## Server-side Requirements for Evaluation or Development

The below requirements outline the minimum needed requirements. If you need help sizing your server, please contact us at <https://www.vardot.com/contact-us> for consultation.

* **Disk space**: Minimum 300MB for codebase, 5GB for files, and 1GB for the database *(Will greatly depend on your application data and usage)*.
* **Memory**: Minimum of 2GB (for 1 host). Minimum PHP memory of 196MB *(might need to increase this as your Varbase site's functionalities increase).*
* **CPU**: Minimum of 2 CPUs is recommended (for 1 host).

To deploy and run Varbase your web server must meet certain minimum requirements. We recommend sizing your application and considering your database size, files data, and expected traffic.

Your servers' requirements will greatly be impacted by the usage of your application. For example, if you have more logged-in users that are anonymous users, you will need to consider higher requirements to serve non-cached requests.
