How many availability zones does Snowflake replicate data to for disaster recovery?

  1. Zero

  2. One

  3. Three

  4. As many as specified by the user

The correct answer is: Three

Snowflake replicates data to three availability zones for disaster recovery. This replication strategy is designed to provide high availability and resilience in the face of potential system failures or other disruptions. By utilizing multiple availability zones, Snowflake ensures that user data remains accessible and recoverable, minimizing the risk of data loss and downtime. The architecture leverages these multiple zones within its cloud infrastructure, allowing for seamless failover and redundancy. If one zone experiences an issue, the data remains safe and can be quickly accessed from another zone. This multi-zone approach is part of Snowflake’s commitment to reliability and performance, ensuring that customers can maintain business continuity even in adverse conditions.
