How does the serverless.yml file facilitate the deployment and management of serverless applications and what are its key components?

The serverless.yml file is used only for defining environment variables for AWS Lambda functions and it does not impact resource deployment.

The serverless.yml file defines the service configuration, including functions, events, and resources, enabling the Serverless Framework to automate deployment and manage cloud infrastructure.

The serverless.yml file serves as a configuration template for the AWS CloudFormation stack and is primarily used for setting user permissions for the serverless application.

What steps are involved in using the serverless deploy command and how does it ensure that all resources and functions are correctly provisioned and configured in AWS?

The serverless deploy command only packages the application code into a ZIP file and uploads it to an S3 bucket without provisioning any infrastructure.

The serverless deploy command packages the application, generates an infrastructure template, uploads the artifacts, and executes the deployment, provisioning all defined resources and functions automatically.

The serverless deploy command executes the application locally and prints logs to the console but does not interact with AWS services.

How can you configure an AWS Lambda function to interact with a DynamoDB table and what are the benefits of using ES Modules and IAM roles in this context?

AWS Lambda functions cannot directly interact with DynamoDB tables; they must use an intermediate service like S3 to access data.

You configure an AWS Lambda function to interact with a DynamoDB table by using the AWS SDK to perform read/write operations and defining IAM roles to manage permissions, while ES Modules provide a modern syntax for importing dependencies and organizing code.

AWS Lambda functions require a direct connection string to the DynamoDB table and ES Modules are not supported in AWS environments, making CommonJS the only viable module system.
