AWS Cloud Development Kit - From Beginner to Professional - Serverless REST API Architecture: APIGW, Lambda, and DynamoD

The video tutorial covers building a serverless REST API architecture using AWS services. It starts with an introduction to REST API and API Gateway, followed by using AWS Lambda for business logic and DynamoDB for storage. The tutorial then guides through setting up a CDK stack, creating a DynamoDB table, and a Lambda function. It also covers constructing an API Gateway and integrating it with Lambda. Finally, the video demonstrates testing the setup and troubleshooting permission issues.

What is one of the primary roles of an API Gateway in REST API architecture?

• To provide a user interface

• To store user data

• To manage authentication and access

• To process business logic

Which AWS service is recommended for handling business logic in a serverless architecture?

• Amazon S3

• AWS Lambda

• Amazon RDS

• Amazon EC2

What type of database is used for backend storage in the discussed architecture?

• Graph Database

• Document Database

• Relational Database

• Key-Value Store

What is the first step in setting up the serverless stack using AWS CDK?

• Importing necessary modules

• Configuring API Gateway

• Writing Lambda function code

• Deploying the stack

What is the primary key type used in the DynamoDB table setup?

• Boolean

• Binary

• String

• Number

What is the purpose of creating a log group for the Lambda function?

• To handle user authentication

• To clean up logs when the environment is deleted

• To manage API keys

• To store user data

What method is used to capture user likes in the API Gateway?

• DELETE

• POST

• GET

• PUT

What should be done if the Lambda function lacks permission to write to DynamoDB?

• Add read permissions

• Grant read-write permissions

• Change the primary key

• Increase the timeout

What indicates a successful update in the DynamoDB table during testing?

• An error message

• A new item in the table

• A timeout error

• A log entry

What is the final step after fixing code errors in the API setup?

• Rewriting the code

• Re-deploying the stack

• Deleting the stack

• Changing the API Gateway
