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!

Ingesting Batch and Streaming Data

Having developed a high-level architecture for our data pipeline, we can now dive deep into the varied components of the architecture. We will start with data ingestion so that in the hands-on section of this chapter, we can ingest data and use that data for the hands-on activities in future chapters.

Data engineers are often faced with the challenge of the five Vs of data. These are the variety of data (the diverse types and formats of data); the volume of data (the size of the dataset); the velocity of the data (how quickly the data is generated and needs to be ingested); the veracity or validity of the data (the quality, completeness, and credibility of the data); and finally, the value of data (the value that the data can provide the business with).

In this chapter, we will look at several different types of data sources and examine the various tools available within AWS for ingesting data from these sources. We will also look at how...
