AWS Serverless Microservices with Patterns and Best Practices - Create a REST API from AWS Lambda Function by Adding API

The video tutorial demonstrates how to create and configure a REST API using AWS Lambda and API Gateway. It covers the process of setting up a Lambda function, adding API Gateway triggers, and testing the API endpoint. The tutorial emphasizes creating APIs directly from Lambda without using the API Gateway console, streamlining the process and ensuring efficient API management.

What is the main advantage of creating an API from a Lambda function with an API Gateway trigger?

• It simplifies the architecture by removing the need for an API Gateway.

• It reduces the cost of AWS services.

• It allows for faster deployment.

• It enhances the security of the API.

When creating a new Lambda function, what is the first step?

• Select the runtime environment.

• Open the AWS Management Console.

• Define the API endpoint.

• Configure the security settings.

How is a REST API created directly from AWS Lambda?

• By writing custom code in the Lambda function.

• By using the AWS CLI.

• By adding a trigger service in the AWS Management Console.

• By configuring the API Gateway manually.

What is the purpose of the API Gateway trigger in a Lambda function?

• To automatically scale the Lambda function.

• To reduce the execution time of the Lambda function.

• To route requests to the Lambda function and return responses.

• To enhance the security of the Lambda function.

Which button is used to add a trigger service to a Lambda function in the AWS Management Console?

• The 'API Gateway' button.

• The 'Trigger' button.

• The 'Configure Trigger' button.

• The 'Add Service' button.

What is the result of hitting the API endpoint URL in a browser?

• It displays the API Gateway configuration.

• It triggers a security alert.

• It returns a 'Hello from Lambda' message.

• It opens the AWS Management Console.

What does the proxy definition in the API Gateway allow?

• It enables logging of all API requests.

• It allows any HTTP method to invoke the Lambda function.

• It provides a graphical interface for API management.

• It restricts access to specific IP addresses.
