Topic 1 Question 468
A company is developing a microservices application that will provide a search catalog for customers. The company must use REST APIs to present the frontend of the application to users. The REST APIs must access the backend services that the company hosts in containers in private VPC subnets.
Which solution will meet these requirements?
Design a WebSocket API by using Amazon API Gateway. Host the application in Amazon Elastic Container Service (Amazon ECS) in a private subnet. Create a private VPC link for API Gateway to access Amazon ECS.

- 正解だと思う選択肢: B
REST API with Amazon API Gateway: REST APIs are the appropriate choice for providing the frontend of the microservices application. Amazon API Gateway allows you to design, deploy, and manage REST APIs at scale.
Amazon ECS in a Private Subnet: Hosting the application in Amazon ECS in a private subnet ensures that the containers are securely deployed within the VPC and not directly exposed to the public internet.
Private VPC Link: To enable the REST API in API Gateway to access the backend services hosted in Amazon ECS, you can create a private VPC link. This establishes a private network connection between the API Gateway and ECS containers, allowing secure communication without traversing the public internet.
