Decision Axes Framework

Evaluating the trade-offs between Local Intelligence and Cloud APIs.

> EXEC_SUMMARY

The choice to run on-premise is rarely about "performance" alone. It is a strategic decision balancing Privacy Risk, Capital Expenditure, and Operational Complexity.

Use this framework to visualize where your organization sits on the spectrum.

01. Security & Privacy

Cloud API

  • Contractual Trust (SOC2, HIPAA)
  • Data traverses public internet
  • Provider *can* see data (unless Zero Access)
TRUST BOUNDARY

On-Premise

  • Physical Trust (Air-Gapped)
  • Data stays on owned metal
  • Zero leakage risk by design

02. Total Cost of Ownership (TCO)

Cloud API

  • Opex (Operating Expense)
  • Pay per Token
  • Scales linearly with usage
  • Best for: Spiky/Low volume
CAPEX vs OPEX

On-Premise

  • Capex (Capital Expense)
  • Pay for Silicon + Energy
  • Near-zero marginal cost per token
  • Best for: 24/7 heavy volume

03. Reliability & Control

Cloud API

  • Forced Deprecations
  • Model Weight Changes
  • Rate Limits / Service Outages
SYSTEM SOVEREIGNTY

On-Premise

  • Frozen Weights (Forever Version)
  • No Rate Limits
  • Full uptime control

04. Talent Requirement

Cloud API

  • Software Engineering
  • REST API Integration
  • Low Friction
OPERATIONAL DRAG

On-Premise

  • ML Ops / DevOps
  • CUDA / Hardware Debugging
  • High Friction
