delete existing NEGs if you remove their associated projects from the `consumerAcceptList`. Alternatively, you can recreate the Apigee instance, which recreates the service attachment in the Apigee project.\n\nUpdating the consumer accept list for an Apigee instance\n--------------------------------------------------------\n\nOn October 10, 2024, the limit on PSC NEG connections allowed per project to an Apigee instance was raised from\n20 to 100. For any Apigee instances created before that date, you must perform the steps in\nthis section to update the consumer accept list to take advantage of the new limit. You only need to upgrade each\nApigee instance once to receive the new connection limit. See also\n[Private Service Connect (PSC) Limits](/apigee/docs/api-platform/reference/limits#private-service-connect-psc).\n\nIf you need to have more than 1000 PSC NEG connections in total across all of the\nCloud projects connected to an Apigee instance, contact [Google Cloud Support](/apigee/docs/support/getting-started-with-support).\n\nTo update the consumer accept list of an Apigee instance\nto take advantage of the higher connection limit, do the following steps: \n\n### Cloud console\n\nFor detailed steps, see [Edit the accepted projects list](/apigee/docs/api-platform/system-administration/instances#accepted-projects).\n\n### Apigee API\n\nEdit the existing consumer accept list for your Apigee\ninstance. To use the [instances\nAPI](/apigee/docs/reference/apis/apigee/rest/v1/organizations.instances):\n\n1. Get the authentication token for the Apigee API: \n\n ```\n TOKEN=\"$(gcloud auth print-access-token)\"\n ```\n2. Get the list of Cloud projects in an instance's consumer accept list: \n\n ```\n curl https://apigee.googleapis.com/v1/organizations/PROJECT_ID/instances/INSTANCE_ID \\\n -H \"Authorization: Bearer $TOKEN\" -H Content-Type:application/json | jq .consumerAcceptList\n ```\n3. Create a JSON file named `update_consumer_accept_list.json` that contains the current list of accepted projects returned by the previous command. For example: \n\n ```\n {\n \"consumerAcceptList\": [\n \"dg-runtime-test1\",\n \"ne24b79b92c7db623p-tp\",\n \"dg-runtime-test2\",\n \"jd2fee78402218863p-tp\"\n ]\n }\n ```\n4. Optionally, edit the file to add more projects.\n5. Update the instance, using the JSON file you created as input. For example: \n\n ```\n curl https://apigee.googleapis.com/v1/organizations/PROJECT_ID/instances/INSTANCE_ID?updateMask=\"consumer_accept_list\" \\\n -X PATCH -H \"Authorization: Bearer $TOKEN\" -H Content-Type:application/json -d @update_consumer_accept_list.json\n ```\n\nConfigure PSC routing\n---------------------\n\n\nWe support using PSC for northbound routing from both internal and external clients. For detailed steps,\nsee [Step 8: Configure routing](/apigee/docs/api-platform/get-started/install-cli#configure-routing) of\nthe CLI provisioning instructions.\n\nMulti-region expansion with PSC\n-------------------------------\n\nYou can expand an Apigee organization across multiple regions and use PSC for northbound routing in the new regions. For details, see [Expanding Apigee to multiple regions](/apigee/docs/api-platform/system-administration/multi-region).\n\nDeleting an Apigee instance\n---------------------------\n\n\nTo delete an Apigee instance that uses PSC, follow these steps:\n\n1. [Remove and delete the PSC NEG backend](https://cloud.google.com/load-balancing/docs/cleaning-up-lb-setup#deleting_the_negs) from the external load balancer.\n2. Delete the Apigee runtime instance using the [Apigee API](/apigee/docs/reference/apis/apigee/rest/v1/organizations.instances/delete). This is a long-running operation that can take up to 20 minutes to complete.\n3. Optionally retrieve the long-running operation state using the [Apigee API](/apigee/docs/reference/apis/apigee/rest/v1/organizations.operations/get)."]]
