Amazon SageMaker is a fully managed service that enables developers and data scientists to quickly and easily build, train, and deploy machine learning (ML) models at any scale. Typically, you can use the pre-built and optimized training and inference containers that have been optimized for AWS hardware. Although those containers cover many deep learning workloads, you may have use cases where you want to use a different framework or otherwise customize the contents of your OS libraries within the container. To accommodate this, SageMaker provides the flexibility to train models using any framework that can run in a Docker container. This functionality enables you to use existing SageMaker training capabilities such as training jobs, hyperparameter tuning, and Managed Spot Training.

Effective October 1st, 2020, we're reducing the prices for ml.p3 and ml.p2 instances in Amazon SageMaker by up to 18% so you can maximize your machine learning (ML) budgets and innovate with deep learning using these accelerated compute instances. The new price reductions apply to ml.p3 and ml.p2 instances of all sizes for Amazon SageMaker Studio notebooks, on-demand notebooks, processing, training, real-time inference, and batch transform. Customers including Intuit, Thomson Reuters, Cerner, and Zalando are already reducing their total cost of ownership (TCO) by at least 50% using Amazon SageMaker. Amazon SageMaker removes the heavy lifting from each step of the ML process and makes it easy to apply advanced deep learning techniques at scale. Amazon SageMaker provides lower TCO because it's a fully managed service, so you don't need to build, manage, or maintain any infrastructure and tooling for your ML workloads.

XGBoost is a popular and efficient machine learning (ML) algorithm for regression and classification tasks on tabular datasets. It implements a technique known as gradient boosting on trees and performs remarkably well in ML competitions. Since its launch, Amazon SageMaker has supported XGBoost as a built-in managed algorithm. For more information, see Simplify machine learning with XGBoost and Amazon SageMaker. As of this writing, you can take advantage of the open-source Amazon SageMaker XGBoost container, which has improved flexibility, scalability, extensibility, and Managed Spot Training.

Amazon SageMaker manages Spot instances on your behalf, so you don't have to poll continuously for capacity. There is no need to build additional tooling as Amazon SageMaker enables your training jobs to run reliably as and when Spot capacity becomes available. Managed Spot Training can be used when training models built using the popular ML frameworks in SageMaker, SageMaker built-in algorithms, and custom built models. You can also use Managed Spot Training Automatic Model Tuning to tune your machine learning models.

Amazon SageMaker is a fully-managed, modular machine learning (ML) service that enables developers and data scientists to easily build, train, and deploy models at any scale. With a choice of using built-in algorithms, bringing your own, or choosing from algorithms available in AWS Marketplace, it's never been easier and faster to get ML models from experimentation to scale-out production. One of the key benefits of Amazon SageMaker is that it frees you of any infrastructure management, no matter the scale you're working at. For instance, instead of having to set up and manage complex training clusters, you simply tell Amazon SageMaker which Amazon Elastic Compute Cloud (EC2) instance type to use, and how many you need: the appropriate instances are then created on-demand, configured, and terminated automatically once the training job is complete. As customers have quickly understood, this means that they will never pay for idle training instances, a simple way to keep costs under control.
