+# Persistent (Long-Running) Server
+
+Genezio supports deploying persistent or long-running servers, ensuring that your application remains active without scaling down to zero.
+This is particularly useful for applications that require continuous processing or stateful operations.
+
+
+## What is a Persistent Server?
+
+A persistent or long-running server is an application that stays active and does not automatically scale down to zero when there are no incoming requests.
+Unlike serverless functions that are event-driven and ephemeral, persistent servers allow for stateful operations and long-running tasks.
+
+## Deploy Persistent Server in Genezio
+
+To deploy a persistent server on Genezio, you need to define the function type as persistent in your genezio.yaml configuration file.
+
+Here's an example of a genezio.yaml configuration file with a persistent function:
+
+```yaml
+name: my-project
+region: us-east-1
+yamlVersion: 2
+backend:
+  path: .
+  language:
+    name: js
+  functions:
+    - name: persistent-server
+      path: .
+      entry: server.mjs
+      handler: handler
+      type: persistent
+```
+
+Once you have configured the `genezio.yaml` file, you can either commit it to your GitHub repository or deploy it directly using the Genezio CLI:
+
+```bash
+genezio deploy
+```
+
+Genezio will provision the necessary resources to ensure that your server remains running continuously.
+
+After deploying, you can send requests to your server using the generated endpoint URL available in the Genezio dashboard or in the CLI output.
+
+:::tip info
+To send requests to your persistent server, do not forget to prepend `compute-` to the endpoint URL.
+The format should be `https://compute-<server-uuid>.<region>.cloud.genez.io`.
+:::
+
+Note: Sending requests to the URL `https://<server-uuid>.<region>.cloud.genez.io` will trigger a serverless call instead of a persistent server call.
+
+## Enterprise Support
+
+Persistent servers are available as an Enterprise-only feature.
+If you are interested in deploying a persistent server on Genezio, please [contact us](mailto:[email protected]) for more information.

+For further details on server types and configurations, refer to the [Genezio Configuration File](/docs/project-structure/genezio-configuration-file.md).

+  The type of the function. This can be: `aws`, `httpServer`, or `persistent`. If this field is not specified, the default value is `aws`.
 
   - `aws` indicates that the function will be deployed as an AWS Lambda handler. This means that the function is either a Lambda event handler or it uses [`serverless-http`](https://www.npmjs.com/package/serverless-http) to convert an Express app to a Lambda event handler.
   - `httpServer` indicates that the function will be deployed as a standalone HTTP server, such as those built with frameworks like `express`, `fastify`, `flask`, `django`, etc.
+  - `persistent` indicates that the function will be deployed as a long-running server that will not be scaled down to 0. This is an Enterprise-only feature, please [contact us](mailto:[email protected]) for more information.
 
   Note 1: The recommended way to deploy your app is to use the `httpServer` type unless you are explicitly migrating from an existing AWS Lambda function or using `serverless-http`.
   Note 2: Websocket are supported only for `httpServer` functions.
