The tutorial discusses creating a Continuous Deployment (CD) environment for an AWS Lambda function using Bitbucket Pipelines and AWS SAM. It assumes familiarity with Git, Node.js, and AWS. The CD process involves setting up an IAM user, creating a Bitbucket repository, writing a SAM template to deploy the Lambda function, and configuring a Bitbucket pipeline to automate the deployment of code changes to the Lambda function. The tutorial also covers testing the deployed function using API Gateway and provides suggestions for extending the application further, including improving security and debugging capabilities.
