In this post, learn how to leverage the AWS Cloud Development Kit (CDK) to build and deploy a serverless AWS Lambda function that uses Twilio’s Programmable SMS API to send SMS to users. We will use Java for all components of this post to define the AWS CDK application and AWS Lambda Handler, and we will use Twilio’s Java Helper Library to work with the SMS APIs.

For this tutorial, you will need to set up Java on your system, since we will be using it to define our AWS CDK application and the AWS Lambda handler. In addition to it, you will need to install AWS CLI and AWS CDK CLI, to configure AWS credentials and to build your CDK application respectively. Finally, you will need to create an AWS account for deploying the application, and a Twilio account with an SMS-enabled phone number to send SMS. Refer …
