Kubernetes: do you actually need it?
Kubernetes (often shortened to "K8s") has a reputation as the gold standard for running containers at scale — and also as a source of enormous complexity. Both are true. The real question isn't "is Kubernetes good?" but "do we need it?" Here's how to decide.
What Kubernetes does
If containers package your app, Kubernetes is the system that runs lots of them across many servers — deciding where each runs, restarting failures, scaling up and down, and routing traffic. It automates the hard parts of operating containers at scale. That power comes with a steep learning curve and real operational overhead.
When you probably don't need it
- You're early-stage or run a handful of services.
- A managed platform (or a couple of containers behind a load balancer) already meets your needs.
- You don't have the team to operate it well.
For most products, simpler managed hosting handles thousands of users comfortably — without the complexity tax.
When it earns its place
- You're running many services that need to scale independently.
- You have real, sustained scale and a team to operate the platform.
- You need fine-grained control over deployment, scaling and resilience across environments.
Frequently asked questions
What's the alternative to Kubernetes?
Managed container platforms, serverless, or simply running a few containers behind a load balancer. These cover the needs of most products with far less complexity.
Is Kubernetes only for big companies?
Not only, but it suits teams with real scale and operational capacity. Small teams usually get more value from simpler infrastructure until they truly outgrow it.
Can we migrate to Kubernetes later?
Yes — if your apps are containerised and stateless, moving to Kubernetes when you actually need it is very doable. That's a good reason not to rush.
