AWS Serverless Microservices with Patterns and Best Practices - Overview Product Lambda Microservice Developments

The video tutorial covers the development of microservices using AWS tools, focusing on infrastructure as code with AWS CDK and the creation of Lambda functions for CRUD operations. It explains the integration of AWS services like DynamoDB and API Gateway, and demonstrates best practices for efficient microservice development.

What is the primary focus of the initial section on microservice development?

• Creating user interfaces

• Setting up a local development environment

• Developing product Lambda microservices and CRUD operations

• Deploying applications to AWS

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

• AWS Elastic Beanstalk

• AWS OpsWorks

• AWS CDK

• AWS CloudFormation

What is the purpose of the Node.js Lambda function in the infrastructure setup?

• To monitor application performance

• To perform CRUD operations on DynamoDB

• To manage user authentication

• To handle file storage

What is the role of the API Gateway in the architecture?

• To manage network security

• To facilitate communication between clients and Lambda functions

• To provide a user interface

• To store data

How does the AWS CDK help in managing infrastructure?

• By offering pre-built templates

• By automating user authentication

• By allowing infrastructure to be defined as code

• By providing a graphical interface

What is the first step in developing Lambda microservices?

• Writing test cases

• Creating a user interface

• Configuring network settings

• Setting up a DynamoDB client

Why is it important to establish a DynamoDB client outside of the Lambda function?

• To reduce execution time and increase concurrent execution

• To enhance security

• To increase the packet size

• To simplify code maintenance

Which AWS SDK version is used for implementing CRUD operations in this tutorial?

• Version 1

• Version 2

• Version 3

• Version 4

What is the main method used in the Lambda function for handling requests?

• handleMethod

• executeCommand

• handleRequest

• processRequest

What is the best practice for sending commands to DynamoDB from a Lambda function?

• Using a third-party library

• Using the DynamoDB client send method

• Using direct database queries

• Using HTTP requests
