What is Region and Availability Zone?

Geographic locations where cloud providers operate data centers, with zones providing redundancy within a region.

Cloud regions are separate geographic areas (e.g., us-east-1, eu-west-1) with independent infrastructure. Availability Zones (AZs) are isolated data centers within a region, connected by low-latency links.

Deploying across multiple AZs provides high availability — if one zone fails, others continue operating. Deploying across regions provides disaster recovery and serves users closer to their location for lower latency.
