Cloud service negotiation: a research report
Bibliographic record
Abstract
As the cloud market becomes more open and competitive, Quality of Service (QoS) will be more important. To allow cloud consumers to express their QoS requirements, and negotiate them with cloud providers, we argue for cloud service negotiation. This paper outlines a research roadmap, reviews the state of the art and reports our work on cloud service negotiation. Three research problems that we formulate are QoS measurement, QoS negotiation and QoS assurance. To address QoS measurement, we initiate a quality model for cloud services, called CLOUDQUAL, which specifies six quality dimensions and five quality metrics. To address QoS negotiation, we present a mixed negotiation approach for cloud services, which is based on the ‘game of chicken’ and can balance utility and success rate. To address QoS assurance, we propose a QoS-driven resource allocation method for cloud services, which can meet users’ QoS requirements while minimising resources consumed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
