BYOC build vs. buy: 3-year cost
Estimate the engineering cost of running your software inside your customers' cloud accounts, in-house versus with Nuon.
Build vs. buy, 3-year TCO
Illustrative estimate. Nuon pricing depends on your fleet and agreement.
Over 36 months, Nuon is $805K lower than in-house.
How this is calculated
How the 3-year totals are built
In-house totals the one-time build (when starting fresh or adding Day-2 features; skipped as already paid when you have existing customers and no Day-2 toggles) plus monthly onboarding, releases, support, and platform engineering across 36 months. Nuon totals setup (app configs, integration) as separate one-time lines, plus ongoing platform and ops work over the same period. Totals use your loaded engineer cost and the effort assumptions shown.
Built in-house
One-time build and year-3 run rate if you build and operate BYOC yourself. Nuon is in Build vs. buy above.
72 customer installs by month 36 (0 existing + 2/mo × 36)
How this is calculated
In-house year-0 build cost
One-time engineering cost to stand up BYOC when you have no existing customers, plus any Day-2 features you toggle on. Shown as dollars and engineer-months at your loaded salary.
How this is calculated
In-house year-3 run rate
Sum of in-house onboarding, release rollout, customer support, and platform engineering over months 25–36, expressed as a yearly cost and FTE at your loaded salary.
How this is calculated
Year-3 maintenance per install-month
Year-3 annual maintenance divided by the sum of installs across months 25–36. Engineering load only — not cloud spend. Rounded to the nearest $10.
Annual maintenance breakdown
- Platform engineering$244K (41%)
- Release & rollout$116K (20%)
- Customer support$194K (33%)
- Onboarding new customers$41K (7%)
