The Guidewire Cloud Platform (GWCP) enforces a rigorous and standardized path for code promotion to ensure maximum stability in production environments. This process follows the Astronomy Metaphor where code moves between logical partitions.
Statement C is a fundamental truth of the cloud delivery model: Sequential Promotion. Code cannot " skip " environments. A build must first be verified in the Development Star System (on a Dev planet). Once verified, that same immutable build (Docker image) is promoted to the Pre-Production Star System for User Acceptance Testing (UAT) and Performance testing. Only after passing the " Quality Gates " in Pre-Prod can the build be promoted to the Production Star System. This sequence ensures that the exact same code being deployed to production has been thoroughly vetted in lower environments.
Statement E identifies the tool used for this management: the Build Promotion app located in Guidewire Home. This application provides a centralized interface for authorized users to select a verified build from a lower " Orbit " and promote it to a higher one. This tool abstracts the underlying complexity of the CI/CD pipeline and ensures that the promotion follows all security and compliance protocols.
Option D is incorrect because code is never " committed " directly to production; rather, a pre-compiled build image is promoted. Option B is incorrect as not every dev planet needs a deployment-only the specific verified " golden " build needs to move forward. Adhering to this sequential, tool-managed process is a key requirement of the Guidewire Cloud Standards.
