AWS Serverless Microservices with Patterns and Best Practices - Developing AWS Lambda Synchronous Microservices with Ama

This video tutorial guides viewers through building synchronous microservices using AWS Lambda and API Gateway. It covers creating a Lambda function, setting up an API Gateway, configuring HTTP methods, and deploying and testing the API. The tutorial emphasizes using Node.js for Lambda functions and demonstrates the integration of Lambda with API Gateway for handling requests and responses.

What is the primary focus of the video tutorial?

• Creating microservices with AWS Lambda for synchronous APIs

• Developing mobile applications using AWS

• Setting up databases with AWS RDS

• Building asynchronous APIs with AWS Lambda

What is the first step in creating a Lambda function?

• Choosing a runtime environment

• Deploying the API

• Configuring CloudWatch logs

• Setting up API Gateway

Which runtime is used for the Lambda function in this tutorial?

• Node.js

• Java

• Ruby

• Python

What type of API is created in the API Gateway?

• SOAP API

• GraphQL API

• REST API

• WebSocket API

Why is Lambda proxy integration used in the API Gateway setup?

• To enable WebSocket communication

• To handle SOAP requests

• To proxy requests to the Lambda function with request details

• To automatically scale the API Gateway

What is the purpose of deploying the API?

• To enable monitoring with CloudWatch

• To set up a database connection

• To make the API accessible to clients

• To configure the Lambda function

What response is expected when the API is successfully invoked?

• 500 Internal Server Error

• 200 Success with 'Hello from Lambda'

• 301 Moved Permanently

• 404 Not Found

How can you verify the API's performance and invocations?

• By checking the AWS Lambda console

• By using CloudWatch logs

• By deploying the API again

• By setting up a new API Gateway

What tool is used to monitor the Lambda function invocations?

• AWS CloudWatch

• AWS EC2

• AWS RDS

• AWS S3

What does the CloudWatch log indicate about the API invocations?

• The API is not integrated with Lambda

• The API was invoked twice successfully

• The API returned errors

• The API was never invoked
