In Conclusion: Magic DNS

Docker Swarm's overlay networking is one of those beautiful lies we tell ourselves. "Service discovery just works," they said. "DNS resolution is automatic," they promised. Then you're standing in front of a whiteboard trying to explain how microservice 2-C talks to microservice 1-A through an invisible mesh network that somehow resolves names without anyone knowing how.

The red strings connecting everything? That's you frantically gesturing about overlay networks, ingress routing mesh, and VIPs while your colleague's eyes glaze over. Eventually you just wave your hands and mutter something about "embedded DNS server on 127.0.0.11" and hope they stop asking questions.

Spoiler: They never do. Someone always asks "but how does it ACTUALLY work?" and you're back to the conspiracy board.
