Overview of the deployment models, upon which Unique can be run.

---

Unique _for Enterprises_ comes basically in four layers that stack onto each other. All these layers are part of the regular release cycle as seen in [Upgrade and Release Process](https://docs.unique.ai/it-operators/installing-and-upgrading-unique/upgrade-and-release-process), but it depends on the Deployment Model from which of all layers the client profits or leverages.

For each of them you can find further documentation below.

| **Layer** | **Documentation** | **Content** |
|------------|------------------|-------------|
| **1**      | [Install Unique](https://docs.unique.ai/it-operators/installing-and-upgrading-unique/install-unique) | The setup and run of these 3 layers depend on the deployment model chosen. Read more in the models you are interested in about their details. |
| **2**      |                  |             |
| **3**      |                  |             |
| **4**      | [Architecture Overview](https://docs.unique.ai/administrators/architecture-overview) | The Product itself is (besides configuration of course) always the same on all models and is explained in Architecture.
