A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

3-7Cloud Technology and ServicesModerate

An application must detect objects, scenes and faces in images and video that users upload. The team has no machine learning skills. Which service fits?

Amazon RekognitionCorrect · your answerCorrect. Computer vision over images and video through an API.
Amazon ComprehendComprehend reads text and returns sentiment, entities and key phrases. It has no view of pixels.
Amazon TextractTextract pulls text, forms and tables out of scanned documents, which is a narrower problem than scene analysis.
Amazon PollyPolly turns text into lifelike speech, so it produces audio rather than interpreting an image.

Correct.

Concept

Pre-trained AI services expose a task through an API, so a team consumes a model rather than producing one. That is the right trade whenever the problem is a common one and the differentiator is elsewhere.

Why A

This is the image and video analysis service, reached through a simple API over files in S3, and it needs no machine learning expertise to add computer vision to an application.
