The Recommended Starter Stack
If you’re starting from scratch and want a production-ready DevOps stack with minimal complexity:
- Cloud: DigitalOcean (simplest) or Vultr (cheapest)
- Orchestration: Kubernetes (DOKS or VKE, free control plane)
- IaC: Terraform
- CI/CD: GitHub Actions + Argo CD
- Monitoring: Prometheus + Grafana
- Security: Trivy + GitLeaks + Kyverno
- Ingress: Nginx + cert-manager
This stack handles everything from solo projects to mid-size production workloads. Scale up to enterprise tools (Datadog, Backstage, Crossplane) as your team and complexity grow.
