✓ Pros

  • Docker: Simple and efficient
  • K8s: Infinite scalability and self-healing

✗ Cons

  • K8s: Massive learning curve
  • Docker: Harder to scale horizontally across servers

The Complexity Trap

Every developer wants to put Kubernetes on their resume. But for 80% of projects, it introduces massive complexity for zero business value.

When Docker Compose is Enough

If you have a frontend, a backend API, a Postgres database, and a Redis cache, Docker Compose on a single VPS is all you need. It is simple to debug, cheap to host, and fast to deploy.

When You Need Kubernetes

K8s is necessary when you have high availability requirements (zero downtime scaling), microservices managed by different teams, and traffic that spikes unpredictably. If you aren't doing millions of requests a day, K8s is likely overkill.
