Worked on enhancing the prefapp/tfm repository by improving the Azure Windows VM module, focusing on both configuration simplification and feature expansion. Used Terraform and HCL to remove redundant parameters such as osdisk and os_managed_disk_id, streamlining the deployment process and reducing potential configuration errors. Added support for Ultra SSD storage and VM hibernation, enabling more flexible and performant Azure Windows workloads. Updated documentation and configuration files in Markdown and Terraform to ensure alignment with the new capabilities. The work demonstrated a methodical approach to infrastructure as code, emphasizing clarity, maintainability, and the adoption of advanced Azure features for Windows environments.
