Having file stored in a central service like S3 plus using CDN properly, we can get the durability (by S3) and performance/latency issue solved (by CDN), and by the way, with CDN the network bandwidth usage is significantly reduce as CDN will cache the hot data on the edge (and who cares the cold data anyway). I would like to hear someone give a fair comparison here – because an entirely new storage paradigm needs to be significantly better than the existing system to really get meaningful traction.
IPFS based storage solution does seem to provide the conceptual benefit, as most decentralized solutions sounds at the very beginning. However, other than inertias created by the above ‘good enough’ solution that every major service is using and designed upon, I see another big problem to store data on the last mile devices, and that is the asymmetry of uplink/downlink bandwidth. Mike Chamber (the last comment in this thread) described it, and I’d really like to hear people’s response to that.
