You’re a developer or sysadmin, you keep seeing job posts for DevOps engineers, and you wonder if it’s worth the switch. I’d say yes, if you like automation and fixing things at the seams between code and servers. This post covers what the role is, why it’s in demand, which skills to learn and how to start.
What is DevOps?
DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). Its goal is to keep the software life cycle running smoothly while developers ship features, fixes and updates often.
Today, DevOps is integrated into cloud-native, AI-driven, and security-first environments.
It’s no longer about automation only, it’s about building smart, scalable, secure systems from day one!
Why are DevOps engineers in high demand?
Companies need DevOps engineers because modern software depends on cloud, automation and security, and someone has to connect them. Here are the four main reasons I see.
Every serious tech company needs DevOps
From fintech to e-commerce to gaming, every company that builds software needs a DevOps team.
And not just big companies. Even small startups now include DevOps from day one.
Cloud adoption keeps growing
With over 80% of businesses running on cloud in 2025, managing cloud infrastructure efficiently is critical.
DevOps engineers make that happen using tools like Terraform, Kubernetes, and CI/CD pipelines.
Security is shifting left
Security is no longer a final step. It’s built into the pipeline, and that practice is called DevSecOps. DevOps engineers who know security best practices are highly valued.
AI adds automation complexity
AI-generated code, self-healing systems and smart monitoring tools mean teams need new workflows. DevOps engineers are the bridge between those tools and real-world reliability.
What skills do DevOps engineers need?
A DevOps engineer needs cloud, infrastructure as code, containers, CI/CD, monitoring, scripting and security skills, plus good communication. Here’s the map I’d follow:
| Skill area | Tools and topics |
|---|---|
| Cloud platforms | AWS, Azure, GCP |
| Infrastructure as Code (IaC) | Terraform, OpenTofu, Pulumi |
| Containers and orchestration | Docker, containerd, Kubernetes |
| CI/CD pipelines | GitHub Actions, GitLab CI, Jenkins |
| Monitoring and observability | OpenTelemetry, Prometheus, Grafana |
| Scripting and automation | Shell/Bash, Python, Ansible, Puppet |
| Security and compliance | DevSecOps, SSM, RBAC, OAuth |
| Soft skills | Problem-solving, communication, teamwork |
How to start a DevOps career
You can start a DevOps career in six steps: learn Linux and networking, practice Git, build a CI/CD pipeline, learn a cloud, build projects, and keep learning.
1. Learn Linux and networking basics
You need a solid grip on Linux and networking. You don’t have to master every system call or protocol. But you should be comfortable in the command line, understand IP addressing and handle basic configuration. If you want a hardening exercise, try my Linux server hardening checklist.
2. Practice Git
Git is how teams track changes, manage versions and build together without breaking everything. Practice daily with GitHub or GitLab. Learn to branch, merge, resolve conflicts and use pull requests.
3. Build your first CI/CD pipeline
Build a basic pipeline for a simple app. Use GitHub Actions or GitLab CI to build, test and deploy the code.
Keep it small. A static site is enough. The goal is to understand the path from commit to production.
4. Get cloud certified
Learn AWS, Azure or Google Cloud, and consider a certification like AWS Certified DevOps Engineer or Azure DevOps Expert. Certs show you’re serious, and cloud platforms are the base of scalable infrastructure.
5. Contribute to open source or personal projects
DevOps is about doing, not just knowing. Automate something fun or contribute to open source. Use Docker to containerize your app, write Terraform to define the infrastructure, and document it all on GitHub in Markdown. That gives you confidence and a public portfolio. My post on Dockerfile best practices is a good place to level up your images.
6. Stay current
DevOps changes fast. Follow blogs, subscribe to newsletters, join communities (Kaliex is one), and watch conference talks. Stay curious.
Is DevOps worth it?
Yes. If you enjoy automation, solving problems and working with both code and infrastructure, DevOps is one of the most rewarding careers in tech.
It’s a mindset more than a job title. DevOps engineers build bridges between devs, ops and the business, and companies keep needing that.

Frequently asked questions
Do DevOps engineers need to know how to code?
Yes, but you don't need to be a full-time software developer. You should be able to write scripts in Bash or Python and read application code. That's enough to automate tasks and debug pipelines.
How long does it take to become a DevOps engineer?
It depends on your starting point. Someone with sysadmin or development experience can often move faster than a complete beginner. Following the six steps with real projects matters more than any fixed timeline.
Do I need a certification to get a DevOps job?
No. Certifications like AWS Certified DevOps Engineer help show your knowledge, but a portfolio of working projects often says more. Ideally you have both.
What is the difference between DevOps and DevSecOps?
DevSecOps is DevOps with security built into every stage of the pipeline instead of added at the end. Most DevOps engineers are now expected to know the basics.
