Amazon AWS pem key naming conventions

If application name is 'app', create application keys with app-name-availability-zone-purpose as convention, to have a nice way to organize access keys between availability zones and appliances and have good distribution of access

some examples of key names:

**production us-east-1 keys**

App-us-east-1-prod-cluster
App-us-east-1-prod-app

**development us-east-1 keys**

App-us-east-1-dev-cluster
App-us-east-1-dev-app

**production us-west-1 keys**

App-us-west-1-prod-cluster
App-us-west-1-prod-app

**development us-west-1 keys**

App-us-west-1-dev-cluster
App-us-west-1-dev-app
