An opinionated region and abbreviation helper for enterprise multi-region Terraform deployments.
Problem it solves: Multi-region Terraform gets messy fast — primary/secondary regions, short codes, paired regions, allowed regions, data-residency zones, and naming abbreviations. This module wraps all of that into a single, enterprise-focused interface so you can stop hand-coding region lookups and focus on infrastructure.
Features
- Automatic paired-region resolution — Looks up Azure’s designated regional pair for any primary region.
- Flexible secondary region strategy — Use the Azure pair or specify a custom secondary region.
- Built-in abbreviations — Short codes for 60+ Azure regions (e.g.
eastus→eus), with override support. - Display name resolution — Maps canonical names to human-readable display names (e.g.
eastus→East US). - Policy compliance gating — Define an allow-list of approved regions and check deployments against it.
- Geography & compliance zone metadata — Know each region’s geography (e.g.
United States,Europe) and compliance zone (Americas,EMEA,Asia Pacific). - Cross-geography / cross-zone flags — Instantly determine if your primary and secondary regions span geographies or compliance zones for DR and data-residency decisions.
- Input normalization — Accepts both canonical names (
eastus) and display names (East US). - No providers required — Pure Terraform logic with local JSON data; no API calls, no credentials needed.
