Kubernetes is an orchestration layer for teams whose service count, scaling needs and operational sensitivity have moved beyond simpler runtime models.
1. What does Kubernetes actually do?
Kubernetes manages how containers run: scheduling, networking, rollout logic and self-healing. That keeps deployments from depending on scattered scripts and manual routines.
2. When does it become useful?
Once you have multiple services, more frequent releases and a real need for scaling or service discovery, Kubernetes begins to justify its complexity.
3. When is it too early?
If the team is still moving with one or two straightforward services, VPS or cloud containers without full orchestration may be the better fit. Added complexity should earn its place.
