# How to choose an AWS Region?
- COMPLIANCE with data governance and legal requirements: data never leaves a region without your explicit permission
- Latency: Choosing an AWS Region with close proximity to your user base location can achieve lower network latency
- Services and Features: new services and new features aren't available in every region
- PRICING: pricing varies region to region and is transparent in the service  page 
   
# AWS Availability Zones

(usually 3, min is 2, max is 6). 
- Example: us-east-1a, us-east-1b, us-east-1c
- Each availability zone (AZ) is one or more
discrete data centers with redundant power,
networking, and connectivity
- They’re separate from each other, so that
they’re isolated from disasters
- They’re connected with high bandwidth,
ultra-low latency networking
