# Terraform: Easier Azure Region Pairing and Governance with the Build5Nines Region Map Module

**[Build5Nines](https://daily.dev/sources/build5nines)** · 10 min read · 0 upvotes · 0 comments

## Summary

Managing Azure regions in Terraform at enterprise scale requires consistent naming abbreviations, paired-region lookups for DR, and allowed-region enforcement. The Build5Nines Terraform Azure Region Map module centralizes this logic, providing region normalization (accepting both 'eastus' and 'East US'), automatic Azure paired-region resolution, short-name abbreviations for resource naming, allowed-region validation, and geography/compliance-zone metadata. The module supports a default paired-region strategy and a custom secondary-region strategy, making it flexible for organizations with specific DR or data-residency requirements. It is open source under the MIT License and published to the Terraform Registry.
