Overview of this book

Google Cloud, the public cloud platform from Google, has a variety of networking options, which are instrumental in managing a networking architecture. This book will give you hands-on experience of implementing and securing networks in Google Cloud Platform (GCP). You will understand the basics of Google Cloud infrastructure and learn to design, plan, and prototype a network on GCP. After implementing a Virtual Private Cloud (VPC), you will configure network services and implement hybrid connectivity. Later, the book focuses on security, which forms an important aspect of a network. You will also get to grips with network security and learn to manage and monitor network operations in GCP. Finally, you will learn to optimize network resources and delve into advanced networking. The book also helps you to reinforce your knowledge with the help of mock tests featuring exam-like questions. By the end of this book, you will have gained a complete understanding of networking in Google Cloud and learned everything you need to pass the certification exam.

Configuring and managing firewall rules

In this section, we investigate how to configure and manage firewall rules in a VPC network. Firewall rules are an important element of the VPC network because they implement security in your infrastructure. Let's begin by taking the following steps:

  1. First, we create a new mynetwork VPC with the Automatic subnet mode, as shown in the following screenshot:

    Figure 3.48 – Creating a VPC with Automatic subnet mode

  2. Then, we create a privatenetwork VPC with the Custom subnet mode, as shown in the following screenshot:

    Figure 3.49 – Creating a VPC with Custom subnet mode

  3. Since the subnet mode is Custom, we must create at least a custom subnet in the privatenetwork VPC, selecting the 10.0.0.0/24 IP address range, as can be seen in the following screenshot:

By means of the cloud shell, we will create some GCE...
