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.

Explain the purpose of the DynamoDB client module in the context of microservices.

What are the best practices for creating database connections in Lambda functions?

Describe the two main use cases implemented in the microservices architecture discussed.

How does the asynchronous invocation from Amazon Event Bridge work in the context of the checkout basket?

What steps are involved in processing incoming events in the Lambda function for ordering microservices?
