## How it works

> **Note**: Unlike AWS and Azure, GCP requires deploying Grafana Alloy. There is no serverless “scrape job” option.

**Complexity:** Moderate | **Infrastructure:** GCE or GKE | **Latency:** Configurable

## Authentication options

| Authentication                 | Description                         |
|--------------------------------|-------------------------------------|
| **Service account (JSON key)** | Simple setup, requires key rotation |
| **Workload identity**          | No keys to manage, more secure      |

## Trade-offs

| Pros                         | Cons                       |
|------------------------------|----------------------------|
| Multi-project from one agent | Deploy and manage Alloy    |
| Workload identity option     | Infrastructure to maintain |
| Full processing pipeline     |                            |
| Converts to PromQL           |                            |
