AWS Global Infrastructure

Explore Regions, Availability Zones, and Edge Locations, and learn how to choose the right Region for your workload.

AWS Regions Explained

An AWS Region is a geographic area holding several isolated zones. There are 30+ worldwide, and each is independent — great for data-residency rules. The code lists them.

# List all available AWS Regions
aws ec2 describe-regions --query 'Regions[].RegionName' --output table

Availability Zones: Fault Isolation

Each Region has multiple Availability Zones — separate data centres with their own power and networking. Spread across them and one failure won't take you down.

# Describe Availability Zones in the current region
aws ec2 describe-availability-zones \
  --query 'AvailabilityZones[].ZoneName' \
  --output table
