# Cloud Overview

The Nx AI Cloud platform lets you:

* **Manage AI models:** see which models are available to your account, track versions of your own models, and convert uploaded models for edge deployment. See [Upload your model](/nx-ai-manager-v6.1.2/nx-ai-cloud-ui/upload-your-model.md).
* **Deploy models to edge devices:** assign or swap model pipelines on any device remotely. Group devices and push a pipeline change to all of them at once.

The diagram below shows how model sources, the cloud platform, and edge devices relate.

## Key concepts

Understanding the following terms helps explain how models, devices, and access control relate to each other in the Nx AI Cloud platform:

* **Site:** An installation of one or more Nx Servers registered to your cloud account. Sites appear in the Sites tab and can be online or offline.
* **Server:** An individual Nx Mediaserver process running inside a site. A site can have multiple servers; each server hosts a set of devices.
* **Device:** A camera or other input source connected to a server. AI pipelines are assigned and run per device.
* **Organization:** A grouping of sites and users for access control. Models and catalogues must be connected to an organization for the devices in that organization to see them.
* **Catalogue:** A named collection of AI models. Catalogues are assigned to organizations to control which models are available to which sites.
* **Pipeline:** One or more chained AI models assigned to a specific device, defining what runs on that device's video stream.

{% hint style="info" %}
If a custom model is not visible when assigning it to a device, the most common cause is that the model's catalogue is not connected to the organization that owns the site. See [Upload your model](/nx-ai-manager-v6.1.2/nx-ai-cloud-ui/upload-your-model.md) for details on setting this up.

### Accessing the Nx AI Cloud interface

The Nx AI Cloud admin interface is a web application. After logging in with your Nx account, you can manage your models and devices from any browser.
