Stage 5: Certification & Specialization

**CKA Path** (after Stage 2): KodeKloud Mock Exams #2, #3 → Schedule exam **CKAD Path:** KodeKloud CKAD Course + Mock Exams (focus: app deployment, config, observability) **CKS Path:** KodeKloud CKS Course + Mock Exams (requires CKA first) **Cloud Specialty:** AWS Certified DevOps Engineer, Azure DevOps Engineer Expert, GCP Cloud DevOps Engineer **Platform Engineering:** CNCF Platform Engineering Maturity Model self-assessment **Recommended sequence:** CKA → (CKAD or CKS) → Cloud Specialty → Platform Engineering portfolio

Platform Recommendations by Stage

| Stage | Primary Platform | Supplemental | |---|---|---| | 1 Foundations | **KodeKloud (Free/Standard)** | Linux Journey, Docker Docs | | 2 K8s Core | **KodeKloud Pro** | KubeAcademy, KillerCoda | | 3 CI/CD | **GitHub Actions / GitLab (free)** | ArgoCD/Flux docs, Dagger | | 4 Cloud/Platform | **Cloud free tiers + KodeKloud Pro/Business** | Crossplane, Backstage, Port docs | | 5 Certs | **KodeKloud Pro (mocks)** | Linux Foundation practice exams | **Team note:** Stages 3–4 benefit significantly from **KodeKloud Business** — custom paths align to your stack, SSO/SCIM for access, dashboard for manager visibility.

Timeline Summary

- **Full-time (40 hrs/wk):** ~10 months to hireable Platform Engineer - **Part-time (15 hrs/wk):** ~22 months - **Certification-only (CKA):** 3–4 months part-time **Adjust for your background:** Sysadmins skip Stage 1. Developers accelerate Stage 3. Cloud cert holders compress Stage 4.

Common Pitfalls

1. **Tutorial hell** — Watching without doing. Fix: 80% hands-on, 20% video. 2. **Skipping foundations** — Weak Linux/Git/Docker haunts you in K8s. Fix: Stage 1 is non-negotiable. 3. **Certification obsession** — Certs validate, they don't teach. Fix: Learn → Build → Certify. 4. **Tool fatigue** — You don't need ArgoCD + Flux + Tekton + Jenkins. Pick one per category. 5. **Solo grinding** — Join communities (KodeKloud Discord, CNCF Slack, r/devops). Accountability + exposure to real problems.
