Dragonfly

Dragonfly moves the same data to many machines without making the origin serve every copy. It is a cloud-native distribution system built around peer-to-peer transfer. A peer that has data can upload pieces to other peers.

This matters when a fleet starts at once. A new image rollout, node scale-out, or model deployment can make thousands of machines request one artifact. Direct downloads concentrate traffic and failure risk at the registry, object store, or HTTP server. Dragonfly lets the first download enter the peer network, then lets later peers obtain pieces from one another.
