Data Engineering with AWS

By: Gareth Eagar

Overview of this book

Written by a Senior Data Architect with over twenty-five years of experience in the business, Data Engineering for AWS is a book whose sole aim is to make you proficient in using the AWS ecosystem. Using a thorough and hands-on approach to data, this book will give aspiring and new data engineers a solid theoretical and practical foundation to succeed with AWS. As you progress, you’ll be taken through the services and the skills you need to architect and implement data pipelines on AWS. You'll begin by reviewing important data engineering concepts and some of the core AWS services that form a part of the data engineer's toolkit. You'll then architect a data pipeline, review raw data sources, transform the data, and learn how the transformed data is used by various data consumers. You’ll also learn about populating data marts and data warehouses along with how a data lakehouse fits into the picture. Later, you'll be introduced to AWS tools for analyzing data, including those for ad-hoc SQL queries and creating visualizations. In the final chapters, you'll understand how the power of machine learning and artificial intelligence can be used to draw new insights from data. By the end of this AWS book, you'll be able to carry out data engineering tasks and implement a data pipeline on AWS independently.

Hands-on – creating data transformations with AWS Glue DataBrew

In Chapter 7, Transforming Data to Optimize for Analytics, we used AWS Glue Studio to create a data transformation job that took in multiple sources to create a new table. In this chapter, we discussed how AWS Glue DataBrew is a popular service for data analysts, so we'll now make use of Glue DataBrew to transform a dataset.

Differences between AWS Glue Studio and AWS Glue DataBrew

Both AWS Glue Studio and AWS Glue DataBrew provide a visual interface for designing transformations, and in many use cases either tool could be used to achieve the same outcome. However, Glue Studio generates Spark code that can be further refined in a code editor and can be run in any compatible environment. Glue DataBrew does not generate code that can be further refined, and Glue DataBrew jobs can only be run within the Glue DataBrew service. Glue Studio has fewer built-in transforms, and the transforms it does include are...
