AWS Serverless Microservices with Patterns and Best Practices - Understanding Lambda Trigger with Event JSON Object

This video tutorial explains how to trigger AWS Lambda functions using event JSON objects, particularly from the API Gateway. It covers the process of setting up and testing Lambda functions using templates, specifically the 'Hello World' template. The tutorial also demonstrates how to modify Lambda code to handle incoming events and log them using CloudWatch. By the end, viewers will understand how to manage and test Lambda functions effectively.

What is the first step in modifying a Lambda function to handle incoming events?

• Deploying the function

• Logging incoming events

• Deleting the existing function

• Creating a new function

What is the significance of deploying changes to a Lambda function?

• It creates a backup of the function

• It deletes the function from AWS

• It updates the function with the latest code changes

• It saves the function to a local file

How can you verify that a Lambda function processes events correctly after modification?
