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.

Deploying a multi-model endpoint

Multi-model endpoints are useful when you're dealing with a large number of models where it wouldn't make sense to deploy to individual endpoints. For example, imagine a SaaS company building a regression model for each one of their 10,000 customers. Surely, they wouldn't want to manage (and pay for) 10,000 endpoints!

Understanding multi-model endpoints

A multi-model endpoint can serve CPU-based predictions from an arbitrary number of models stored in S3 (GPUs are not supported at the time of writing). The path of the model artifact to use is passed in each prediction request. Models are loaded and unloaded dynamically, according to usage and the amount of memory available on the endpoint. Models can also be added to, or removed from, the endpoint by simply copying or deleting artifacts in S3.

In order to serve multiple models, your inference container must implement a specific set of APIs that the endpoint will invoke: LOAD...
