NINANS - Ninans Is Not A Naming Standard

Introduction

There are a number of public cloud providers who offer services in different geographic regions. Regions are always named differently across providers. Some people like to deploy things in multiple clouds. Some people like to encode information in the names of the resources they deploy in clouds. This may or may not be a good idea.

It may be useful to name stuff consistently, regardless of which cloud provider or region you use. That's NINANS.

Principles

  • Concise. Some systems require short hostnames (e.g. NetBIOS = 15 characters). Leave spare characters for local naming components.
  • Compatible. Lower case letters and numbers only and start with a letter.
