Google Cloud resource hierarchy

Very similar to AWS’s global infrastructure, Google Cloud has global data centers where the physical facilities and data resides. Each data center has redundant power, networking, and connectivity, and there are Google backbone networks connecting them. These data centers compose the Google Cloud, which is divided into regions and zones, like AWS Regions and AZs. Figure 8.1 shows the Google global regions at the time of writing this book:

In the previous chapter, we discussed the AWS resource hierarchy, which consists of a root organization, Organization Units (OUs), and AWS accounts, from top to bottom. In GCP, the resource hierarchy consists of four main layers, as shown in Figure 8.2:
