Google Cloud Platform Administration

By: Ranjit Singh Thakurratan

Overview of this book

On-premise data centers are costly to manage. If you need a data center but don’t want to deal with a physical one, Google Cloud Platform (GCP) is the solution. With GCP, you can build, test, and deploy applications on Google’s infrastructure. Google Cloud Platform Administration begins with GCP fundamentals, with the help of which you will deploy your first app and gain an understanding of Google Cloud architecture and services. Furthermore, you will learn how to manage Compute, networking, and storage resources. As you make your way through the book, you will learn how to track and manage GCP’s usage, monitoring, and billing access control. You will also be able to manage your GCP's access and permissions. In the concluding chapters, you will explore a list of different developer tools for managing and interacting with the GCP platform. By the end of this book, you will have learned how to effectively deploy workloads on GCP.

Firewall rules in GCP let you allow or deny traffic based on rules you apply to your instances. Firewall rules are applied at a networking level with every VPC network acting as a distributed firewall. Even though firewall rules are applied at a networking level, they allow/deny connections at an instance level. The advantage of a distributed firewall is that it does not only filter traffic between instances but also filters traffic between networks. All firewall rules are specific to a VPC network with each rule either allowing or denying traffic.

Firewall rules, being unique to a VPC network, cannot be shared between multiple VPC networks. It is important to note that firewall rules in GCP only support IPv4 traffic. There is also no logging mechanism for firewall rules; this means that you cannot log an Allow or a Deny action in the firewall. The GCP firewall allows...
