Regions and Zones

Google Cloud's physical infrastructure is housed inside globally distributed data centers comprehensively protecting data latency natively.

When deciding exactly where your specific infrastructure will logically run natively, there are two prime categorizations: Regions and Zones.

The Hierarchy​

Maps​

  • Regions: Independent geographic areas natively containing data centers explicitly (e.g., us-central1, europe-west4).
  • Zones: Highly isolated data center locations physically nested precisely inside a parent Region safely (e.g., us-central1-a, us-central1-b).

High Availability (HA) Design​

To securely survive an enormous natural disaster natively destroying a physical data center strictly, cloud structural architects heavily deploy databases securely scaling completely across multiple distinct Zones smoothly simultaneously within a single Region.

If an entire massive parent Region critically goes offline explicitly, global load-balancers heavily dynamically instantly re-route pure active network traffic cleanly into isolated secondary alternative Regions automatically!
