## What it is
Dragonfly is a CNCF Graduated P2P-based file and container image distribution system that accelerates large-scale delivery of images, OCI artifacts, AI models, and other files. It includes Manager, Scheduler, Seed Peer, and Peer components, plus optional Nydus content-addressable filesystem support for faster container launches.

## Use cases
- speed up docker image pulls in a large kubernetes cluster
- distribute AI model weights and datasets across many nodes
- reduce registry bandwidth costs with p2p image distribution
- accelerate OCI container startup with nydus snapshotter
- preheat images from harbor before deployments
- share large log or cache files across a datacenter

## When to choose
- you run large-scale clusters where image pulls saturate registry bandwidth
- you need to distribute big files or AI models to many peers efficiently
- you want a CNCF graduated, production-proven solution used by major companies

## When to avoid
- small clusters where a plain registry pull is fast enough
- you cannot deploy extra infrastructure components (manager, scheduler, seed peers)
- you need simple single-node downloads without p2p coordination
