<a name="ar-resilience"></a>

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. 

For more information about AWS Regions and Availability Zones, and how AWS achieves resilience goals, see [AWS Global Infrastructure](http://aws.amazon.com/about-aws/global-infrastructure/).
