This tutorial guides developers through creating and deploying an AWS Lambda function that uses Python and connects to a CockroachDB Serverless database. The process involves setting up an AWS account, creating an IAM user, installing the AWS CLI, creating a CockroachDB Serverless cluster, cloning the Python function, creating a deployment package, configuring AWS, deploying the function to AWS Lambda, and invoking the function. The tutorial also provides optional steps for using the CockroachDB SQL shell to view results.
