Pay for the edge.
Your hardware is free.
Run servers on your own machines (BYON) and only pay for the managed DDoS edge, traffic and backups. Or just rent a protected address for a server you already run.
One BYON node and one route-only location per account. Each includes a handful of free subdomains on our domains - point your own domain at the edge with a CNAME and there is no limit on addresses at all. Traffic is billed by usage, and only if you switch metered billing on.
