What is 'Zone Redundancy' in the context of Google Cloud?

Zone Redundancy in the context of Google Cloud refers to the strategy of hosting resources across multiple zones within a region. This design is crucial for ensuring high availability and resilience of applications and services. By distributing resources across different zones, Google Cloud provides customers with the ability to maintain service continuity even in the event of an outage or failure in one of the zones. Each zone is designed to be independent and isolated from failures in other zones, which enhances the overall reliability of services.

Using zone redundancy, organizations can deploy their applications such that if one zone experiences issues, the application can automatically failover to another zone seamlessly, thereby minimizing downtime and ensuring that users have access to the needed resources. This redundancy is particularly important for mission-critical applications where downtime can lead to significant business impact.
