Which service is an open source, distributed search and analytics suite derived from Elasticsearch?

• A. Amazon OpenSearch Service
• B. Amazon QuickSight
• C. Amazon AppFlow
• D. AWS AppSync

Answer: (A)

OpenSearch is an open-source, distributed search and analytics suite that originated as a fork of Elasticsearch. AWS offers a managed service for this stack called Amazon OpenSearch Service, which lets you deploy, scale, and secure OpenSearch clusters without managing the underlying infrastructure. This matches the description in the question: an open-source, distributed search and analytics platform derived from Elasticsearch is OpenSearch, and the corresponding AWS service is Amazon OpenSearch Service. The other options serve different purposes — QuickSight for business intelligence, AppFlow for data transfer, and AppSync for GraphQL APIs — and are not described as an open-source search and analytics suite derived from Elasticsearch.
