The short version

  • Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; Melio card payments incur flat 2.9% fee on all plans
  • They diverge on capability: Docker covers Container runtime, Melio covers Vendor payments.

Where each one falls short

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

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

Melio

  • Card payments incur flat 2.9% fee on all plans
  • International payments charged $20 flat fee or 2.9% conversion rate plus international fees
  • Paper checks cost $1.50 per check
  • Wire transfers cost $10 standard or up to 1% plus $10 for same-day processing
  • Core and Boost plans charged $10/month per additional user beyond base
