About

This tool automates the creation of Azure Resource Names strictly adhering to the Microsoft Cloud Adoption Framework (CAF). Naming resources in the cloud is not merely aesthetic; it is a critical governance practice. Inconsistent naming leads to resource conflicts, security ambiguity, and deployment failures.

Unlike simple string concatenators, this generator implements the specific validation logic for each Azure resource type. For instance, a Storage Account is limited to 24 characters with no hyphens, while a Virtual Machine allows up to 64 characters with hyphens. We handle these edge cases automatically using the official abbreviation standards.

Formulas

The standard naming pattern follows the Scope-Specific format defined by Microsoft:

Name = Resource + App + Env + Region + Instance

However, specific constraints apply conditionally:

{
Standard: res-app-env-loc-##Storage/ACR: lowercase(resappenvloc##)
Where:
res = Resource Type Abbreviation
app = Workload/Application Name
env = Environment (dev, prod, stg)
loc = Azure Region (e.g., weu, eus)
## = Instance Number (001, 002)

Frequently Asked Questions

Azure Storage Accounts must have globally unique DNS names (e.g., mystorage.blob.core.windows.net). The DNS standard used by Azure for these legacy endpoints supports only lowercase letters and numbers to ensure compatibility and prevent ambiguity across the global namespace.
It varies significantly. Virtual Machines allow 64 characters, while Storage Accounts allow only 24. Key Vaults are also restricted to 24. This tool automatically validates your input against the specific limit for the selected resource type.
This tool uses the official Microsoft Cloud Adoption Framework (CAF) abbreviations by default. While you can type custom values into the text fields, the "Resource Type" selector will populate the standard prefix (e.g., "vm", "st", 'kv') to ensure compliance.
It is best practice to shorten regions to reduce character count. Common mappings include: West Europe -> "weu", East US -> "eus", North Europe -> "neu", UK South -> "uks".
The tool will display a visual error. You must shorten the variable components (Application Name or Project Code) to fit. For strictly limited resources like Storage Accounts, prioritize conciseness over descriptiveness.
