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.

Logging and monitoring with GCP operations

In this section, you will learn how to enable and monitor logging on your VPC. First, we will explore how to log VPC flows. Then we will learn how to enable logging in firewall rules and monitor them. Lastly, we will enable VPC audit logs and monitor them. We will use Cloud Logging and Cloud Monitoring in the following exercises.

VPC Flow Logs

There are multiple use cases for VPC Flow Logs. For instance, when you need to determine where your application is being accessed, VPC Flow Logs can help to investigate. Moreover, when you need to build a Cloud Armor blacklist of unwanted IP addresses, VPC Flow Logs can provide such information.

Going into more detail, when you enable VPC Flow Logs on your VPC, you will be able to collect network traffic samples that are sent or received by Compute Engine instances or Google Kubernetes Engine (GKE) nodes. These logs are stored in Cloud Logging and can be used for network monitoring, network...
