Google Cloud Platform (GCP) - Shared VPC

In this tutorial, you will learn how to setup Shared VPC and how to attach multiple service projects to it. You will also learn how to use it in service projects to deploy workloads.
Shared VPC allows an organization to connect resources from multiple projects to a common Virtual Private Cloud (VPC) network, so that they can communicate with each other securely and efficiently using internal IPs from that network. When you use Shared VPC, you designate a project as a host project and attach one or more other service projects to it. The VPC networks in the host project are called Shared VPC networks. Eligible resources from service projects can use subnets in the Shared VPC network.
