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

The video tutorial covers the creation and configuration of AWS Lambda functions using the AWS CDK, with a focus on Node.js. It explains the benefits of using Node.js for Lambda functions, such as automatic bundling and packaging. The tutorial also details the steps to implement and configure Node.js Lambda functions, including setting environment variables and specifying runtime. Additionally, it discusses granting permissions for DynamoDB operations, emphasizing the power of AWS CDK in simplifying these processes.

What is the primary purpose of using AWS CDK in the context of Lambda functions?

• To develop mobile applications

• To replace AWS Management Console

• To automate the creation of infrastructure

• To manually configure AWS services

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

• AWS CLI

• AWS SDK

• Node.js Core

• Amazon Lambda Node.js Library

What is a key feature of the Node.js Lambda function library?

• Manual code deployment

• Automatic bundling and packaging

• Reduced execution time

• Increased memory usage

What is the purpose of using a monorepo structure in project architecture?

• To reduce the number of developers needed

• To separate each microservice into different repositories

• To manage multiple microservices in a single repository

• To increase the complexity of the project

How are environment variables used in Node.js Lambda functions?

• To reduce code size

• To increase security

• To execute functions faster

• To store runtime configurations

What is the significance of specifying the runtime explicitly in Node.js Lambda functions?

• To specify the exact Node.js version used

• To ensure compatibility with the latest Node.js version

• To reduce the function's execution time

• To increase the function's memory allocation

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

• To specify the function's memory allocation

• To define the path to the function's implementation

• To reduce the function's code size

• To increase the function's execution speed

Why is it important to grant permissions to Lambda functions for DynamoDB operations?

• To increase the function's execution speed

• To reduce the function's memory usage

• To enable the function to perform CRUD operations on DynamoDB

• To allow the function to access external APIs

What is the advantage of using AWS CDK for granting permissions?

• It requires manual configuration

• It simplifies the process with predefined functions

• It increases the security of the function

• It reduces the function's execution time

How does the Node.js Lambda function library enhance microservices development?

• By increasing the function's execution time

• By requiring manual configuration

• By providing preconfigured options for Node.js

• By reducing the function's memory usage
