Google Cloud regions and zones
1. Google Cloud regions and zones
Google has invested billions of dollars over the years to build its network, which is one of the largest networks of its kind on Earth. It’s designed to give customers the highest possible throughput and lowest possible latencies for their applications. Google Cloud’s infrastructure is based in seven major geographic locations: North America, South America, Europe, Africa, the Middle East, Asia, and Australia. Having multiple service locations is important because choosing where to locate applications affects qualities like availability, durability, and latency—the latter of which measures the time a packet of information takes to travel from its source to its destination. Each of these locations is divided into several different regions and zones. Regions represent independent geographic areas and are composed of zones. For example, London, or europe-west2, is a region that currently comprises three different zones. A zone is an area where Google Cloud resources are deployed. For example, if you launch a virtual machine using Compute Engine, it will run in the zone that you specify to ensure resource redundancy. You can also run resources in different regions. This is useful for bringing applications closer to users around the world and also for protection in case there are issues with an entire region, such as a natural disaster. Some of Google Cloud’s services support placing resources in what we call a multi-region. For example, Cloud Storage lets you place data within the Europe multi-region. This means it's stored redundantly in at least two geographic locations, separated by at least 160 kilometers within Europe, such as London and Belgium. You can find the most up-to-date numbers for Google Cloud regions and zones at cloud.google.com/about/locations.2. Let's practice!
