# Deployment modes

The OE stack supports two deployment modes, determined by whether the dataspace uses SSI‑based access control.

## Dataspace with SSI-based access control disabled

### Configuration example

In a dataspace where SSI‑based access control is disabled, only two OE components are required: the OE Node and the marketplace. The table below provides the assumed URLs for each element.

| Component   | URL                                 |
| ----------- | ----------------------------------- |
| OE Node     | <https://node.oceanenterprise.io>   |
| Marketplace | <https://market.oceaneneteprise.io> |

To ensure correct operation, configure the relevant environment variable in each component, using the examples shown in the table below.

| Component       | Environment variable                                                                                                            | Value                             |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------- | --------------------------------- |
| **OE Node**     | [POLICY\_SERVER\_URL](/infrastructure/oe-node-installation-and-configuration.md#policy_server_url)                              | null                              |
| **Marketplace** | [NEXT\_PUBLIC\_PROVIDER\_URL](/infrastructure/marketplace-installation-and-configuration.md#next_public_provider_url)           | <https://node.oceanenterprise.io> |
|                 | [NEXT\_PUBLIC\_METADATACACHE\_URI](/infrastructure/marketplace-installation-and-configuration.md#next_public_metadatacache_uri) | <https://node.oceanenterprise.io> |
|                 | [NEXT\_PUBLIC\_SSI\_ENABLED](/infrastructure/marketplace-installation-and-configuration.md#next_public_ssi_enabled)             | false                             |

### Installation sequence

The recommended deployment order for this setup is:

1. [Install and configure the OE Node](/infrastructure/oe-node-installation-and-configuration.md)
2. [Install and configure the marketplace](/infrastructure/marketplace-installation-and-configuration.md)

## Dataspace with SSI-based access control enabled

### Configuration example

In a dataspace with SSI‑based access control enabled, all OE components are required. The table below provides the assumed URLs for each element.

| Component           | URL                                   |
| ------------------- | ------------------------------------- |
| OE Node             | <https://node.oceanenterprise.io>     |
| Marketplace         | <https://market.oceaneneteprise.io>   |
| Policy Server       | <https://ps.oceanenterprise.io>       |
| Policy Server Proxy | <https://proxy.oceanenterprise.io>    |
| SSI Wallet          | <https://wallet.oceanenterprise.io>   |
| Verifier            | <https://verifier.oceanenterprise.io> |
| OPA Server          | <http://opa.oceanenterprise.io:8181>  |

To ensure correct operation, configure the relevant environment variable in each component, using the examples shown in the table below.

| Component               | Environment variable                                                                                                                                                         | Value                                         |
