AWS Regions
A region is a cluster or collection of data centers.
AWS has regions all around the world.
Most AWS services are region-scoped.
How to choose 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 are not always available in every region.
Pricing: Pricing varies region to region.
AWS Availability Zones
Each Region can has many Availability Zones (usually 3, min 3, max 6).
Each AZ is one or more discrete data centers with redundant power, networking and connectivity.
They are separate from each other, so that they are isolated from disasters.
They are connected with high bandwidth, ultra-low latency networking.
