I’ve seen it dozens of times: a seed-stage startup with three engineers decides they need Kubernetes because “that’s what the big companies use.” Six months later, they’re spending more time managing their cluster than building their product.

Don’t get me wrong—I love Kubernetes. I’ve architected and operated production clusters handling millions of requests. But K8s is a solution to a specific set of problems, and if you don’t have those problems, you’re just adding complexity.

When Kubernetes Makes Sense

Kubernetes shines when you have:

  • Multiple services that need to communicate and scale independently
  • Traffic patterns that vary significantly (auto-scaling becomes valuable)
  • Compliance requirements that benefit from namespace isolation
  • A dedicated platform team or at least one engineer who can focus on infrastructure

If you’re running a monolith with predictable traffic and a team of five, you probably don’t need it.

What to Use Instead

For most early-stage startups, I recommend starting with:

  1. A simple PaaS like Render, Railway, or even Heroku
  2. Managed services for databases, caching, and queues
  3. A single cloud provider to avoid multi-cloud complexity

You can always migrate to Kubernetes later when you actually need it. The migration is straightforward if you’ve containerized your applications—and you should be containerizing regardless of where you deploy.

The Right Time to Consider K8s

Start evaluating Kubernetes when:

  • You’re running 5+ services that deploy independently
  • Your infrastructure spend exceeds $10k/month (platform engineering ROI kicks in)
  • You’re hitting limits with your current PaaS
  • You have compliance requirements that need fine-grained control
