Google Cloud Certified Professional Cloud Network Engineer Guide

By: Maurizio Ipsale, Mirko Gilioli

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.

Diving into Cloud Router

Cloud Router is a Google Cloud service that emulates the standard behavior of a real physical IP router. It is not a physical device (and so it cannot cause bottlenecks), but indeed it is a service, fully managed and distributed (it can work whether regionally or globally to the entire GCP suite). Being a fully managed service, it is also automatically scalable to satisfy the dynamic needs of your VPC network.

When used in cooperation with an interconnect option, between your on-prem network and your VPCs, it uses the BGP protocol to dynamically exchange routes between your networks.


BGP is one of the most important (or maybe the most important) routing protocols used on the entire internet nowadays. It is responsible for exchange routing information among different ASes.

ASes are connected groups of one or more IP prefixes run by one or more network operators that have a single and clearly defined routing policy (see IETF RFC 1930, March 1996...
