Kubernetes runs much of the internet, so it's tempting to reach for it by default. For a small team, that instinct often trades a deploy problem you have for an operations problem you didn't. Here's an honest comparison.

Kubernetes is a superb container orchestrator. It's also a large, complex system designed for problems most small teams don't have yet — hundreds of services, many clusters, dedicated platform engineers. The question isn't whether Kubernetes is good. It's whether it's the right amount of machinery for where your team actually is.
Both a PaaS and Kubernetes ultimately run your app in containers behind a load balancer. The difference is how much of the surrounding system you own and operate.
| Self-hosted PaaS | Kubernetes | |
|---|---|---|
| Mental model | Apps, add-ons, deploys | Pods, services, ingress, CRDs… |
| Deploy workflow | Git push | Build image, push, apply manifests |
| Time to first deploy | Minutes | Hours to days |
| Ongoing ops | Own the server | Own the cluster + control plane |
| Zero-downtime, TLS, rollback | Built in | Assemble from components |
| Ceiling / scale | One box (fleet of apps) | Effectively unlimited |
| Who it's for | Small teams, agencies | Large fleets, platform teams |
The cluster itself is the tax. Even managed Kubernetes leaves you responsible for ingress controllers, cert management, autoscalers, node upgrades, RBAC, secrets, and a stack of YAML that grows with every service. None of that ships your product. For a team of a few engineers, the time spent operating the platform can easily exceed the time spent building the app it hosts.
A good heuristic: if you can't name the specific Kubernetes feature you need — multi-cluster, custom operators, thousands of pods — you probably don't need Kubernetes yet.
A self-hosted PaaS collapses that surface area into a handful of concepts you already understand — apps, environment variables, add-ons, deploys — and does the orchestration for you:
This isn't Kubernetes-bashing. There's a real point where it becomes the correct tool: when you're running a large fleet of services, need multi-region clusters, have compliance requirements that map to its primitives, or have enough engineers to justify a platform team. If that's you, its complexity buys real capability. The mistake is adopting that complexity years before you need it.
For most small teams, the right sequence is: start on a self-hosted PaaS, ship product, and reach for Kubernetes only when you hit a wall a single-server platform genuinely can't clear. Because a PaaS runs standard containers, that later migration is far from a rewrite — your app is already packaged the way Kubernetes expects.
If you want Heroku-style simplicity on your own infrastructure today — without the cluster — DeployCloud is built for exactly that team.
Usually not yet. Kubernetes solves problems of scale — large fleets of services, multiple clusters, platform teams. Most small teams get everything they need from a self-hosted PaaS that runs on one server with far less operational overhead.
Not quite. Some PaaS tools run on Kubernetes under the hood, but a single-server PaaS deliberately avoids a cluster entirely — it orchestrates containers on one box with Docker, which is why it's so much simpler to operate.
No. A PaaS runs standard container images, which is exactly what Kubernetes expects. If you outgrow a single-server platform, your app is already packaged correctly — the migration is about infrastructure, not rewriting code.
A self-hosted PaaS like DeployCloud: install it on a VPS, connect a repo, and git push. You get zero-downtime deploys, automatic HTTPS, databases and rollback in minutes, with no cluster to operate.
Self-hosted, open, and yours. Point it at a repo and go — no credit card, no lock-in.
