Know the goal
The target is a first Cloud / DevOps Engineer role (medior level) within 12 months. Later: Senior or Platform Engineer, then a specialisation: Cloud Security, Platform Architect or MLOps.
The base skills every DevSecOps job asks for:
| Skill | Why it matters | Where I learn it |
|---|---|---|
| Linux | Every server, container and Kubernetes node runs Linux | RH124, RH134, RHCSA |
| Cloud (Azure) | Most companies run in a public cloud | AZ-104 |
| Infrastructure as Code | Servers and networks are built from code, reviewed and repeatable | Terraform |
| Git and CI/CD | Every change goes through a pipeline: build, test, scan, deploy | Git, GitHub Actions |
| Containers and Kubernetes | The standard way to run apps | Containers, CKA |
| Security | Built into every step, not added at the end | CKS, GitOps |
| Scripting | Automate the boring work | Python, Bash in RH134 |
Onthoud
DevSecOps = development + security + operations as one flow. The pipeline builds, tests, scans and deploys; security checks run automatically on every change.
Follow the 5 phases
One phase at a time. Each phase has a certificate, a course, a book and a project.
Use the same method in every phase
Read the official exam objectives first, follow one main course, practise every day, then do practice exams.
- Open the official objectives and copy them into a checklist.
- Take one main course (★ in the resource lists). Do not collect courses.
- Do labs every day, even 30 minutes. Break things and fix them.
- Write one summary page per topic on this site, in my own words.
- Do practice exams with a timer. Book the real exam only when I score 85 %+ several times.
- Finish the phase project and publish it on GitHub.
Op het werk
Free first. Microsoft Learn, the Kubernetes docs, the Terraform tutorials and the Red Hat developer subscription cost nothing. Pay only for the exams and one or two good courses.
Know what each phase costs
The exams are the main cost. Prices change — always check the official page before you book.
| Exam | About | When |
|---|---|---|
| RHCSA (EX200) | $500 | Months 1 – 2 |
| AZ-104 | $165 | Months 2 – 4 |
| Terraform Associate (004) | $70.50 | Months 4 – 5 |
| CKA | $445 (one free retake) | Months 5 – 8 |
| CKS | $445 (after CKA) | Months 9 – 12 |
| Total | about $1,625 (about $1,180 without CKS) |
Op het werk
The Linux Foundation has big seasonal discounts (for example in November). CKA and CKS are often sold together for less.
Track progress every month
Small, visible steps every month keep the plan alive.
- One certificate about every 2 – 3 months.
- One project published on GitHub every month.
- Two short LinkedIn posts every week about what I learned.
- This site: summaries, command pages and lab notes grow with every phase.
Let op
Teams get smaller because of AI tools. Hands-on work (projects that run, pipelines, clusters) matters more than the number of certificates.
