Chapter 3 is where the real AWS content starts. This is the overview of analytics services you need to know for the DEA-C01 exam. Even if you’re not taking the exam, it’s a solid map of what AWS offers for data work.

There are a lot of services here. Some overlap. Some feel redundant. That’s just how AWS works.

Previous: Part II, Chapter 6 - Miracle Metal

This is the chapter where Rand drops the bomb. Everything the looters have been building toward – all those incremental regulations and emergency powers and “temporary” measures – reaches its logical conclusion. Worse than anything you could have predicted.

Directive 10-289

Wesley Mouch reads it aloud in a room full of bureaucrats and cronies. Eight points. Each one more insane than the last. Every engineer and every person who has ever changed jobs needs to hear this:

Chapter 2 is called “Prerequisite Knowledge for Aspiring Data Engineers.” It covers the foundation you need before touching any AWS service. Databases, big data concepts, processing frameworks, data lakes, warehouses, ETL patterns, CI/CD, and AWS basics.

If you already work in tech, a lot of this will feel like a refresher. It’s nice to have it all in one place though. Some of these topics honestly deserve more attention than people give them during cert prep.

Previous: Part II, Chapter 5 - Account Overdrawn

This chapter made me angry. Not the abstract, big-picture anger Rand usually stirs up. More personal than that. It hit close to work I do every day.

The Directive

Wesley Mouch and his crew of bureaucrats, industrialists, and union bosses are gathered in Washington. They are drafting Directive 10-289 – basically the government’s answer to an economy that is falling off a cliff. Their solution? Freeze everything. Nobody quits their job. Nobody closes their business. Nobody invents anything new. All patents and copyrights get handed over to the state as “voluntary” Gift Certificates.

Chapter 1 is the warm-up. No heavy AWS services yet. It sets the stage: what the exam looks like, what topics it covers, and how to approach the questions. If you already know the exam structure, you can skim this. There are a few useful bits here worth your time though.
