The following image depicts how Red HAT SREs and other internal resources access and support clusters created using PSC.
* A unique PSC Service Attachment is created for each OSD cluster in the customer GCP project. The PSC Service Attachment points to the cluster API server load balancer created in the customer GCP project.

* Similar to service attachments, a unique PSC endpoint is created in the Red Hat Management GCP project for each OSD cluster.
* A dedicated subnet for GCP Private Service Connect is created in the cluster’s network within the customer GCP project. This is a special subnet type where the producer services are published via PSC Service Attachments. This subnet is used to Source NAT (SNAT) incoming requests to the cluster API server. Additionally, the PSC subnet must be within the Machine CIDR range and cannot be used in more than one Service Attachment.
