A Google Virtual Private Cloud (VPC) network is an isolated environment that provides the underlying network components for your cloud resources. VPC network peering is the act of connecting two or more VPC networks together to allow communication between resources within Google's secure, private network. This means any traffic between resources is not sent over the public Internet which can improve network security, and reduce network latency and costs.

In this lab, you will create a VPC network peering connection between two networks. You will learn which VPC network components are automatically shared between networks, and which components you must update after the connection is established. To validate the network peering connection, you will attempt to send simple requests between Compute Engine instances in the separate VPC networks.

Learning Objectives

Upon completion of this intermediate-level lab, you will be able to:

• Create a peering connection between two Google VPC networks
