Docker vs Kubernetes - When do you need K8s?

I understand Docker well, but I'm confused about when to adopt Kubernetes.

For a startup with 3-4 microservices, is K8s overkill? Or should we plan for it from the start?

What factors should influence this decision?

For 3-4 microservices, Docker Compose is enough.

K8s adds complexity that you don't need yet. You can always migrate later when you have:
- 10+ services
- High availability requirements
- Auto-scaling needs

Start simple, scale when needed!

Agree with the above. I'd add that K8s has a steep learning curve.

Use Docker Compose now, focus on building your product. When you're successful and need to scale, then invest time in K8s.
