Everything DevOps.
One Acme Corp story.

Nine scenario-based tracks that follow one company — Acme Corporation — as it transforms delivery: architect the system, secure it, automate it with pipelines, and run it on the cloud with Kubernetes.

Scenario-driven. Trade-off aware. Simplified — because we are StackSimplified.

Foundations

⚙️
Architect

DevOps

Think, decide, and design like a DevOps Architect: CALMS & DORA, CI/CD platform, branching, deployments, observability, and platform engineering.

DevSecOps

Bake security into the same pipeline: shift-left (SAST/SCA/secrets), supply-chain (signing, SBOM, SLSA), runtime, and govern-detect-respond.

Deploy model

GitOps

Git as the source of truth, reconciled continuously. Argo CD & Flux, drift detection, progressive delivery, secrets, and multi-cluster.

Intro + roadmapStart →

CI/CD Platforms

🐙
Hands-on CI/CD

GitHub Actions

Workflows, jobs, steps, runners; CI/CD, reusable workflows, OIDC; and security — Dependabot, CodeQL, secret scanning, DAST & GHAS.

Hands-on CI/CD

GitLab CI/CD

One .gitlab-ci.yml, end to end: pipelines, stages, jobs, runners, environments, Auto DevOps, and built-in SAST/DAST security scanning.

📚 One story, end to end

Every track follows the same Acme Corporation journey, so the learning connects. Architect the delivery system, secure it, adopt GitOps, automate it with your CI/CD platform of choice, then run it on managed Kubernetes in the cloud — the way it happens in a real company.
