AWS Certified Machine Learning Specialty: MLS-C01 Certification Guide

By: Somanath Nanda, Weslley Moura

Overview of this book

The AWS Certified Machine Learning Specialty exam tests your competency to perform machine learning (ML) on AWS infrastructure. This book covers the entire exam syllabus using practical examples to help you with your real-world machine learning projects on AWS. Starting with an introduction to machine learning on AWS, you'll learn the fundamentals of machine learning and explore important AWS services for artificial intelligence (AI). You'll then see how to prepare data for machine learning and discover a wide variety of techniques for data manipulation and transformation for different types of variables. The book also shows you how to handle missing data and outliers and takes you through various machine learning tasks such as classification, regression, clustering, forecasting, anomaly detection, text mining, and image processing, along with the specific ML algorithms you need to know to pass the exam. Finally, you'll explore model evaluation, optimization, and deployment and get to grips with deploying models in a production environment and monitoring them. By the end of this book, you'll have gained knowledge of the key challenges in machine learning and the solutions that AWS has released for each of them, along with the tools, methods, and techniques commonly used in each domain of AWS ML.

Protecting data on Amazon S3

In this section, we will learn how to record every version of an object. Along with durability, Amazon provides several techniques to secure the data in S3. Some of those techniques involve enabling versioning and encrypting the objects.

Versioning helps you to roll back to a previous version if there is any problem with the current object during update, delete, or put operations.

Through encryption, you can control the access of an object. You need the appropriate key to read and write an object. We will also learn Multi Factor Authentication (MFA) for delete operations. Amazon also allows Cross-Region Replication (CRR) to maintain a copy of an object in another region, which can be used for data backup during any disaster, for further redundancy, or for the enhancement of data access speed in different regions.

Applying bucket versioning

Let's now understand how we can enable bucket versioning with the help of some hands-on examples...
