AWS Serverless Microservices with Patterns and Best Practices - Developing Product Lambda Microservice with DynamoDB Cli

The video tutorial covers the use of the DynamoDB Client SDK in microservices, focusing on handling incoming events from Amazon API Gateway. It explains the importance of using switch statements for different HTTP methods and how to handle path parameters for interacting with DynamoDB. The tutorial also verifies infrastructure code using CDK and outlines the next steps for implementing get methods with AWS SDK libraries.

What is the primary purpose of using a switch statement in the context of handling HTTP methods?

• To simplify the code structure

• To handle multiple HTTP methods efficiently

• To improve the performance of the API

• To reduce the number of lines of code

How does the system differentiate between a request for a single product and a request for all products?

• By checking the HTTP method type

• By using a different API endpoint

• By analyzing the request headers

• By examining the presence of path parameters

What role do path parameters play in the API Gateway setup?

• They specify the resource to be accessed

• They define the HTTP method to be used

• They determine the response format

• They are used to authenticate the request

Why is it important to verify the infrastructure code?

• To ensure it matches the implementation

• To reduce the cost of deployment

• To improve the speed of the API

• To simplify the codebase

What is the significance of the 'get product by ID' method in the API Gateway?

• It helps in deleting a product from the database

• It is used for updating product information

• It enables retrieving a specific product using its ID

• It allows fetching all products at once

What is the next step after setting up the structure for handling incoming events?

• Optimizing the code for better performance

• Deploying the microservices to production

• Testing the API Gateway setup

• Implementing the actual methods to interact with DynamoDB

Which AWS service is used to interact with the database in this setup?

• Amazon S3

• Amazon RDS

• Amazon DynamoDB

• Amazon Redshift
