Question

A gaming company planned to launch their new gaming application that will be in both web and mobile platforms. The company considers using GraphQL API to securely query or update data through a single endpoint from multiple databases, microservices, and several other API endpoints. They also want some portions of the data to be updated and accessed in real-time.

The customer prefers to build this new application mostly on serverless components of AWS.

As a Solutions Architect, which of the following AWS services would you recommend the customer to develop their GraphQL API?

A. Kinesis Data Firehose

B. Amazon Neptune

C. Amazon API Gateway

D. AWS AppSync

Answer 1

D. AWS AppSync

Explanation

Option A is incorrect because Amazon Kinesis Data Firehose is a fully managed service for delivering real-time streaming data to destinations such as Amazon S3, Amazon Redshift, Amazon OpenSearch, etc. It cannot create GraphQL API.

Option B is incorrect. Amazon Neptune is a fast, reliable, fully managed graph database service that makes it easy to build and run applications. It is a database and cannot be used to create GraphQL API.

Option C is incorrect because Amazon API Gateway supports RESTful APIs (HTTP and REST API) and WebSocket APIs. It is not meant for the development of GraphQL API.

Option D is CORRECT because with AWS AppSync one can create serverless GraphQL APIs that simplify application development by providing a single endpoint to securely query or update data from multiple data sources and leverage GraphQL to implement engaging real-time application experiences.
