IF you (or want to) OPERATE a NOSTR #RELAY you can do it any RESOURCES

(1CPU 1GB RAM 10GB SSD 5Mbps Network or 12CPU 64GB RAM 500GB SSD or VPN cloud or RasPI or anything)

Key is RATE LIMIT RESOURCES based what you have or can afford to allocate. self-custody hardware or vps/cloud always check your real UTILIZATION and do baselining based on monthly usage using time series graphs.
