1. Introduction
Purpose, audience, and context of the methodology.
Greenpixie publishes a region scorecard that describes each cloud region offered by the providers in scope. This document sets out how two of the scores on that scorecard are produced, the pricing score and the coverage score.
The pricing score records whether a region is expensive or inexpensive compared with the middle of that provider's own estate. The score is published as a percentage difference from the median region, so a value of minus eight per cent describes a region whose catalogue prices are around eight per cent below the median for that provider, together with a grade from 1 to 5 in which 1 is the least expensive band.
The coverage score measures how much of the provider's catalogue a customer can actually buy in that region. Greenpixie publishes it as a percentage of the catalogue held by the provider's most complete region, so a value of eighty per cent describes a region that prices four fifths of the products the leading region prices, together with a grade from 1 to 5 in which 1 is the most complete band.
Both scores are derived from prices as published by the provider. Neither score contains an estimated component, and no customer usage or spend data is used at any point. Each provider is scored within its own estate, so a score for a region of one provider carries no comparison with a region of another. A grade of 4 on one provider does not describe the same premium as a grade of 4 on another, and the document returns to that constraint in Section 11.
The document is written for customers, auditors, and procurement teams who want to understand what the two scores measure, what they exclude, and how far they can be relied on.
