GCP's infrastructure is designed for high availability, low latency, and global reach. Understanding how regions, zones, and Google's network work is essential for architecting reliable applications.
A region is an independent geographic area where GCP resources are hosted. Each region is designed to be isolated from failures in other regions.
Examples:
| Region Code | Location |
|---|---|
europe-west2 | London, UK |
us-central1 | Iowa, USA |
asia-east1 | Taiwan |
australia-southeast1 | Sydney, Australia |
me-central1 | Doha, Qatar |
GCP operates 40+ regions across the Americas, Europe, Asia-Pacific, and the Middle East.
Each region contains three or more zones. A zone is a deployment area within a region — think of it as one or more data centres with independent power, cooling, and networking.
