AWS Serverless Microservices with Patterns and Best Practices - Developing Ordering Lambda Microservice with DynamoDB Cl

The video tutorial covers the development of microservices using the DynamoDB client SDK. It begins with setting up a NodeJS module for the DynamoDB client, emphasizing best practices for connection management in AWS Lambda functions. The tutorial then moves on to business code development, focusing on implementing use cases for microservices, such as handling checkout basket events and retrieving orders. The video concludes with a discussion on processing both synchronous and asynchronous events in Lambda functions.

What is the primary reason for creating a separate Node.js module for the DynamoDB client?

• To handle connection management efficiently for Lambda executions

• To increase the complexity of the code

• To make the code less readable

• To ensure the client is only used for synchronous operations

Which service is used for asynchronous invocation in the checkout basket event use case?

• Amazon SNS

• Amazon SQS

• Amazon EventBridge

• Amazon S3

What is the purpose of the synchronous invocation in the ordering microservices?

• To retrieve all orders and orders by username

• To delete user accounts

• To update product inventory

• To process checkout basket events

What is the next step after logging the incoming event in the ordering microservices development?

• To delete the event

• To perform the use case operations

• To ignore the event

• To send the event to another service

What is the main focus of the next video in the series?

• Implementing a new API Gateway

• Developing a new database

• Creating a switch statement and methods for ordering microservices

• Designing a user interface
