Create an alias for a Lambda function
You can create aliases for your Lambda function. A Lambda alias is a pointer to a function version that you can update. The function's users can access the function version using the alias Amazon Resource Name (ARN). When you deploy a new version, you can update the alias to use the new version, or split traffic between two versions.
