Model Deployment in SageMaker

Once you train and approve a model for production, use SageMaker to deploy your model to an endpoint for real-time inference. SageMaker provides multiple inference options so that you can pick the option that best suits your workload. You also configure your endpoint by choosing the instance type and number of instances you need for optimal performance. For details about model deployment, see Deploy models for inference.

After you deploy your models to production, you might want to explore ways to further optimize model performance while maintaining availability of your current models. For example, you can set up a shadow test to try out a different model or model serving infrastructure before committing to the change. SageMaker deploys the new model, container, or instance in shadow mode and routes to it a copy of the inference requests in real time within the same endpoint. You can log the responses of the shadow variant for comparison. For details about shadow testing, see Shadow tests. If you decide to go ahead and change your model, deployment guardrails help you control the switch from the current model to a new one. You can select such methods as blue/green or canary testing of the traffic shifting process to maintain granular control during the update. For information about deployment guardrails, see Update models in production.
