to dynamically pass settings to your function code and libraries, without making changes to your
code. Environment variables are key-value pairs that you create and modify as part of your
function configuration, using either the AWS Lambda Console, the AWS Lambda CLI or the AWS
Lambda SDK.
"IAM Roles" - IAM roles help you with configuring permissions
"Timeouts" - Timeouts help with preventing your Lambda function from running indefinitely
"Aliases" - AWS Lambda aliases are pointers to a specific Lambda function version
