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.

Redshift architecture review and storage deep dive

In this section, we will take a deeper dive into the architecture of Redshift clusters, as well as into how data in tables is stored across Redshift nodes. This in-depth look will help you understand and fine-tune Redshift's performance, though we will also cover how many of the design decisions affecting table layout can be automated by Redshift.

In Chapter 2, Data Management Architectures for Analytics, we briefly discussed how the Redshift architecture uses leader and compute nodes. Each compute node contains a certain amount of compute power (CPUs and memory), as well as a certain amount of local storage. When configuring your Redshift cluster, you can add multiple compute nodes, depending on your compute and storage requirements. Note that to provide fault tolerance and improved durability, the compute nodes have 2.5 - 3x the stated node storage capacity (for example, if addressable storage capacity is listed as 2.56 TB...
