     * <p>
     * A function has an unpublished version, and can have published versions and aliases. The unpublished version

     * <code>1</code> of your function from its initial configuration.
     * </p>
     * <p>
     * The other parameters let you configure version-specific and function-level settings. You can modify
     * version-specific settings later with <a>UpdateFunctionConfiguration</a>. Function-level settings apply to both
     * the unpublished and published versions of the function, and include tags (<a>TagResource</a>) and per-function
