AWS Cloud Development Kit - From Beginner to Professional - Serverless: Create Lambda for Event-Driven Architecture

The video tutorial covers AWS Lambda functions, focusing on their use in serverless applications. It explains how to set up a CDK project, build and deploy a Lambda function, configure runtime and environment variables, and test the function. The tutorial also discusses permissions and the automatic provisioning of IAM roles. Finally, it demonstrates how to clean up resources using CDK destroy, while retaining CloudWatch log groups for troubleshooting and compliance.

What is a primary benefit of using AWS Lambda functions?

• They allow you to manage servers more efficiently.

• They enable code execution in response to events without server management.

• They are used for data storage solutions.

• They provide a platform for building mobile applications.

In the CDK project setup, what is the purpose of the 'Cornerstone processor' file?

• It stores application data.

• It logs events and returns a JSON response.

• It configures the server settings.

• It manages user authentication.

Which runtime is chosen for the Lambda function in the custom stack?

• Node.js

• Java

• Python 3.7

• Ruby

What is the maximum duration a Lambda function can run?

• 5 minutes

• 10 minutes

• 15 minutes

• 20 minutes

How does CDK handle IAM roles for Lambda functions?

• It automatically provisions the necessary IAM roles.

• It uses default roles without customization.

• It requires manual setup of IAM roles.

• It does not support IAM roles.

What happens to CloudWatch logs when a stack is destroyed?

• They are archived for future use.

• They remain intact for troubleshooting.

• They are moved to a different account.

• They are automatically deleted.

Why might you want to retain CloudWatch logs after deleting a Lambda function?

• To increase security.

• To improve function performance.

• For compliance and archival purposes.

• To reduce storage costs.
