P069: Prompt, context and policy management: Google Cloud study

Abstract

Prompt, context and policy management: Google Cloud study Author: Sonu Kumar Singh (Senior Consultant — Cloud & AI Solutions Architecture, Capgemini US LLC) Professional Credential: Member, IEEE (Membership # 102728576) | ORCID: 0009-0002-9180-4946 Abstract Enterprise generative AI becomes dependable only when retrieval, tools, identity, policy, provenance, evaluation, and human oversight are engineered as a system around the model. Against this backdrop, the paper examines prompt, context and policy management in Google Cloud. It asks a focused question: How should prompt, context and policy management be designed, governed, and empirically evaluated for Google Cloud? To keep the discussion testable, prompt, context and policy management is defined in operational terms. The paper focuses on the points where architecture choices become visible in behavior—how data is represented, how policies are enforced, how workloads fail and recover, and what evidence is left behind. That boundary is intentionally narrower than a feature survey and broad enough to capture the system-level trade-offs. The paper contributes a decision framework and a validation plan. It connects architecture to governance, reliability, cost, and measurable evidence, and it uses controlled benchmark and statistical evaluation as the primary research method. Where no experiment has been run, the paper says so directly and specifies what would have to be measured before an empirical conclusion could be defended.
