Developed the DiskPlacementType configuration capability for Azure Virtual Machines within the microsoft/lisa repository, enabling users to specify granular placement options for ephemeral OS disks. This work involved updating ARM and Bicep templates to expose the new setting and extending Python deployment logic to support multiple disk placement scenarios. By integrating Infrastructure as Code practices with Azure cloud technologies, the solution allows for targeted performance tuning and reduces operational risk during VM deployments. The feature enhances deployment flexibility for cloud workloads, demonstrating a strong command of Azure, Bicep, and Python development while addressing practical needs in cloud infrastructure management and automation.
