Behind the Scenes of the Cloud
summary
A small hosting operator describes running an 18-person shop that owns a Tier‑4 certified datacenter (certified Jan 2021) with two 250 kVA generators (24‑hour autonomy), UPS banks and a cold‑corridor layout to separate power and cooling. Networking uses BGP with its own public AS connected to about 34 peers and RPKI validation, with monthly failover tests and monitoring; storage combines SSDs for hypervisors and HDDs for bulk and backup and relies on routine simulated failures to verify redundancy.
