Do You Actually Need Kubernetes? Probably Not.

I have set up Kubernetes for 15 startups. Only 3 of them actually needed it. The other 12 would have been better off with Docker Compose and a managed host. Here is how to tell which one you are.

You need Kubernetes when you have 3+ services with different scaling requirements, a dedicated DevOps person, and predictable traffic patterns. If you have none of those, Docker Compose + a VPS or managed host will serve you better at 1/10 the complexity.

I worked with a startup that spent 4 months setting up Kubernetes before writing any product code. They had 5 people. Two backend engineers spent half their time on K8s YAML, helm charts, and networking configs. The founder asked me to audit their setup.

The Kubernetes Tax On Small Teams

I worked with a startup that spent 4 months setting up Kubernetes before writing any product code. They had 5 people. Two backend engineers spent half their time on K8s YAML, helm charts, and networking configs. The founder asked me to audit their setup. I asked one question: 'How many services do you run?' Answer: 2. A web app and a worker. Two services. Docker Compose would have handled that in an afternoon. They wasted $40,000 in engineering salary on complexity they did not need. This is not an extreme case. I see it every 3 to 4 months. A founder reads that 'Kubernetes is the standard for production' and jumps to it before their app has paying customers.

The Decision Tree I Use With Clients

Question 1: How many services do you run? If fewer than 3, use Docker Compose. Question 2: Do you have a dedicated DevOps person? If no, use a managed platform. Question 3: Does your traffic vary by 10x or more daily? If no, use a fixed VM size.
Question 1: How many services do you run? If fewer than 3, use Docker Compose. Question 2: Do you have a dedicated DevOps person? If no, use a managed platform. Question 3: Does your traffic vary by 10x or more daily? If no, use a fixed VM size. Question 4: Do you need to run different services on different hardware (GPU for ML, high memory for databases)? If no, a single server class works. If you answered 'no' to any of these, Kubernetes is premature. This is not a judgment. It is a cost calculation. K8s costs 5 to 10 hours of engineering time per week to maintain. That time should go into your product.

Managed Platforms That Replace Kubernetes

Railway, Render, Fly.io, and Google Cloud Run all handle container orchestration for you. You push code. They handle routing, scaling, and networking. No YAML. No cluster management. The cost is slightly higher per unit of compute, but the total cost of ownership is lower because you spend zero engineering time on infrastructure.

The cost is slightly higher per unit of compute, but the total cost of ownership is lower because you spend zero engineering time on infrastructure. For a startup under 20 people, this is the right tradeoff. Pay $100/month more for compute. Save $3,000/month in engineering salary. I have used Railway for 4 client projects in 2025. Zero infrastructure issues. Zero late night pages. I cannot say the same for any self managed Kubernetes cluster I have worked with.

5 Tips to Get Started

1

Under 10 people: use Docker Compose on a single VPS. DigitalOcean costs $50/month. Kubernetes would cost $200/month plus your sanity.

2

10 to 30 people: use a managed container platform (Railway, Render, Fly.io). They handle orchestration. You do not touch YAML.

3

30+ people: consider Kubernetes ONLY if you have a dedicated DevOps person AND 3+ microservices with different scaling needs.

4

You do not need Kubernetes if one Docker Compose file covers all your services. That means your architecture is simple enough to skip it.

5

You do not need Kubernetes if your traffic is predictable. K8s auto scaling matters when you get 10x traffic spikes. Otherwise a fixed VM is cheaper.

Frequently Asked Questions

When does a startup actually need Kubernetes?

Three conditions: you have 3+ microservices that scale independently, you have a dedicated DevOps person, and your traffic has unpredictable spikes. If any of those is missing, K8s is premature.

What is the simplest alternative to Kubernetes?

Docker Compose on a single VPS. If you outgrow that, use a managed container platform (Railway, Render, Fly.io). They handle scheduling, networking, and scaling without the K8s complexity.

How much does Kubernetes actually cost for a small startup?

Managed K8s (EKS, AKS, GKE) costs $70 to $150/month in control plane fees alone. Then add worker nodes ($100 to $500/month), storage ($50 to $200/month), and networking ($50 to $200/month). Total: $300 to $1,000/month for a setup that adds zero business value.

Can I migrate to Kubernetes later?

Yes. Design your app as containers from day one. Use Docker Compose for local dev and production. When you outgrow it, the migration to K8s is straightforward because your app is already containerized.
