Question

You have several microservices running in a private subnet in an existing Virtual Private Cloud (VPC). You need to create additional serverless services that use Cloud Run and Cloud Functions to access the microservices.

You want to implement a solution that minimizes cost. What should you do?

Explanation

Serverless VPC Access is based on a resource called a connector. A connector handles traffic between your serverless environment and your VPC network. When you create a connector in your Google Cloud project, you attach it to a specific VPC network and region. You can then configure your serverless services to use the connector for outbound network traffic. https://cloud.google.com/vpc/docs/serverless-vpc-access
