Which architecture best fit the requirements, considering its original requirement for AWS?

[gungkrisna]

I have a requirement to create a VPC diagram originally designed for AWS but now need to adapt it for implementation in GCP. Which design would satisfy this requirement, and how can I ensure its correctness? Here is the diagram URL

1. The architecture is high-availability (in AWS, it should have multi AZs).

2. Determine the appropriate IP address range for each subnet.

3. There are public and private subnets.

4. Use some components in the VPC, including:
   Internet gateway (I have no idea about the equivalent service in GCP)
   VPC peering

5. Design the architecture in the private data center.

6. The private data center can connect to resources in AWS.
