AWS Region

An AWS Region is a geographical area.
Each AWS Region consists of two or more availability zone.
When we store data in a specific Region, it is not replicated outside that Region. It is our responsibility to replicate data across Regions, if our business needs require it.
Communication between Region uses AWS backbone network infrastructure.
To achieve fault tolerance and stability, regions are isolated from one another.

Fault tolerance refers to the ability of a system to continue operating without interruption when one or more of its components fail.

Things to take care while selecting any region

Data governance and legal requirements
Proximity to customers (latency)
Services available within the region
Costs (vary by region)
