Region Pricing

I. Formal Definition

The variation in per-unit price for the same cloud service across different geographic regions, driven by local cost structure, regulatory load, and provider commercial strategy. Region pricing creates a procurement lever where workload placement is flexible and a constraint where data residency or latency rules apply. The federation requires the regional placement decision for each Tier-1 service to be documented with the cost, latency, and compliance considerations and reviewed at the annual architecture review under UFMS-001:2.4(d). Cross-region price drift is monitored quarterly.

II. Etymology

A construction of cloud provider pricing literature; the AWS region price differential drew the term into general FinOps vocabulary in the mid 2010s.

III. Federation Usage

Federation members document regional placement for each Tier-1 service. Cross-region price drift is monitored quarterly with significant divergences triggering an architecture review under MEV-Annex:3.2. Compliance constraints on placement are recorded in the data residency register.
