Run Machine Learning Training with Managed Spot Training for Amazon SageMaker

Lab Details

  1. This lab walks you through the steps to create a Sagemaker notebook instance. You will use JupyterLab for running the training job and find the difference.

  2. Duration: 90 minutes

  3. AWS Region: US East (N. Virginia) us-east-1

Introduction

What is Amazon SageMaker

  • It is a fully managed machine learning service.

  • Amazon SageMaker helps developers and data scientists to build and train machine learning (ML) models so they can be deployed quickly on a production-ready hosted environment.

  • It removes the heavy lifting from steps of the ML process to make it easy for developing high-quality models.

  • Since it is a fully managed service, there are no maintenance windows or scheduled downtimes.

  • It stores the code in ML storage volumes which are secured by security groups and encrypted at rest.

  • It does not use or share customer models with other customers' training data and algorithms.  

What is EC2 Spot Instance

  • Spot Instances are an unused part of Amazon EC2, using which you can save up to 90% on cost as compared to On-Demand cost, but AWS can interrupt your spot instances if the Current Price is higher than the Maximum Price you specified.

  • Spot uses the same EC2 instances (AMI and instance type) what On-Demand and Reserved Instances use. It is the best to fit for use cases where data is reproducible and can sustain the interruption at any point in time.

  • You can use Spot Instance as additional compute capacity to your On-Demand or Reserved Instances, where fault-tolerant is acceptable.

  • EC2 Spot Instances can be launched the same way you launch EC2 Instance, like using Spot Fleet. Auto Scaling Groups or AWS Management Console.

  • If AWS terminates or stops your Amazon EC2 Spot Instance within an hour then you will not be charged.

  • However, if you choose to stop or terminate your newly launched Spot Instances by yourself, you will have to pay for the total number of seconds you have used.
