AWS Serverless Microservices with Patterns and Best Practices - Creating Lambda Function for Basket Microservices with A

The video tutorial covers the creation of AWS Lambda functions using AWS CDK, focusing on Node.js microservices. It begins with an introduction to AWS CDK and Lambda, followed by an exploration of AWS Lambda libraries. The tutorial then delves into the specifics of Node.js Lambda functions, highlighting their advantages. The project setup and code refactoring for microservices are demonstrated, leading to the creation of product and basket functions. The tutorial concludes with the finalization of basket microservices, emphasizing the use of Node.js functions for efficient Lambda packaging.

What is the primary purpose of using AWS CDK version two API reference?

• To find construct libraries for AWS resources

• To monitor AWS services

• To deploy AWS resources directly

• To manage AWS billing

Which library is used for creating Node.js Lambda functions in AWS CDK?

• AWS SDK for JavaScript

• AWS Lambda node JS library

• AWS Lambda Construct library

• AWS CDK Core library

What is a key benefit of using the Node.js function construct?

• It creates larger Lambda packages

• It simplifies the deployment process

• It increases the runtime of Lambda functions

• It results in smaller Lambda packages

What does the Node.js function construct automatically handle?

• Bundling and packaging of external modules

• User authentication

• Database connections

• Network configurations

What is the purpose of using extract methods in the project structure?

• To add more features

• To simplify and organize code

• To increase code complexity

• To remove unnecessary code

What is the role of the 'entry' property in Node.js function props?

• To specify the runtime environment

• To define the entry point of the function

• To configure logging

• To set environment variables

What is the first step in creating a basket microservices Lambda function?

• Granting permissions

• Deploying the function

• Creating the function method

• Setting environment variables

Why is it important to grant permissions to the basket Lambda function?

• To access basket data from DynamoDB

• To enable logging

• To allow access to external APIs

• To increase function runtime

What is the significance of the 'grant read, write data' permission?

• It allows the function to modify its own code

• It provides access to AWS billing information

• It allows the function to access external APIs

• It enables the function to read and write data to DynamoDB

What is the purpose of setting environment variables in Lambda functions?

• To manage function dependencies

• To define runtime settings

• To store sensitive information securely

• To configure the AWS region
