SageMaker Model Registry, SageMaker Serverless interference

This question requires selecting the appropriate Amazon SageMaker feature for two distinct steps in the AI model lifecycle. Let’s break down each step and evaluate the options:

Step 1: Managing different versions of the model

The goal here is to identify a SageMaker feature that supports version control and management of machine learning models. Let’s analyze the options:

SageMaker Clarify: This feature is used to detect bias in models and explain model predictions, helping with fairness and interpretability. It does not provide functionality for managing model versions.

SageMaker Model Registry: This is a centralized repository in Amazon SageMaker that allows users to catalog, manage, and track different versions of machine learning models. It supports model versioning, approval workflows, and deployment tracking, making it ideal for managing different versions of a model.

SageMaker Serverless Inference: This feature enables users to deploy models for inference without managing servers, automatically scaling based on demand. It is focused on inference (predictions), not on managing model versions.

Conclusion for Step 1: The SageMaker Model Registry is the correct choice for managing different versions of the model.

Exact Extract Reference: According to the AWS SageMaker documentation, “The SageMaker Model Registry allows you to catalog models for production, manage model versions, associate metadata, and manage approval status for deployment.” (Source: AWS SageMaker Documentation - Model Registry, https://docs.aws.amazon.com/sagemaker/latest/dg/model-registry.html).

Step 2: Using the current model to make predictions

The goal here is to identify a SageMaker feature that facilitates making predictions (inference) with a deployed model. Let’s evaluate the options:

SageMaker Clarify: As mentioned, this feature focuses on bias detection and explainability, not on performing inference or making predictions.

SageMaker Model Registry: While the Model Registry helps manage and catalog models, it is not used directly for making predictions. It can store models, but the actual inference process requires a deployment mechanism.

SageMaker Serverless Inference: This feature allows users to deploy models for inference without managing infrastructure. It automatically scales based on traffic and is specifically designed for making predictions in a cost-efficient, serverless manner.

Conclusion for Step 2: SageMaker Serverless Inference is the correct choice for using the current model to make predictions.

Exact Extract Reference: The AWS documentation states, “SageMaker Serverless Inference is a deployment option that allows you to deploy machine learning models for inference without configuring or managing servers. It automatically scales to handle inference requests, making it ideal for workloads with intermittent or unpredictable traffic.” (Source: AWS SageMaker Documentation - Serverless Inference, https://docs.aws.amazon.com/sagemaker/latest/dg/serverless-inference.html).

Why Not Use the Same Feature Twice?

The question specifies that each SageMaker feature or resource should be selected one time or not at all. Since SageMaker Model Registry is used for version management and SageMaker Serverless Inference is used for predictions, each feature is selected exactly once. SageMaker Clarify is not applicable to either step, so it is not selected at all, fulfilling the question’s requirements.
