AWS Serverless Microservices with Patterns and Best Practices - Creating API Gateway for Basket Microservices with AWS C

The video tutorial covers the creation of basket microservices using AWS CDK, focusing on setting up API Gateway infrastructure. It explains the differences between REST and HTTP APIs, and demonstrates how to design and implement API methods for basket microservices. The tutorial also includes a detailed walkthrough of developing and testing the basket API gateway, emphasizing the use of AWS Lambda and best practices like the open-closed principle.

What are the two types of API Gateway mentioned in the tutorial?

• SOAP API and HTTP API

• REST API and HTTP API

• REST API and SOAP API

• GraphQL API and REST API

Which AWS service is used to define and manage APIs in the tutorial?

• AWS Lambda

• AWS CloudFormation

• AWS CDK

• AWS S3

What is a key feature of Amazon API Gateway?

• It only integrates with AWS Lambda.

• It only supports REST APIs.

• It is a fully managed service for publishing, maintaining, and securing APIs.

• It requires manual scaling.

What is the purpose of the checkout method in the basket microservices?

• To delete a basket

• To update basket items

• To perform an asynchronous flow for basket checkout

• To create a new basket

What is the significance of the 'proxy' setting in the Lambda Rest API construct?

• It allows all requests to be directed to a single Lambda function.

• It enables automatic scaling of APIs.

• It is used to define API models explicitly.

• It is required for HTTP API integration.

What is the purpose of defining root and resource names in API design?

• To ensure API security

• To organize and structure API endpoints

• To increase API speed

• To reduce API costs

What is the first step in refactoring the API Gateway code?

• Adding new resources

• Deleting old methods

• Extracting methods for product and basket APIs

• Creating a new API Gateway

Which principle is followed to ensure the code is ready for extensions?

• Interface Segregation Principle

• Single Responsibility Principle

• Dependency Inversion Principle

• Open-Closed Principle

What is the role of the Lambda Rest API construct in the tutorial?

• It provides a graphical interface for API management.

• It is used for creating SOAP APIs.

• It integrates APIs with AWS Lambda functions.

• It is used for managing API keys.

What is the main advantage of using AWS CDK for API Gateway?

• It is cheaper than other AWS services.

• It requires no coding.

• It only supports REST APIs.

• It allows for infrastructure as code, making it easier to manage and deploy.
