MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
A company wants to deploy 50 small models (each ~100 MB) for real-time inference. They need to minimize hosting costs while maintaining low latency. Which SageMaker hosting option is most cost-effective?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SageMaker Multi-Model Endpoint (MME)
Multi-Model Endpoint (MME) allows hosting multiple models on the same instance, sharing resources. Since the models are small, MME is cost-effective. Real-time endpoints would require separate instances. Serverless is for on-demand but may incur cold starts. Asynchronous is for batch-like workloads.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SageMaker Serverless Inference
Why it's wrong here
Serverless can be cost-effective for variable traffic but may have cold starts and is not optimized for many small models.
- ✗
SageMaker Asynchronous Inference
Why it's wrong here
Asynchronous is not for real-time inference.
- ✓
SageMaker Multi-Model Endpoint (MME)
Why this is correct
MME allows multiple models to share a single instance, reducing cost.
- ✗
SageMaker real-time endpoint with one instance per model
Why it's wrong here
This is not cost-effective for 50 small models.
