Regions & AZ
AWS Regions
Regions all the world.
Names can be us-east-1, eu-west-3 etc.
Cluster of data centres.
Most AWS services are region scoped.
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: reduce latency
Available services within a Region: new services and new features aren't available in every Region
Pricing: pricing varies region to region and is transparent in the service pricing page
AWS Availability Zones (AZ)
Each region has many availability zones (usually 3, min 3, max 6). e.g. ap-southeast-2a, ap-southeast-2b, ap-southeast-2c
Each AZ is one or more discrete data centres with redundant power, networking and connectivity.
Separate from each other so they are isolated from disasters.
Connected with hight bandwidth, ultra-low latency networking.
