Configuring Lambda Web Functions

You configure most Web Function settings on a revision, which is an immutable snapshot of your application code and configuration. Because a revision is immutable, changing a revision setting means creating a new revision with the updated values. You set tags and the resource-based policy on the Web Function. Its revisions and endpoints inherit its tags, and the resource-based policy controls who can act on the Web Function, its revisions, and its endpoints. Endpoint settings apply to each endpoint, including authentication type, auto-deployment mode, revision weights, scaling, and throttling. You can change these without creating a new revision. The following topics describe the settings you can configure.
