The IBM Application Gateway (IAG) provides a containerized secure Web Reverse proxy which is designed to sit in front of your application, seamlessly adding authentication and authorization protection to your application.

Defining the Environment

At a high level, when starting the IAG container you need to define:

1. The identity source for the environment. The container is able to protect applications by acting as an OIDC Relying Party, and protect API's using OAuth token introspection;
2. The applications which are to be protected. For each application you might potentially need to define:
   1. The Web servers which host the application;
   2. The authorization policy for the application resources;
   3. Any rate limiting rules to help manage access to the application;
   4. Any transformations which should take place on either the HTTP request or response.
