On-Prem Sizing Toolkit (Preview)
Quick sizing estimates for common on-prem server workloads (AD DS, RDS, SQL, MECM, WSUS, etc.) using a practical rule-based model. Always validate with real monitoring before production decisions.

Assumptions & Notes
Module assumptions + validation checklist.
Assumptions
Validation Checklist
- Confirm CPU peak during the real spike window (PerfMon / Hypervisor metrics).
- Check storage latency on OS/DATA/LOG/TEMPDB (where applicable).
- Validate concurrency and burst behavior (logon storms, patch windows, reports).
- Include N+1 capacity for maintenance and unexpected surges.

Tip: For bursty environments (e.g., 10,000 logons in 10 minutes), prefer scale-out (more nodes) vs.
oversized single servers.
