This tutorial guides users in creating a serverless user verification service using Python, Twilio Verify, and the Chalice Framework. The application exposes API endpoints to send verification codes via SMS and verify them once received by the user. To deploy the application, users need an AWS account and a free Twilio account with verified phone numbers. The tutorial covers setting up environment variables for the Twilio credentials, creating a new Chalice project, deploying it to AWS Lambda, and testing the API endpoints using curl. Although the application is deployed successfully, it lacks authentication mechanisms to prevent malicious usage and charges against the AWS account.
