Jul 1, 20252025-07 Monthly Summary for flexera-public/policy_templates focusing on key feature delivery, major bug fixes, and overall impact. Delivered two primary changes: (1) Azure Instance Size Flexibility Ratio Table – introduced a data-driven table to mirror AWS Normal Form Units, wired into the azure_compute_instance_types.py script, fetching and validating ratios from a remote Azure URL, and corrected the invocation to create_instance_size_flexibility_ratio_table. Commits: cf150e75a8dc0bb5bab9c8c345c7d7125fa5fdcb; 4111fc6567c7b7bb95cd244ff85aaf3d47e44f9a. (2) ITAM Policies Cleanup: Removed the ITAM VMs Missing Host ID policy due to accuracy issues, removing the policy template, related changelog, README, and updating CSV/YAML listings to reflect the removal. Commit: 17e7537649c8e7376124d48451ce2b22cddc4b2c. Key business value: improved data fidelity and governance for cloud policy templates, enabling more accurate capacity planning and cost insights for Azure vs AWS. Overall impact: reduced risk from incorrect policy configurations, introduced cross-cloud sizing alignment, and strengthened maintenance hygiene. Top business outcomes: better policy governance, more reliable compute sizing data, and clearer traceability of changes.

Mar 1, 2025Summary for 2025-03: In flexera-public/policy_templates, delivered high-impact fixes and stability improvements around memory metrics and Azure policy authentication, improving accuracy, security posture, and policy reliability. Key work includes memory statistics display bug fix for Azure compute memory usage (now shows percentage, e.g., 31%), Entra OAuth authentication support for Azure Blob policy via x-ms-version header (policy version 0.1.1), rightsizing policy memory calculation bug fix correcting average available memory calculation (version 6.1.2), and changelog/documentation improvements clarifying memory metrics. These changes reduce operator confusion, improve decision quality for resource sizing, and strengthen policy interoperability with Azure authentication flows. The changes are tied to commits aefd7068af88212e55d86f4ee96029d6f1fb1827, 2e12e71120205e93cf537ae77ce2f5ec15e749aa, 09867e9c4575175138ec5ec000cd98d159336556, fccca913acae5da31abc0b5b09b2c6ac3ca529f4, b596b7394ab04b9e249239e07e50bd87705af054, b44f8acc4b8cc850b101014f079130c12de24a10.
