# AWS Regions

• AWS has Regions all around the world

• Names can be us-east-1, eu-west-3...

• A region is a cluster of data centers

### How to choose an AWS Region?

• **Compliance** with data governance and legal requirements: data never leaves a region without your explicit permission

• **Proximity** to customers: reduced latency

• **Available services** within a Region: new services and new features aren’t available in every Region

• **Pricing**: pricing varies from region to region and is transparent on the service pricing page
