Introduction to AZs and Regions

Availability Zones and Regions are the core components within AWS that allow for fault isolation.

The AWS global infrastructure is made up of multiple geographic regions spread around the world. They are connected via high-speed networking but are independent.

An AWS region is made up of multiple Availability Zones. These Availability Zones allow for fault isolation within a region and provide the simplest way to achieve a significant level of redundancy.
