Architecture for private communication with GCP Managed Service on AWS

In the last post, we talked about how to create a private service connection (GCP PSC) and make PSC ip available in aws as well. However, in order to use the actual GCP apis, we also need to set up a private DNS zone for `googleapis.com ‘ and register a record for PSC IP.

There are three ways that resources within AWS VPC can query the domain ‘googleapis.com ‘.

1. Use public DNS Zone owned by google
2. Make googleapis.com Private DNS Zone in GCP Cloud DNS
3. Make googleapis.com Private DNS Zone in AWS Route53

• First, the first method is to use the DNS zone for domain '.googleapis.com' because Google already has a DNS zone configured for public ip to be queried in the domain '. However, the previously created PSC ip cannot be registered as a domain record of '.googleapis.com ' here, so it cannot be used in the current scenario.
• Both methods 2 and 3 are applicable to the current scenario because they configure a private DNS zone that allows the customer to query the domain…
