AWS Regions

  • AWS has Regions all around the world
     
  • Names can be us-east-1, ap-south-1
     
  • A region is a cluster of data centres
     
  • Most AWS services are region-scoped

AWS Availability Zones

• Each region has many availability zones (usually 3, min is 2, max is 6). Example: • 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
