Google Cloud Platform for Architects

By: Vitthal Srinivasan, Loonycorn , Judy Raj

Overview of this book

Using a public cloud platform was considered risky a decade ago, and unconventional even just a few years ago. Today, however, use of the public cloud is completely mainstream - the norm, rather than the exception. Several leading technology firms, including Google, have built sophisticated cloud platforms, and are locked in a fierce competition for market share. The main goal of this book is to enable you to get the best out of the GCP, and to use it with confidence and competence. You will learn why cloud architectures take the forms that they do, and this will help you become a skilled high-level cloud architect. You will also learn how individual cloud services are configured and used, so that you are never intimidated at having to build it yourself. You will also learn the right way and the right situation in which to use the important GCP services. By the end of this book, you will be able to make the most out of Google Cloud Platform design.

Internal and external IP addresses

Resources that are in the same VPC can communicate using internal IP addresses, as well as using a project-internal DNS facility. This is true even if the resources are in different regions. For instance, consider two VMs, one in the US and the other in the UK; provided these are in the same VPC, they will be able to communicate using internal IP addresses despite their physical distance.

By contrast, if two resources are in different VPCs, even if they happen to be in the same region or even on the same underlying bare metal box (remember that GCP VMs are multi-tenanted), they will still have to communicate using external IP addresses, which implies that the network traffic between them will have to pass over the internet (or Google’s global network in this case).

Internal IP addresses are assigned from the subnet range using the familiar...
