### Use cases: external service

An example could be that you have an external authentication provider that you need to call.

You send it a token and it returns an authenticated user.

This provider might be charging you per request, and calling it might take some extra time than if you had a fixed mock user for tests.

// Step takes a string provided from a server (or just an empty string for the
// very first conversation step) and attempts to move the authentication
// conversation forward.  It returns a string to be sent to the server or an
// error if the server message is invalid.  Calling Step after a conversation
// completes is also an error.

Ein **Container** wird von einem **Containerimage** ausgeführt.

Ein Containerimage ist eine **statische** Version aller Dateien, Umgebungsvariablen und des Standardbefehls/-programms, welche in einem Container vorhanden sein sollten. **Statisch** bedeutet hier, dass das Container-**Image** nicht läuft, nicht ausgeführt wird, sondern nur die gepackten Dateien und Metadaten enthält.

// Note that publish is always non-blocking send so that we don't block on slow receivers.
// Hence receivers should use buffered channel so as not to miss the published events.
