Aws Lambda and Ruby serverless application development is made easier by the Jets framework, which combines the experience of building a Rails application with the ability to deploy to AWS Lambda and related services. To get started with Jets, you can install the `jets` gem globally and create a new project using the `jets new` command. The Jet's controller generator will create a basic structure for your application, including models, controllers, actions, and routes. In this example, we built an SMS-based app that responds to incoming messages with a random dad joke from the icanhazdadjoke API. To deploy the application to AWS Lambda, you need to set up IAM credentials and create a new user with the minimum required permissions. Once deployed, you can test the application using curl or by sending an SMS message to the Twilio number associated with your application URL. The Jets framework makes it easy to build serverless Ruby applications that can run on AWS Lambda.
