6SageMaker Ecosystem and AI Services

• 6.1The SageMaker Workflow

  A unified ML platform—understand SageMaker Studio, built-in algorithms, training jobs, Processing, and the prepare → train → deploy → monitor flow.

• 6.2High-Level AI Services

  Use without building—understand Rekognition, Comprehend, Transcribe/Polly, Translate, Textract, and Personalize (the time-series Forecast service is closed to new use; its successor is SageMaker Canvas, etc.). Implement quickly via no-training APIs.

• 6.3Data Labeling and Build Strategy

  The final call—understand Ground Truth (labeling), AI services vs custom, the cost/effort trade-off, and choosing wisely. Decide build vs buy smartly.
