What are Availability Zones in Snowflake?

1. Individual servers in a data center

2. Standalone regions without redundancy

3. Data centers in certain regions

4. Temporary storage locations

The correct answer is: Data centers in certain regions

Availability Zones in Snowflake refer to distinct data centers within a cloud region that provide redundancy and high availability for workloads. Each zone is designed to be independent from others in terms of power, cooling, networking, and physical security, which helps to ensure that if one zone experiences an outage, the others can continue to operate smoothly. This architecture enhances reliability and disaster recovery capabilities, making it easier for Snowflake to maintain uptime and data integrity. The existence of multiple Availability Zones is crucial for organizations that require robust service continuity and resilience. In contrast, individual servers in a data center do not capture the concept of redundancy offered by Availability Zones. Standalone regions without redundancy do not embody the principles of availability that Availability Zones are intended to provide. Temporary storage locations also do not represent the infrastructure and resilience aspect that Availability Zones encompass, as they pertain to data handling rather than structural reliability within the service framework.
