DT directly manages 45% of the City's ~5,200 servers; 55% run in department environments outside central management.
Not measured — estimated scale Estimates, not counts

Rough assumptions for departments running largely outside our visibility. City Attorney is a Hyper-V shop (not in the VMware or CrowdStrike feeds); MTA inventory is pending; DA runs a separate CrowdStrike tenant; and other smaller independent shops remain outside this view. One-time inventory exports will replace these with real counts — as just happened for PUC, DPH, and SFO (see citywide footprint below). The 6-month citywide infrastructure survey will establish the complete baseline.

Department-Managed Servers

The 2,875 servers outside the centralized SFCloud stack and approved cloud, split by funding source. Includes self-reported enterprise departments (PUC, DPH, SFO) marked ~. General Fund draws on shared City revenue; non-General-Fund is enterprise or set-aside funded (different migration economics).

General Fund

Funded by shared City revenue

Non-General Fund

--

Enterprise / set-aside funded (DBI, RET, PUC, AIR, MTA, PRT, LIB)

HSA leads the General Fund side (245 servers, own network). On the non-GF side, DPH (~914, Hosting Team only — excludes Facilities/UCSF, so higher), SFO (~540) and PUC (~500) dominate; DBI adds 338 (Permit Tracking System, 226 Windows 7 VDI).
