AWS Lambda is a serverless computing platform that enables you to run programs in response to events without having to configure and administer servers. AWS Lambda Layers are ZIP archives that contain libraries, a custom runtime, or other dependencies, allowing you to separate function code from its dependencies and save time when packaging and deploying Lambda functions. The Twilio Node.js Helper Library can be used with AWS Lambda Layers to send voice and text messages without requiring extensive code modifications. By following this tutorial, users can create an AWS Lambda Layer containing the Twilio Node Helper Library and add it to their Lambda functions, enabling them to send text messages using Twilio's library without including it in their deployment package. This allows for more efficient maintenance and reduces the size of the deployment package. Additionally, users can test and schedule their Lambda function using CloudWatch triggers, allowing for automated execution at a specified time.
