# Claude Code in Vertex, Bedrock

Configure Claude Code in Nimbalyst to run through Google Vertex AI or Amazon Bedrock using your own cloud account and existing credentials.

Nimbalyst can run Claude through your preferred cloud provider, Claude on Vertex AI (Google Cloud) or Amazon Bedrock, instead of Anthropic directly. Use this when your organization already has cloud billing and compliance set up with one of those providers.

You configure this by adding environment variables in the Claude Agent settings panel. Nimbalyst sets them for the Claude Code sessions it launches; they are stored with your Claude Code settings, and Nimbalyst never reads API keys from your shell environment.

### How to configure

1. Open **Settings > Application > Claude Agent**.
2. Scroll to the **Environment Variables** section.
3. Add the required variables for your provider.

**For Google Vertex AI:**

| Variable                      | Value                                           |
| ----------------------------- | ----------------------------------------------- |
| `CLAUDE_CODE_USE_VERTEX`      | `1`                                             |
| `CLOUD_ML_REGION`             | `global` (or a specific region like `us-east5`) |
| `ANTHROPIC_VERTEX_PROJECT_ID` | Your GCP project ID                             |

Prerequisites: Enable the Vertex AI API in your GCP project, request access to Claude models in the Model Garden, and authenticate via `gcloud auth application-default login`.

**For Amazon Bedrock:**

| Variable                  | Value                                  |
| ------------------------- | -------------------------------------- |
| `CLAUDE_CODE_USE_BEDROCK` | `1`                                    |
| `AWS_REGION`              | `us-east-1` (or your preferred region) |

Prerequisites: Enable Bedrock access in your AWS account, request access to Claude models, and configure AWS credentials (via AWS CLI, environment variables, or SSO profile).

### Benefits

* Use existing cloud credentials and billing
* Meet enterprise compliance requirements
* Choose the provider that fits your infrastructure
* No separate Anthropic API key required
