Proxmox, Pterodactyl, Git CI/CD, Nginx, Cloudflare and OVH. Everything else runs on this.
Proxmox for virtualization and Pterodactyl for game servers. Multi-node setups where you can create, move and manage servers without SSH-ing into six different machines.
Git pipelines that push config, plugin and code changes safely, so updating on a Friday isn't scary anymore.
Nginx reverse proxies, Cloudflare for DNS, CDN and DDoS protection, and OVH dedicated servers when a project needs its own hardware instead of a VM.
