AWS Serverless Microservices with Patterns and Best Practices - Developing Lambda Handler Code

The video tutorial covers the development of AWS Lambda handler code using AWS CDK. It emphasizes two main development areas: infrastructure development with AWS CDK and Lambda microservices development. The tutorial focuses on creating a simple Lambda function using Node.js, detailing the setup of the project directory and the implementation of the function logic. The importance of separating infrastructure and application code is highlighted, along with best practices for exporting handler methods for API Gateway integration.

What is the primary focus of the video tutorial?

• Creating a database schema

• Developing a mobile application

• Designing a user interface

• Developing AWS Lambda handler code

What are the two main development areas discussed in the video?

• Database and API Development

• Security and Performance Optimization

• Infrastructure and Microservices Development

• Frontend and Backend Development

Which language is used for developing the infrastructure with AWS CDK?

• Python

• TypeScript

• Ruby

• Java

What is the runtime environment for the Lambda function being developed?

• Go

• Java

• Node.js

• Python

What is the purpose of exporting the handler method in a Lambda function?

• To enable asynchronous execution

• To allow the function to be triggered by API Gateway

• To improve performance

• To reduce code size

What HTTP status code is returned by the Lambda function in the example?

• 404

• 500

• 200

• 301

Why is it important for the Lambda function to return a response with status code and body?

• To ensure the function runs faster

• To enable logging of the response

• To allow API Gateway to return the correct response to the client

• To reduce the cost of execution
