AWS Serverless Microservices with Patterns and Best Practices - Implement Lambda Function Code for Ordering Microservice

The video tutorial guides viewers through setting up an ordering microservice using Node.js and AWS Lambda. It begins with an overview of the ordering microservices and the creation of a Node.js application. The tutorial then demonstrates the basic implementation of a Lambda function, including setting up a minimal handle method. Finally, the focus shifts to infrastructure development using AWS CDK, highlighting the creation of a DynamoDB table and an API Gateway.

What is the purpose of the entry property in the ordering Lambda function?

• To set the timeout duration

• To define the memory allocation

• To point to the index of the Lambda function

• To specify the runtime environment

Why is the index.js file created in the ordering folder?

• To store configuration settings

• To handle API requests

• To implement the Node.js Lambda function code

• To manage database connections

What is the initial implementation of the handle method in the ordering Lambda function?

• It interacts with the DynamoDB table

• It logs the request details

• It returns a 404 error

• It returns a message with a 200 status code

Which AWS service is used for infrastructure development in this tutorial?

• AWS OpsWorks

• AWS Elastic Beanstalk

• AWS CDK

• AWS CloudFormation

What components are created as part of the infrastructure development?

• Elastic Load Balancer and Auto Scaling Group

• DynamoDB table and API Gateway

• RDS database and VPC

• S3 bucket and EC2 instance
