During April 2026, Ykh015 developed the SkuMixPlacement API for the mikeharder/azure-rest-api-specs repository, focusing on optimizing virtual machine SKU mix placement and resource allocation in Azure. Using TypeScript and leveraging expertise in API development and cloud computing, Ykh015 implemented a new Microsoft.Compute/SkuSplit subservice with a singleton resource for mixPlacementScores and a POST endpoint to generate placement scores. The solution supported both explicit VM sizes and VMAttributes, providing flexibility for capacity planning. Automation artifacts such as AutoRest readme and tspconfig were included to streamline documentation and SDK generation, establishing a robust foundation for future Azure SDK enhancements.
