# Multi-Region Deployment

> Deploy your apps globally across multiple regions for improved latency and data residency compliance

Cerebrium's multi-region deployment capability allows you to deploy your apps globally across different continents, taking advantage of co-location for reduced latency and meeting data residency requirements.

<Warning>
  Multi-region deployment is currently in **beta**. Rapid updates and
  improvements will be made over the next few months to bring full functionality
  to life. Please reach out on our [Discord](https://discord.gg/ATj6USmeE2)
  about features/functionality you would like to see
</Warning>

## Why Use Multi-Region Deployment

* **Reduced Latency**: Deploy closer to users for faster response times and better experience with real-time applications like voice agents and LLMs
* **Data Residency**: Meet data protection requirements by keeping sensitive data within specific geographic regions to comply with regulations like GDPR and CCPA
* **High Availability**: Ensure fault tolerance and continuous service through geographic redundancy, disaster recovery, and load balancing across multiple regions

## Available Regions

Cerebrium supports deployment across three major continents with the following regions:

### United States

* **us-east-1** (N. Virginia) - Default region

### Europe

* **eu-west-2** (United Kingdom)

### Asia Pacific

* **ap-south-1** (India) - Coming soon

<Info>
  Additional regions are being evaluated and will be added based on user demand
  and infrastructure availability. Contact
  [support](mailto:support@cerebrium.ai) if you need deployment in a specific
  region not currently listed.
</Info>

## CLI Configuration

You can configure your CLI to work with different regions in two ways:

Set a default region for your CLI sessions that will be used for all commands:

```bash theme={null}
cerebrium region set us-east-1
```

This will set the default region for commands like listing storage volumes, running applications, and other operations.

Alternatively, you can specify the region for individual commands using the `--region` flag:

```bash theme={null}
# List storage volumes in a specific region
cerebrium ls --region eu-west-2

```

<Info>
  The `--region` flag takes precedence over the default region set with
  `cerebrium region set`. This allows you to temporarily use a different region
  without changing your default configuration.
</Info>

## App Deployment

Configure your app's deployment region using the `region` parameter in the `[cerebrium.hardware]` section of your `cerebrium.toml` file:

```toml theme={null}
[cerebrium.hardware]
region = "us-east-1"
provider = "aws"
compute = "AMPERE_A10"
cpu = 2
memory = 8.0
```

## Pricing

Pricing varies by region based on local infrastructure costs and availability:

## GPU Availability by Region

GPU availability and pricing vary across regions due to infrastructure constraints and local demand:

| GPU Model          | US East | EU West | AP South |
| ------------------ | ------- | ------- | -------- |
| HOPPER\_H100       | ✅       | ✅       | ✅        |
| AMPERE\_A100\_40GB | ✅       | ✅       | ✅        |
| ADA\_L40S          | ✅       | ❌       | ❌        |
| ADA\_L4            | ✅       | ✅       | ✅        |
| AMPERE\_A10        | ✅       | ✅       | ✅        |
| TURING\_T4         | ✅       | ✅       | ✅        |

### Limitations

* Each region requires a separate deployment. Apps deployed in one region do not automatically replicate to other regions.
* Each region has its own isolated persistent storage volume. Data stored in `/persistent-storage` in one region is not accessible
  from other regions.
