The short version

  • Only Docker has a free tier, so it costs nothing to try first.
  • Each has a real cost: Contabo fully unmanaged infrastructure requires all setup and maintenance by customer; Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • They diverge on capability: Contabo covers VPS Hosting, Docker covers Container runtime.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Contabo

  • Fully unmanaged infrastructure requires all setup and maintenance by customer
  • No formal SLA with financial compensation for downtime violations

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments
