Alright so I’m not an expert so I might not be explaining it correctly.
Federated Network: Multiple instances sharing content, such as Lemmy
Peer to Peer Network: There is no “instances”, just peers. Many peers sharing content. Every user is a peer. There is no server costs, because every device connected to the network is acting like a mini-server. It will cost your device some storage space and network bandwith depending on the how the software is designed.
Or do you think Centralized servers are still gonna dominate the future?
Storage is cheap but most of the instance operators that are setting up right now aren’t prepared for how much storage they’re going to need and it’s associate costs. I’m not talking the big boys like .World, but the hundreds of private and semi-private instances being set up on $12/mo VPS and such.
After 30 days of running my single user instance I’m at 23GB of storage. Since I’m using on prem equipment I have the lowest cost per GB possible and am not the least concerned. We’re going to see a ton of attrition with hosted instances as the costs of ownership goes from 10, to 20, to 40, to $50+/mo. due to storage. Many aren’t in anyway prepared to tackle the topic of moving PICTRS off to object storage or engage in other mitigations.
