How It Works
This Azure RG Owner Review script is like a sous-chef that does the heavy lifting—turning a once-arduous, enterprise-only process into a breezy, reliable workflow anyone can adopt. We’ve kept things simple in the kitchen and focused on serving up governance reports that application owners actually look forward to.
First off, authentication is as easy as running Connect-AzAccount. Whether you’re testing interactively or deploying via a service principal, you’ll skip the managed identity gymnastics and still cook securely with Azure’s tried-and-true login methods.
Once you’re in, the script goes through every Azure subscription you’ve got access to, hunting down Resource Groups that have been tagged with Application-Name. Think of that tag as the recipe card that tells our script which “dish” (application) each Resource Group belongs to. From there, we gather all the RG ingredients and group them together, so you can keep tabs on each application’s entire infrastructure with just one tidy report.
In short: no extra drama, no arcane setups—just a lean, mean, governance machine that keeps everyone accountable and your cloud kitchen running smoothly.
Simplified Tag Schema
The script relies on three straightforward tags that any organization can implement:
The grouping algorithm processes each resource group by extracting the Application-Name tag value, creating logical application boundaries that span across subscriptions and resource groups. This application-centric approach provides owners with a comprehensive view of their infrastructure footprint, regardless of how resources are distributed across the Azure estate.
Email delivery operates directly from the Owner tag value, eliminating the need for user directory lookups or complex user resolution processes. The script validates that the Owner tag contains a properly formatted email address and falls back to a configurable default email when the owner information is missing or invalid.
The resource inventory phase involves detailed enumeration of all resources within each resource group belonging to an application. The script captures resource names and types, presenting this information in a visually appealing HTML format that helps owners understand their current infrastructure composition and identify optimization opportunities.
Email generation represents the culmination of the process, where the script transforms raw resource data into professionally styled HTML reports featuring CloudCostChefs branding and chef-themed messaging. Each email is personalized for the specific application owner and includes contextual information about resource accountability and cost management best practices.
The simplified architecture processes large Azure environments efficiently by eliminating external API dependencies and complex authentication flows. The script can handle hundreds of subscriptions and thousands of resource groups while maintaining fast execution times and reliable email delivery.
Prerequisites
The simplified Azure Resource Group Owner Review script has minimal prerequisites compared to enterprise-grade solutions, making it accessible to organizations of all sizes while maintaining professional functionality. The streamlined requirements focus on essential Azure services and basic infrastructure components that most organizations already have in place.
Azure Services and Components
The following Azure services and components are required:
Azure PowerShell Modules
The script requires only two PowerShell modules:
- Az.Accounts: Provides Azure authentication and context management
- Az.Resources: Enables resource group and resource enumeration
No Microsoft Graph modules or complex dependencies required
Azure Permissions
The executing account requires minimal permissions:
- Reader role: At subscription or management group level for resource discovery
- No special permissions: No Microsoft Graph API permissions needed
