The Google Cloud Network

The Google Cloud network connects applications, services, and users across Google’s infrastructure. It is an important foundation for building applications that need to communicate reliably and serve users in different locations.

Regions and Zones

Google Cloud infrastructure is organized into regions and zones.

• Region: A geographic location where Google Cloud resources are hosted.
• Zone: A specific deployment area within a region.

Using multiple zones can help applications improve availability and resilience.

Why Networking Matters

Applications often need to communicate with:

• Other applications
• Databases
• Storage services
• Users over the internet
• Systems running outside Google Cloud

A well-designed network helps control connectivity, performance, security, and availability.

Google Cloud Networking

Google Cloud provides networking capabilities that allow resources to communicate within Google Cloud and connect to external networks.

Google Cloud networking provides the connectivity that allows users, applications, and cloud resources to communicate.

Remember:
Region = geographic area
Zone = deployment area within a region
