Well, let me tell you a secret: Developers are obsessed with data engineering because they love to spend countless hours cleaning up messy data, writing complicated ETL pipelines, and trying to figure out why their code is failing in production.

It’s like a puzzle that they can’t resist solving, even if it means staying up all night with nothing but a cup of coffee and a stack of error logs to keep them company. And let’s not forget the sheer thrill of finally getting that data to flow smoothly from one system to another.

But in all seriousness, data engineering is becoming increasingly important in today’s data-driven world. Developers who have a solid foundation in data engineering can create efficient and effective data pipelines that can provide valuable insights to businesses. Plus, it’s just really satisfying to see all that data flowing smoothly and accurately through your pipeline.

Before we go into more detail, I would appreciate it if you could review the prior article, as it will provide you with some background information to the entire DE Roadmap journey.

Data Engineering — Basic Introduction

Data engineers are in a unique position. They need to understand the basics of data engineering and be able to build their own solutions. This is because they work with data, which is often not easy to come by. In this post, I will explain why learning the basics of anything makes more sense, and then I will go into how understanding virtualization, containerization, and Docker architecture can help data analysts in their work.

Data engineering is a field that has its own jargon. It can be hard to understand when you’re just starting out, but it doesn’t have to be!

The basics of data engineering will help you understand the five main components of this field: virtualization, containerization, docker architecture, big data processing, and storage. There’s a lot of talk about data engineering these days. But in order to understand it, you need to understand the fundamentals.

If your “why” for learning data engineering is clear, then your “how” will be easy.
