Overview
Virtual Private Cloud (VPC) networks allow you to maintain isolated environments within a larger cloud structure, giving you granular control over data protection, network access, and application security.
In this lab you create several VPC networks and VM instances, then test connectivity across networks. Specifically, you create two custom mode networks (managementnet and privatenet) with firewall rules and VM instances as shown in this network diagram:
The mynetwork network with its firewall rules and two VM instances (mynet-vm-1 and mynet-vm-2) have already been created for you for this lab.
Objectives
In this lab, you will learn how to perform the following tasks:
- Create custom mode VPC networks with firewall rules
- Create VM instances using Compute Engine
- Explore the connectivity for VM instances across VPC networks
- Create a VM instance with multiple network interfaces
Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.

VPC networks are by default isolated private networking domains. However, no internal IP address communication is allowed between networks, unless you set up mechanisms such as VPC peering or VPN.
Task 4. Create a VM instance with multiple network interfaces
Every instance in a VPC network has a default network interface. You can create additional network interfaces attached to your VMs. Multiple network interfaces enable you to create configurations in which an instance connects directly to several VPC networks (up to 8 interfaces, depending on the instance's type).
Create the VM instance with multiple network interfaces
Create the vm-appliance instance with network interfaces in privatesubnet-1, managementsubnet-1 and mynetwork. The CIDR ranges of these subnets do not overlap, which is a requirement for creating a VM with multiple network interface controllers (NICs).
