Overview of this book

This book, authored by a seasoned Senior Data Architect with 25 years of experience, aims to help you achieve proficiency in using the AWS ecosystem for data engineering. This revised edition provides updates in every chapter to cover the latest AWS services and features, takes a refreshed look at data governance, and includes a brand-new section on building modern data platforms which covers; implementing a data mesh approach, open-table formats (such as Apache Iceberg), and using DataOps for automation and observability. You'll begin by reviewing the key concepts and essential AWS tools in a data engineer's toolkit and getting acquainted with modern data management approaches. You'll then architect a data pipeline, review raw data sources, transform the data, and learn how that transformed data is used by various data consumers. You’ll learn how to ensure strong data governance, and about populating data marts and data warehouses along with how a data lakehouse fits into the picture. After that, you'll be introduced to AWS tools for analyzing data, including those for ad-hoc SQL queries and creating visualizations. Then, you'll explore how the power of machine learning and artificial intelligence can be used to draw new insights from data. In the final chapters, you'll discover transactional data lakes, data meshes, and how to build a cutting-edge data platform on AWS. By the end of this AWS book, you'll be able to execute data engineering tasks and implement a data pipeline on AWS like a pro!

Common data preparation transformations

The first set of transformations that we look at are those that help prepare the data for further transformations later in the pipeline. These transformations are designed to apply relatively generic optimizations to individual datasets that we are ingesting into the data lake. For these optimizations, you may need some understanding of the source data system and context, but, generally, you do not need to understand the ultimate business use case for the dataset.

Protecting PII data

Often, datasets that we ingest may contain personally identifiable information (PII) data, and there may be governance restrictions on which PII data can be stored in the data lake. As a result, we need to have a process that protects the PII data as soon as possible after it is ingested.

There are a number of common approaches that can be used here (such as tokenization or hashing), each with its own advantages and disadvantages, as we discussed in...
