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.

Controlling access to buckets and objects on Amazon S3

Once the object is stored in the bucket, the next major step is to manage access. S3 is private by default, and access is given to other users or groups or resources via several methods. This means that access to the objects can be managed via Access Control Lists (ACLs), Public Access Settings, Identity Policies, and Bucket Policies.

Let's look at some of these in detail.

S3 bucket policy

S3 bucket policy is a resource policy that is attached to a bucket. Resource policies decide who can access that resource. It differs from identity policies in that identity policies can be attached or assigned to the identities inside an account, whereas resource policies can control identities from the same account or different accounts. Resource policies control anonymous principals too, which means an object can be made public through resource policies. The following sample policy allows everyone in the world to read the bucket...
