Learn Amazon SageMaker - Second Edition

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning models at scale without managing any infrastructure. It helps you focus on the machine learning problem at hand and deploy high-quality models by eliminating the heavy lifting typically involved in each step of the ML process. This second edition will help data scientists and ML developers to explore new features such as SageMaker Data Wrangler, Pipelines, Clarify, Feature Store, and much more. You'll start by learning how to use various capabilities of SageMaker as a single toolset to solve ML challenges and progress to cover features such as AutoML, built-in algorithms and frameworks, and writing your own code and algorithms to build ML models. The book will then show you how to integrate Amazon SageMaker with popular deep learning libraries, such as TensorFlow and PyTorch, to extend the capabilities of existing models. You'll also see how automating your workflows can help you get to production faster with minimum effort and at a lower cost. Finally, you'll explore SageMaker Debugger and SageMaker Model Monitor to detect quality issues in training and production. By the end of this Amazon book, you'll be able to use Amazon SageMaker on the full spectrum of ML workflows, from experimentation, training, and monitoring to scaling, deployment, and automation.

Chapter 11: Deploying Machine Learning Models

In previous chapters, we've deployed models in the simplest way possible: by configuring an estimator, calling the fit() application programming interface (API) to train the model, and calling the deploy() API to create a real-time endpoint. This is the simplest scenario for development and testing, but it's not the only one.

Models can be imported. For example, you could take an existing model that you trained on your local machine, import it into SageMaker, and deploy it as if you had trained it on SageMaker.

In addition, models can be deployed in different configurations, as follows:

  • A single model on a real-time endpoint, which is what we've done so far, as well as several model variants in the same endpoint.
  • A sequence of up to five models, called an inference pipeline.
  • An arbitrary number of related models that are loaded on demand on the same endpoint, known as a multi-model endpoint. We&apos...
