Clouds

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. 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.

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.

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: 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.
• The stack is a pinned, tagged version of Atlantic’s infrastructure modules, upgraded by a reviewed change. See Upgrades.
