Cloud Region Comparison
Interactive reference table comparing AWS, Azure, and GCP regions with side-by-side region codes, availability zones, and latency estimates.
About This Tool
The Cloud Region Comparison tool is a free, interactive reference for
comparing cloud provider regions across Amazon Web Services (AWS),
Microsoft Azure, and Google Cloud Platform (GCP). It displays region
codes side by side so you can instantly find the equivalent region
across providers — for example, AWS us-east-1 corresponds to Azure
eastus and GCP us-east1.
The tool covers 35+ global locations across six continents, showing availability zone counts, service availability indicators, and latency estimates from a US East baseline. You can search by location name, country, city, or region code, and filter by provider, continent, or specific service categories like Compute, Storage, Database, AI/ML, Analytics, Networking, and IoT.
Two view modes are available: a detailed table view for precise comparison, and a continent-grouped map layout for geographic visualization. Region codes are clickable for instant copying to your clipboard — useful when configuring infrastructure-as-code tools like Terraform or CloudFormation.
If you are working with network infrastructure, the Subnet Calculator can help you plan IP address allocation for your cloud VPCs. For DNS setup across providers, the DNS Record Generator assists with zone file creation. And if you need to format configuration data, the JSON Formatter is handy for cleaning up cloud API responses.
All data is embedded in the page and processed entirely in your browser. No API calls are made and no data is sent to any server, making this tool safe to use in any environment.
How to Use
- Open the tool and browse the full list of cloud regions in the default table view.
- Use the search bar to find regions by typing a location name, country code, city, or provider region code (e.g., "us-east-1", "Tokyo", "DE").
- Toggle provider buttons (AWS, Azure, GCP) to show or hide specific cloud providers from the comparison.
- Select a continent from the dropdown to focus on a specific geographic area.
- Choose a service category (Compute, AI/ML, etc.) to filter regions that offer that service.
- Switch to Map view to see regions grouped by continent in a visual card layout.
- Click any region code to copy it to your clipboard. A "copied" confirmation appears next to the code.

FAQ
How accurate is the region data?
The region data is curated from official AWS, Azure, and GCP documentation as of early 2026. Cloud providers frequently add new regions and services, so some recently launched regions may not be listed yet. The region codes and availability zone counts reflect generally available regions.
What do the latency estimates mean?
Latency estimates are approximate inter-region latencies measured from US East (Virginia) as a baseline. 'Low' means under 50ms (typically same-continent regions), 'Medium' means 50-150ms (cross-continent but well-connected), and 'High' means over 150ms (distant regions like Africa from US East). Actual latency varies by provider, network path, and time of day.
Can I compare equivalent regions across providers?
Yes. Each row in the table represents a geographic location and shows the corresponding region code for each provider that has a data center there. For example, the Tokyo row shows AWS ap-northeast-1, Azure japaneast, and GCP asia-northeast1 side by side.
What are availability zones?
Availability Zones (AZs) are isolated data center groups within a region, each with independent power, cooling, and networking. More AZs in a region means more options for high-availability and fault-tolerant deployments. AWS typically offers 3-6 AZs per region, while Azure and GCP generally offer 3.
Is my data safe?
Yes. This is a purely client-side reference tool. All region data is embedded directly in the page — no API calls are made and no data is sent to any server. You can verify this by checking the Network tab in your browser's developer tools.
Why are some regions missing for certain providers?
Not all providers have data centers in every location. A '--' indicator means that provider does not have a region in that geographic location. You can filter by provider to see only locations where your chosen providers operate.
How do I use these region codes?
Region codes are used in cloud provider CLIs, SDKs, and infrastructure-as-code tools. For example, in AWS CLI you might use '--region us-east-1', in Azure CLI '--location eastus', and in gcloud '--region us-east1'. Click any region code in the table to copy it to your clipboard.
