cloudregion 0.0.2

Simple Python library that converts between cloud region names across AWS/Azure/GCP.

cloudregion

A lightweight Python library for canonical cloud region mapping across AWS, Azure, and Google Cloud Platform.

Tired of remembering that AWS uses us-east-1, Azure uses eastus, and GCP uses us-east1 for the same region? cloudregion provides a simple, consistent interface using intuitive city-based names.

🚀 Quick Start

pip install cloudregion

from cloudregion import region

# Use intuitive city names
r = region('virginia')
print(r.aws)    # us-east-1
print(r.azure)  # eastus
print(r.gcp)    # us-east1

# Works with aliases too
region('us-east').aws   # us-east-1
region('eu-west').gcp   # europe-west1

💡 Why cloudregion?

Multi-cloud developers waste time dealing with inconsistent region naming. Each cloud provider uses different conventions:

Region	AWS	Azure	GCP
US East	us-east-1	eastus	us-east1
US West	us-west-2	westus2	us-west1
EU West	eu-west-1	northeurope	europe-west1

This forces developers to:

• 🔄 Maintain separate region mappings in code
• 🧠 Remember provider-specific names for equivalent regions
• 📝 Update configuration files for each cloud provider
• 🔧 Write cloud-specific code instead of cloud-agnostic code

🎯 Features

• 🏙️ City-based names: Use intuitive names like virginia, tokyo, frankfurt
• 🔄 Multi-cloud: Single interface for AWS, Azure, and GCP
• 🏷️ Smart aliases: us-east, eu-west, asia-southeast work too
• 🧰 SDK integration: Helper functions for boto3, Azure SDK, GCP clients
• ✅ Type safe: Full mypy support with proper type hints
• ⚡ Zero dependencies: Pure Python with no external requirements
• 🧪 Well tested: Comprehensive test suite with 100% coverage

📖 Usage

Basic Usage

from cloudregion import region

# Create region objects
virginia = region('virginia')
tokyo = region('tokyo')
frankfurt = region('frankfurt')

# Access provider-specific names
print(virginia.aws)    # us-east-1
print(tokyo.azure)     # japaneast
print(frankfurt.gcp)   # europe-west3

# Use aliases
us_east = region('us-east')      # resolves to virginia
eu_west = region('eu-west')      # resolves to dublin
asia = region('asia-southeast')  # resolves to singapore

SDK Integration

from cloudregion.integrations import boto3_client_kwargs, azure_credential_kwargs, gcp_client_kwargs

# AWS boto3
import boto3
client_config = boto3_client_kwargs('ec2', 'virginia')
ec2 = boto3.client(**client_config)  # auto-resolves to us-east-1

# Azure
azure_config = azure_credential_kwargs('frankfurt', subscription_id='my-sub')
# Use with Azure SDK clients

# GCP
gcp_config = gcp_client_kwargs('tokyo', project='my-project')
# Use with Google Cloud client libraries

Error Handling

from cloudregion import region, UnknownRegionError

try:
    r = region('unknown-place')
except UnknownRegionError as e:
    print(f"Error: {e}")
    # Error: Unknown region 'unknown-place'. Available regions: virginia, oregon, ...

🔮 Roadmap

• Terraform/Pulumi integration: Generate provider-specific variables
• Compliance zones: EU, US-Gov, China region mappings
• Latency data: Distance and performance metrics between regions
• Service availability: Which services are available in each region
• Cost data: Regional pricing information integration

🙏 Acknowledgments

• Inspired by the need for simpler multi-cloud development
• Built with modern Python tooling (uv, ruff, mypy)
• Tested across Python 3.9-3.13
