Servers are idle. How to monetize?

Question

Business Informatics

Servers in the DC are idle. I'm not very good myself, I can roll both Win and * nix systems, no more. Tell me how you can earn extra money on them?

Answer 1

There are probably no easy ways.
You can place something "for your own" on them, by agreement for a nominal fee, for example, business applications of existing customers. A kind of SaaS in miniature.
You can organize hosting by installing a hypervisor on them and dividing them into virtual machines, selling them and ensuring their uninterrupted operation. Either by agreement with existing customers (easier), or open a panel and automate payments.
You can re-rent them to someone else, but usually server tenants know roughly what they need and where they can find it profitable. Significant markups (your margin) on such hardware can be repulsive.
