AWS Region Names

aws.md

Alternative naming schemes for AWS regions

Purpose

The intent is to define terse, standards-supported names for AWS regions.

"A" is equivalent to A2 in the chart above. I fixed the codes as noted in the comments. I also added new regions for 2018, 2019, 2020.

Imo ase looks better than apse. There's no Asia without Pacific right?

See also https://github.com/cloudposse/terraform-aws-utils/blob/master/main.tf for implementation of abbreviations via Terraform.

amazon uses cnn1 for cn-north-1, not cn1, see https://docs.aws.amazon.com/AmazonECS/latest/userguide/AWS_Fargate-Regions.html (and euc1, etc. not ec1, as mentioned by @rackerbenoit )

You wrong, use Region code, not Zone code https://awsregion.info/

@adv4000 I was just referring to that page that I linked to (on amazon.com, not 3rd party) where you can see that AWS uses cnn1 as an abbreviation for cn-north-1. Not sure why you think that's wrong? I understand the difference between region codes and Zone codes, but wouldn't it make sense to use a single abbreviation for both, eg. cnn1 for the region and cnn1-az1 for the zone?

In cost (CUR reports, Amazon uses an alternative set of abbreviations for regions: https://docs.aws.amazon.com/AmazonS3/latest/userguide/aws-usage-report-understand.html
Would it be useful to add a column with Amazon's abbreviations to this table?
