Performing an action that invokes a custom Amazon AppConfig extension

After you create the association, you can invoke the MyS3ConfigurationBackUpExtension extension by creating a new configuration profile that specifies hosted for its SourceUri. As a part of the workflow to create the new configuration, Amazon AppConfig encounters the PRE_CREATE_HOSTED_CONFIGURATION_VERSION action point. Encountering this action point invokes the MyS3ConfigurationBackUpExtension extension, which automatically backs up the newly created configuration to the S3 bucket specified in the Parameter section of the extension association.
