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
• 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: reduced 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

• Each region has many availability zones (usually 3, min is 2, max is 6)
• Names can be ap-southeast-2a, ap-southeast-2b, ap-southeast-2c...
• 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
