Amazon Sagemaker is a cloud machine-learning platform that enables developers to create, train, and deploy machine-learning (ML) models in the cloud. SageMaker also enables developers to deploy ML models on embedded systems and edge-devices.

SageMaker provides an integrated Jupyter authoring notebook instance to access to data sources for exploration and analysis. It also provides common machine learning algorithms optimized to run efficiently against extremely large data in a distributed environment.
