Question

A software-as-a-service (SaaS) company needs to implement customer file uploads. Industry standards require the company to provide OpenAPI specifications to customers. The company will use Amazon S3 for file storage. Which solution meets these requirements in the MOST cost-effective way?

Accepted Answer

B. Create an Amazon API Gateway REST API. Set up an AWS service integration for the upload. Create mapping templates to transform the requests and responses to match AWS API requirements. Export the OpenAPI definition.

Answer

Create an Application Load Balancer. Create an Amazon Elastic Container Service (Amazon ECS) cluster for the application to process uploads to Amazon S3. Generate the OpenAPI definitions separately.

Answer

Create an AWS Verified Access instance. Deploy an Amazon EC2 instance with the application to process uploads. Connect the instance as a network interface endpoint. Generate the OpenAPI definitions separately.

Answer

Create an Amazon CloudFront distribution. Create a Lambda@Edge function as an authorizer. Configure the S3 bucket for the uploads. Write an AWS Lambda function to periodically export the OpenAPI definition from CloudFront.
