Running from EC2 Instance vs. Local

When running on an EC2 instance the prefered approach is to configure the Application, SDLC and Component as the instance tags. However, if there is a usecase where one does NOT want to use the EC2 instance tags (example: jenkins build on a generic EC2 slave), then the environment variables CRED_Application, CRED_SDLC and CRED_COMPONENT can be configured which will take higher priority.

Example using environment variables:

CRED_Application=APP
CRED_Component=database
CRED_SDLC=dev

When running locally, the prefered approach is to set the environment variables. However, if there is a usecase to call the getCredential and putCredential multiple times with different Application/SDLC/Component values, then pass those values directly to the APIs.
