# Clouds

> Where the engine runs: your AWS, Azure or Google Cloud account, your own servers, or Atlantic-hosted.

The engine runs where you choose: in your own AWS, Azure or Google Cloud account, on your own servers with Docker, or in a dedicated account Atlantic runs for you. LightHouse is the same in every case.

## Choosing where it runs

In LightHouse, **Setup and admin → Where agents run** (`client_admin`): choose the cloud, the region and the [deployment profile](/concepts/deployment-profiles/). LightHouse shows the estimated saving of ephemeral against always-on, then:

- **for your own cloud or servers**, gives you the files to apply: a bootstrap that creates the identity your pipeline deploys with, and the stack itself as Terraform (Compose on your own servers). **Your own pipeline applies them, as a reviewed merge request. LightHouse never applies infrastructure in your account**, and the bootstrap grants Atlantic no access to it;
- **for Atlantic-hosted**, records your request for Atlantic to review. See [Atlantic-hosted](/clouds/atlantic-hosted/).

Changing your choice later moves nothing: the old deployment keeps running until your own pipeline takes it down.

The same choice by API: `GET` and `PUT /api/v1/run-targets`, and `GET /api/v1/run-targets/stack` for the files. See the [Read reference](/api/reference/read/#get-targets).

## What is the same everywhere

- The engine’s components: the gateway, the orchestrator and jobs, the telemetry relay, the content reader and the command channel.
- The [telemetry contract](/concepts/telemetry-contract/): counts and timings to LightHouse, never content.
- Every component dials out to LightHouse over HTTPS; nothing in your account listens for Atlantic.
- Your content, your index and your model calls stay in your account and region. See [Data sovereignty](/data-sovereignty/).
- The stack is a pinned, tagged version of Atlantic’s infrastructure modules, upgraded by a reviewed change. See [Upgrades](/operations/upgrades/).

The first region listed is LightHouse’s default. Savings are for a small deployment at list prices in the first region, and are **estimated**: see [Deployment profiles](/concepts/deployment-profiles/#estimated-savings-against-always-on).
