Regions and Availability Zones
An AWS Region is a separate geographic area containing multiple Availability Zones. Availability Zones are distinct locations within a Region, designed so workloads can be distributed for resilience.
Why it matters
Region selection affects latency, service availability, compliance considerations and cost. Multiple Availability Zones can reduce dependence on a single location.
How it works
Choose a Region close to the intended users when appropriate, then place resilient resources across Availability Zones where the service and architecture support it.
Core Concept
A Region is a geographic area containing multiple Availability Zones.
Availability Zones are isolated locations within a Region designed to support resilient architectures.
