.. title:: System Requirements

Kasm Server Requirements
================================

Kasm Server can be installed in a :doc:`single server <single_server_install>` or :doc:`multi server <multi_server_install>` setup.

Operating System
----------------
Kasm Services and end user Kasms are :term:`Docker` containers. Access to the Docker registry is required for
installation.


Installation is supported on the following operating systems:

    +----------------------+
    | Ubuntu 16.04 / 18.04 |
    +----------------------+
    | Debian 9             |
    +----------------------+
    | CentOS 7             |
    +----------------------+

Resource Requirements
---------------------

.. table:: **Minimum Requirements**
    :widths: 100,100

    +-------------+------------+
    | **CPU**     | 1 core     |
    +-------------+------------+
    | **Memory**  |        2GB |
    +-------------+------------+
    | **Storage** | 30GB (SSD) |
    +-------------+------------+


.. note::
    Although the requirements for the Kasm services a quite modest, provisioning each end-user :term:`Kasms <Kasm>`
    requires additional compute resources as specified in the :term:`Image<Image>` configuration. The default Kasm
    Images are :doc:`configured <../guide/custom_images>` to require 768MB of memory and 1 core. Kasms will not be
    provisioned if the minimum resources requirements on the :term:`Agent` are not met.





End User Requirements
=====================

End-users access the Kasm Server via the web ui. Most modern browsers are supported.
