Bias Analysis

Bias Types:
⚠️ powershell_heavy
⚠️ missing_linux_example
⚠️ windows_tools
⚠️ windows_first
Summary:
The documentation is heavily biased towards Windows and PowerShell. All examples use Azure PowerShell cmdlets, with no mention of Azure CLI, Bash, or Linux-based workflows. The VM creation steps specifically use Windows Server images, and the only remote access method shown is RDP (port 3389), which is Windows-specific. There are no Linux VM examples, nor are there instructions for SSH or Linux image deployment. The documentation assumes the user is working in a Windows/PowerShell environment throughout.
Recommendations:
  • Provide parallel examples using Azure CLI (az commands) and Bash scripts for all resource creation steps.
  • Include Linux VM deployment examples (e.g., using Ubuntu or CentOS images) alongside or instead of Windows Server.
  • Show how to configure SSH access (port 22) in the network security group rules, not just RDP.
  • Explicitly mention that the steps can be performed from Linux/macOS using Azure CLI or Cloud Shell, and provide relevant instructions.
  • Reorganize the documentation to present cross-platform options equally, rather than focusing exclusively on PowerShell/Windows.
  • Add a section or callout for Linux users, highlighting any differences or considerations.
