AWS Serverless Microservices with Patterns and Best Practices - AWS API Gateway Trigger AWS Lambda with API Gateway Prox

The video tutorial explains how AWS API Gateway triggers Lambda functions using event JSON objects. It covers the importance of understanding the event structure, methods to find event JSON objects, and accessing event attributes in Lambda functions. The tutorial also discusses the response format and implementation, error handling, and using AWS Management Console to explore event structures. Finally, it prepares viewers for the next video on developing a product microservice with CRUD operations.

What is the primary role of API Gateway in relation to AWS Lambda?

• To manage user authentication

• To provide data analytics

• To trigger Lambda functions

• To store data

Which method is suggested for finding the event JSON object that triggers a Lambda function?

• Using AWS CLI

• Searching on Google

• Reading AWS whitepapers

• Contacting AWS support

What does the event JSON object from API Gateway typically include?

• Server configurations

• User credentials

• HTTP method and parameters

• Database connection strings

How can you access attributes of the event JSON object in a Lambda function?

• Using SQL queries

• Through dot notation

• By calling AWS support

• Using a third-party library

What must be included in the response from a Lambda function to API Gateway?

• A status code and body

• User authentication token

• Database schema

• Server IP address

Why is it important to return a status code and body in the Lambda response?

• To improve data storage

• To increase data security

• To reduce server load

• To ensure API Gateway can return a response to the client

What is one way to find the structure of a Lambda execution event object?

• Using AWS Management Console

• Using third-party tools

• Attending AWS webinars

Which AWS service can trigger a Lambda function asynchronously?

• Amazon S3

• Amazon RDS

• Amazon EC2

• Amazon EventBridge

What is the purpose of using test events in AWS Management Console?

• To manage user access

• To simulate incoming events for Lambda functions

• To monitor network traffic

• To configure server settings

What is a key characteristic of AWS Lambda?

• It is used for data storage

• It requires manual scaling

• It is event-driven

• It is a server-based service
