Defaults Reference

Version 3.7.8 | Single source of truth for regions, naming, tags, and SKUs

This document centralizes all default configuration values for Agentic InfraOps. All other documentation and agent files should reference this document rather than duplicating content.

Default Regions

Region Selection Guidelines

📖 Full guidance: See ADR-004: Region Defaults

CAF Naming Conventions

Follow Cloud Adoption Framework pattern: {type}-{workload}-{env}-{region}-{instance}

Region Abbreviations

Resource Type Prefixes

Name Length Constraints

⚠️ Critical: These resources have strict length limits that cause deployment failures if exceeded.

Unique Suffix Pattern

Generate unique suffixes in main.bicep and pass to all modules:

// main.bicep - Generate suffix once
var uniqueSuffix = uniqueString(resourceGroup().id)

// Pass to all modules
module keyVault 'modules/key-vault.bicep' = {
  params: {
    uniqueSuffix: uniqueSuffix
  }
}

// modules/key-vault.bicep - Apply to resource names
param uniqueSuffix string
var keyVaultName = 'kv-${take(replace(projectName, '-', ''), 8)}-${take(environment, 3)}-${take(uniqueSuffix, 6)}'
// Result: "kv-contosop-dev-abc123" (22 chars, within 24 limit)

Required Tags

All Azure resources MUST include these tags:

Bicep Tag Pattern

var tags = {
  Environment: environment
  ManagedBy: 'Bicep'
  Project: projectName
  Owner: owner
  CostCenter: costCenter
  DeploymentDate: utcNow('yyyy-MM-dd')
}

SKU Recommendations

By Environment

Zone Redundancy Requirements

⚠️ App Service Plans: Must use P1v4 or higher for zone redundancy. Standard SKU (S1/S2/S3) does NOT support zone redundancy.

Azure Verified Modules (AVM)

Always prefer AVM modules over raw Bicep resources.

AVM Registry

• Registry: br/public:avm/res/*
• Documentation: https://aka.ms/avm
• Module Index: https://aka.ms/avm/index

Common AVM Modules

📖 Full guidance: See ADR-003: AVM-First Approach

Security Baseline

All resources should follow these security principles:

Common Azure Policy Requirements
