If you’re thinking about getting into data engineering, you’ve probably heard the term ‘DevOps’ mentioned. But what is it, why is it relevant to data engineers, and how do you learn those skills?
What Is DevOps?
At a simple level, DevOps is about building, deploying, and running pipelines and applications smoothly. It combines development and writing code (Dev) with operations, or running systems (Ops).
Once you’ve written some code, DevOps helps you:
- Get your code running in the real world and on the cloud
- Keep it reliable
- Update it without breaking things
Why DevOps Matters for Data Engineers
Imagine you’ve built a data pipeline on your laptop. It works perfectly, but that’s not actually enough. It will need to run every day, with more data, and be usable by other people.
For data engineers, this means taking your data pipelines and making sure they:
- Run automatically
- Handle real-world data
- Scale when needed
DevOps gives you the tools to do so, helping you move from ‘This data pipeline works locally on my machine’ to ‘It works reliably in the cloud for everyone.’
Overall, DevOps is the difference between being able to build an isolated data project, and being able to run a full data system like a professional.
What You Need to Learn
There are some key DevOps-related skills that you need to know to work efficiently as a data engineer.
These are all covered on weeks 5 and 6 of Northcoders’ Data Engineering, AI & Machine Learning Bootcamp, which trains beginners to become junior data engineers.
- Running Code in the Cloud (Compute)
You need to be able to run your code on remote servers, not just locally on your own computer.
You’ll work with:
- EC2: Think of it as renting a computer in the cloud
- Lambda: Running small bits of code without managing a server
Why this matters:
- Your data pipelines can run anytime
- You’re not dependent on your laptop
- It’s how real companies operate
- Storing Data Properly (Cloud Storage)
Data needs a safe, organised place to be stored in.
You’ll use:
- S3: Store files (like datasets, logs, outputs)
- RDS: Store structured data in databases
Why this matters:
- Your data is secure and accessible
- You can handle much larger datasets
- Teams can share and use the same data
- Infrastructure as Code (IaC) with Terraform
Instead of manually setting things up, you can write code that builds your infrastructure for you.
With Terraform, you can:
- Create servers
- Set up storage
- Configure systems
Why this matters:
- You can recreate your setup anytime
- Fewer mistakes
- Everything is consistent and repeatable
- CI/CD (Continuous Integration & Deployment)
This is about automating your workflow. Instead of manually updating your project every time you make a change, you can:
- Push your code
- Tests run automatically
- Your project updates automatically
Why this matters:
- Saves time
- Reduces errors
- Keeps everything up to date
- Orchestration (Making Everything Work Together)
Data pipelines often have multiple steps:
- Extract data
- Transform it
- Load it somewhere
Orchestration tools help you:
- Run these steps in the right order
- Handle failures
- Schedule jobs
Why this matters:
- Your pipelines run reliably
- You don’t need to manually trigger everything
- It scales easily as your project grows
Bringing It All Together
DevOps might sound like a big, complicated topic, but for data engineers, it’s really about one thing: making your data projects work in the real world.
If you want to build systems that companies actually use, not just projects that sit on your laptop, these skills are essential.
If you’re excited about turning data into real, working systems, through the Data Engineering, AI & Machine Learning Bootcamp, you’ll understand how to:
- Deploy a real data application
- Store and manage data in the cloud
- Automate workflows
- Build systems that actually run in production
You don’t need any tech experience to join the bootcamp, only foundations in Python. If you’re new to Python, Northcoders will give you access to free materials to learn what you need from scratch in your own time.
If you’re already an experienced Python developer familiar with databases and looking to upskill in Cloud Engineering and DevOps specifically, Northcoders also offers a 2-week Upskilling in Cloud Engineering and DevOps Course.

What Is RAG and Why Does It Matter for AI Systems?
If you’ve been exploring AI, data engineering, or machine learning, you’ve probably seen the term ‘RAG’ popping up more and more. RAG stands for Retrieval-Augmented Generation, and it’s quickly becoming one of the most important ideas behind modern AI systems. Let’s look at a simple definition, and why it’s so relevant. What Is RAG? Retrieval-Augmented…

Data Engineering vs. Data Science vs. Data Analysis: What’s the Difference?
Job titles like data engineer, data scientist, and data analyst all sound pretty similar. Are they all different names for the same thing, or actually individual roles? While all three roles work with data, they focus on separate parts of the data’s journey. Each role interacts with it in different ways, at different times, and…
Build AI Skills, Stay Ahead in Your Career
Headlines regularly warn against a scary future: that our jobs will be replaced by AI. But the truth is more nuanced. AI doesn’t take over jobs on its own. However, as people start using AI skills and tools and become more efficient, how the work gets done changes. This is similar to how spreadsheets and…
What Is OOP? A Beginner’s Guide to Object-Oriented Programming
If you’ve started learning to code, you might have heard the term OOP, or Object-Oriented Programming. The name can sound intimidatingly technical, but it’s simply a way of writing code, and one which mirrors how we already think about the world. Once it clicks, it can make your code easier to understand, change, and work…
Becoming a Lifelong Learner: How to Stay Curious in the Tech Industry
The tech industry moves fast, very fast. New programming languages, frameworks, and tools appear constantly, and what’s cutting-edge today might be outdated in a few years. For developers, that can feel both exciting and overwhelming. But there’s one quality that helps you thrive in the tech industry, no matter how quickly things change: curiosity. Being…
Can I Teach Myself to Code? The Pros and Cons of Self-Taught Coding
Learning to code has never been more accessible. With thousands of free tutorials, YouTube channels, and online courses available, it’s easy to see why many people start with self-taught coding, rather than more traditional guided training. Self-teaching coding can be rewarding, but it’s not without its challenges, especially if your goal is to land a…
