One of the most common mistakes small teams make is reaching for Kubernetes before they need it. Compose and Kubernetes are not competitors so much as tools for different scales.
Reach for Compose when
- You run a handful of services on one or two machines.
- Your deploys are simple and infrequent.
- You want a config a new teammate can understand in minutes.
Graduate to Kubernetes when
- You need self-healing, autoscaling, and rolling deploys across many nodes.
- You have the operational maturity to run it — or a managed service that does.
Choose the simplest thing that meets your reliability requirements. You can always migrate later, and “later” is usually cheaper than the complexity tax you pay by adopting Kubernetes too early.
