# Validio Services

> A summary of Validio backend and frontend services.

The Validio platform is made up of two applications:

* **Validation Engine**: The backend application and consists of the services: `Diver`, `Ingress`, and `Pipelines`.
* **Surface**: The backend server that communicates between the browser client and the Validation Engine.

The following table lists all the Validio services. We recommend that you use this list as a reference when you allocate resources to services running in your system.

| Validio Service | Description |
| :- | :- |
| `Diver` | Orchestrator and running background tasks for the Validio application. |
| `Ingress` | Connects to configured sources to read statistics, data, and source metadata. |
| `Pipelines` | Handles processing of any read data and performs calculations and anomaly detection on data statistics. |
| `Surface` | Responsible for communication between the frontend application in your browser and the Validation Engine. |
| `Postgres` | Stores all platform data and configuration settings. |
| `Redis` | Used as a transport layer between different services. |

You can view the status of each service in the **Workspace > Settings** page. See [Platform Configuration](https://docs.validio.io/v11.1/docs/access-and-settings/settings.md).
