Service Comparison

Batch Transform vs Real-Time Inference

The inference pattern follows latency and traffic shape.

What They Have in Common

Each option can solve part of the scenario. The exam expects you to choose the one that satisfies the stated constraints with the right operational burden, security boundary, availability model, and cost behavior.

Key Differences

Option	Primary model	Best use
Batch transform	Offline scoring	Large scheduled jobs, no persistent endpoint
Real-time endpoint	Synchronous low-latency inference	User-facing predictions, steady or bursty live requests
Async inference	Large payload or longer inference	Queue-style inference without immediate response
