On-Premise vs Cloud-Hosted Clinical Infrastructure
TL;DR

  • The on-prem vs cloud decision for clinical infrastructure is not a technology decision delegated to IT. It is a multi-year capital and operating decision with HIPAA, vendor risk, and business continuity implications the CFO should size.

  • A defensible CFO framework evaluates each option on capital structure, operating cost trajectory, HIPAA program implications, business continuity capability, and migration cost over the cycle.

  • The CFO question is not which is better in the abstract. It is which fits the organization's capital posture, operating model, and risk profile across the multi-year cycle.

 

The Five Dimensions a Cloud vs. On-Prem Decision Actually Requires

  1. Capital structure: on-prem requires capital; cloud is operating expense.

  2. Operating cost trajectory: long-term curves differ.

  3. HIPAA program implications: BAA structure, configuration, audit logging.

  4. Business continuity capability: recovery posture differs.

  5. Migration cost if changing later.

 

Why "Cloud Is Cheaper" Rarely Holds Without the Specifics

A CFO will hear: cloud is cheaper, the technology team prefers cloud.

Rarely accurate without specifics.

 

The Structured Evaluation That Makes the Infrastructure Decision Defensible

A defensible approach involves healthcare CFO through structured infrastructure decision evaluation.
