Dragonfly: an intelligent P2P based file distribution system

Previous discussion (269 points, 58 comments) https://news.ycombinator.com/item?id=17303055

The context is that Dragonfly has recently been proposed to the CNCF Sandbox[0]. Checkout the HN previous thread[1].

I've worked on P2P distribution systems and found that not many people are able to reuse these systems because of assumptions about the network that are not consistent across all environments. Eager to hear if anyone besides Alibaba is using Dragonfly as a counterpoint.

Anyone have any views on if this is materially different to Dat for the same challenge? https://github.com/datproject/dat

Does anybody know the differences with IPFS? https://ipfs.io/

Forgive this noob, but I was wondering what use cases infrastructure like this is used for. I have only read a little about containers and have seen plenty of projects working with them, but then I see that this project is also related. Can anyone point me to where I can read about the use cases of all of these and how they fit in real world applications? Thank you!
