Standardizing OpenStack + Ceph deployment took us from 20 person-days per cluster with two engineers to 5 with one. Deployment time was the smaller half of the payoff.
Environment: Viettel private cloud — 10 OpenStack clusters with Ceph, bare metal, each deployed for a separate tenant organization across different data centers. Standardization was non-optional: every difference tolerated at deployment became one we had to remember at incident time, for a cluster we might not touch again for months.
Where the 20 person-days went — five recurring sources:
— Non-standardized tooling
— Manual hardening: many-item checklist applied by hand
— Manual integration: OpenStack,Ceph, monitoring, logging
— Piecemeal validation: no end-to-end gate, defects surfaced at handover
— Environment drift: failures no runbook anticipated
Drift produces defects, piecemeal validation finds them too late, and hand-built clusters keep charging in incidents and support long after handover. The highest-leverage fix: gate the environment before deploying, not the deployment after.
Attendees leave with a five-category diagnostic framework and a pre-deployment validation checklist for bare-metal OpenStack + Ceph.
