Kubernetes vs a Plain VPS: An Honest Cost Breakdown
2026-10-12T00:00:00.000Z
Managed Kubernetes is sold as the grown-up choice. For most small projects it’s overhead with a monthly fee. Here’s the honest math.
What K8s actually costs
- Control plane: free on DO/AKS/LKE, ~$70/mo on EKS, ~$73/mo on GKE Standard.
- Minimum useful cluster: 2 nodes for any real availability → 2× the instance price, always.
- Load balancers: $10–18/mo each on most clouds — and K8s services love to create them.
- Your time: YAML, ingress controllers, cert-manager, node upgrades. Realistically 3–8 hrs/month of maintenance on a small cluster.
What a plain VPS costs for the same workload
One $12–24/mo VPS with Docker Compose, Caddy (automatic TLS), and a restart: always policy runs most side projects and plenty of small production apps. Maintenance: apt update && apt upgrade monthly, ~20 minutes.
When K8s genuinely wins
- You’re running >6 distinct services that scale independently.
- Deploys must be zero-downtime and frequent (the rolling-update story is real).
- Multiple teams need isolated namespaces/RBAC.
- You already know K8s — learning curve doesn’t count against the bill.
When it’s a trap
- A monolith + a database = a VPS. You just spent $80/mo and 4 weekends to host a blog.
- “For the resume” — true, and that’s fine, but call it tuition not infrastructure.
Middle path worth knowing
Docker Swarm (still shipped with Docker), Nomad, or just Docker Compose on a couple of VPSs gets you most of the orchestration benefit with a fraction of the operational surface. K8s at $200+/mo scale; Compose until then.
