Learn Amazon SageMaker

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning (ML) models at scale, without managing any infrastructure. It helps you focus on the ML problem at hand and deploy high-quality models by removing the heavy lifting typically involved in each step of the ML process. This book is a comprehensive guide for data scientists and ML developers who want to learn the ins and outs of Amazon SageMaker. You’ll understand how to use various modules of SageMaker as a single toolset to solve the challenges faced in ML. As you progress, you’ll cover features such as AutoML, built-in algorithms and frameworks, and the option for writing your own code and algorithms to build ML models. Later, the book will show you how to integrate Amazon SageMaker with popular deep learning libraries such as TensorFlow and PyTorch to increase the capabilities of existing models. You’ll also learn to get the models to production faster with minimum effort and at a lower cost. Finally, you’ll explore how to use Amazon SageMaker Debugger to analyze, detect, and highlight problems to understand the current model state and improve model accuracy. 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 13: Optimizing Prediction Cost and Performance

In the previous chapter, you learned how to automate training and deployment workflows.

In this final chapter, we'll focus on optimizing cost and performance for prediction infrastructure, which typically accounts for 90% of the machine learning spend by AWS customers. This number may come as a surprise, until we realize that the model built by a single training job may end on multiple endpoints running 24/7 at large scale.

Hence, great care must be taken to optimize your prediction infrastructure so as to ensure that you get the most bang for your buck!

This chapter has the following topics:

  • Autoscaling an endpoint
  • Deploying a multi-model endpoint
  • Deploying a model with Amazon Elastic Inference
  • Compiling models with Amazon SageMaker Neo
