126_Get-AzAppServicePlanDensity.ps1

<#
.SYNOPSIS
    Calculates the density of App Services running per App Service Plan.

.DESCRIPTION
    App Service Plans (ASP) are the billing unit.
    If you have many ASPs with only 1 App each, you are paying for unused compute.
    This script finds ASPs with low density (e.g. < 2 apps) to suggest consolidation.
