AWS – Common terminologies

AWS in it’s physical form is made up of a large number of data centers across the world. These data centers are independent of each other, meaning that if one data center goes down, it will not impact the others.

In AWS these data centres are referred to as Availability Zones.  These Availability Zones are organised into groups, based on geographical proximity, and each of these groups are referred to as  regions.

Making use of all the Availability Zones in a region  has several advantages:

  • low latency – if a AZ is close to an end user.
  • fault tolerance


The AWS console is designed to only interact with one region at a time, you can navigate between regions using the
