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 a site-to-site IPsec VPN

Whenever it comes to interconnecting your on-premises network to a Google Cloud VPC, you have an option of configuring a site-to-site IPsec VPN. This solution can provide an easy way to interconnect your networks while preserving information security. A site-to-site IPsec VPN requires a Cloud VPN in GCP and an IPsec gateway on the other side.


The maximum throughput you can reach with a site-to-site IPsec VPN is 3 gigabits per second.

There are three routing options, as outlined here:

  • Dynamic routing: This uses Border Gateway Protocol (BGP).
  • Route-based VPN: You only specific a list of remote IP ranges; those ranges are used only to create routes in your VPC network to peer resources.
  • Policy-based routing: Local IP ranges and remote IP ranges are defined as part of the tunnel creation process.

    You can see these routing options in the following screenshot:
