Kubernetes: When Is It Really Worth It?
Kubernetes is the standard for container orchestration. But not every company needs Kubernetes. An honest look at costs, complexity, and alternatives.
What Kubernetes Can Do — and What It Can’t
Kubernetes Solves
- Auto-scaling during load peaks
- Zero-downtime deployments
- Self-healing during outages
- Multi-cloud and hybrid cloud
- Microservice orchestration
Kubernetes Does NOT Solve
- Poorly written code
- Missing monitoring strategy
- Organizational problems in the team
- Security vulnerabilities in the application
- Excessive cloud costs (can even increase them)
The Kubernetes Cost Reality
Kubernetes itself is open source — but the actual costs go far beyond infrastructure.

Alternatives Compared
| Criterion | Kubernetes | ECS / Fargate | PaaS (Railway, Render) | Classic VMs |
|---|---|---|---|---|
| Complexity | High | Medium | Low | Low |
| Scaling | Automatic & granular | Automatic | Automatic with limits | Manual |
| Costs from | €300+/month | €50+/month | €20+/month | €20+/month |
| Team Requirement | K8s expertise required | Basic container knowledge | Minimal | Linux admin |
| Vendor Lock-in | Low | AWS-bound | Platform-bound | Low |
| Ideal for | 10+ services & microservices | AWS-centric containers | Small teams & quick start | Monoliths & legacy |
When Kubernetes Makes Sense — and When It Doesn’t
Kubernetes fits when...
- You operate 10+ microservices
- Deploy multiple times daily
- Auto-scaling is business-critical
- Multi-cloud strategy is planned
- Dedicated DevOps team available
Kubernetes is overkill when...
- You operate a monolith
- Fewer than 5 services running
- No DevOps know-how in the team
- Budget under €3,000/month for infrastructure
- Deployments less frequent than weekly
Our Honest Conclusion
Kubernetes is powerful — but not for everyone. If you have the team and the complexity, it’s the right choice. If not, simpler alternatives like ECS/Fargate or a PaaS can save you months of setup and thousands in operating costs.
We help with both: Kubernetes when it fits — and simpler alternatives when it doesn’t. No dogma, just the solution that fits your situation.
Frequently Asked Questions
When does Kubernetes make sense for my company?
Kubernetes typically makes sense starting from about 10 microservices, a team of at least 5 developers, and multiple deployments per week. For smaller setups with few services, alternatives like AWS ECS/Fargate or a PaaS are often the better choice.
What does Kubernetes cost to operate?
A managed Kubernetes cluster (e.g., EKS, GKE) starts at around €300/month for infrastructure alone. A production-ready setup with monitoring, ingress, and CI/CD runs €1,000–2,000+/month. Add personnel costs: A DevOps engineer with Kubernetes experience costs between €75,000 and €95,000/year according to the 2025 Stepstone Salary Report.
What alternatives are there to Kubernetes?
The main alternatives are AWS ECS/Fargate (containers without cluster management), PaaS providers like Railway or Render (minimal operational overhead), and classic VMs with auto-scaling. The choice depends on team size, complexity, and budget.
Do I need a dedicated DevOps team for Kubernetes?
Yes, at least one experienced DevOps engineer with Kubernetes expertise. The learning curve to productive use is 3–6 months. Alternatively, an external partner can handle operations or support your team during the rollout.
Does Kubernetes make sense for a monolith?
In most cases, no. Kubernetes shows its strengths with distributed systems with many services. For a single monolith, Kubernetes is overkill — a PaaS or simple container solution is significantly more cost-effective and easier to operate.
