Web app naming convention

The CAF abbreviation for Web app is app. Names can be 2 to 60 characters long and allow alphanumerics and hyphens. The name must be globally unique across all of Azure.

Naming rules

CAF abbreviation	app
Length	2 to 60 characters
Allowed characters	Alphanumerics (a-z, A-Z, 0-9), hyphens
Scope of uniqueness	Global (must be unique across all of Azure)
CAF pattern	app-{workload}-{environment}-{region}-{instance}

Worth knowing: Globally unique name.

Rules follow Microsoft's resource naming rules and CAF abbreviations. Some resource types have extra start/end character restrictions, so verify against the official docs before locking in a convention.

Example names

Generated by the same engine as the name generator, so length and character rules are already applied.

Scenario	Generated name	Length
Payments API, production	`app-payments-prod-eus-001`	25/60
Web app, development	`app-webapp-dev-weu-002`	22/60
Analytics with company prefix	`app-contoso-analytics-stage-uks-001`	35/60

Naming in Terraform and Bicep

Build the name from variables so one module produces the right name in every environment.

Terraform

locals {
  web_app_name = "app-${var.workload}-${var.environment}-${var.region}-001"
}

Bicep

var webAppName = 'app-${workload}-${environment}-${region}-001'
