Product description for Desktop as a Service (DaaS)

Last update: May 30 2026

Desktop as a Service (DaaS) is a service that allows you to work with a remote computer using a virtual desktop (Omnissa Horizon®-based VDI) in Selectel's cloud powered by VMware.

You can purchase any number of desktops.

Use cases

• quick connection of users to secure company servers from their own devices or to their workstations when working remotely;
• working with graphic applications that require high computing power and cannot run on user devices (3D modeling, CAD, high-quality graphics, video editing, etc.);
• increased data storage security. Since data is not stored on the device, it can be disconnected from the remote desktop if the device is lost.

How it works

Selectel hosts infrastructure, network resources, and storage in a cloud powered by VMware and delivers the virtual desktop to the user's device. You access desktop data and applications via a browser in Omnissa Horizon HTML Access or through the Omnissa Horizon Client.

Virtual machine load balancing is automatic.

Configurations

DaaS is provided in fixed configurations with or without a GPU. Remote desktops are available based on several operating systems.

	Configuration 1	Configuration 2	Configuration 3	Configuration 4	Configuration 5	Configuration 6
vCPU count	2	4	8	4	4	8
RAM	4 GB	8 GB	16 GB	16 GB	32 GB	32 GB
SSD	200 GB	200 GB	200 GB	200 GB	200 GB	200 GB
GPU	✗	✗	✗	2 GB	2 GB	4 GB

Technical description

DaaS uses:

• NVIDIA® A16 GPU based on the NVIDIA Ampere® architecture;
• AMD EPYC™ 7343 processor with a 3.2 GHz base clock frequency;
• disk subsystem: vSSD (5 000 IOPS);
• NVIDIA® license (included).

If you want to customize desktops for your needs, use desktop rental in a private cloud powered by VMware (from 50 desktops).

Available OS

• Windows Server 2022 (English);
• Windows 10 LTSC (Russian);
• Windows 11 23H2 (Russian);
• Ubuntu 22.04.

System requirements

User device requirements

• for access via Omnissa Horizon HTML Access, the user browser must meet system requirements; for details, see System Requirements for HTML Access in the Omnissa documentation;

• for access via Omnissa Horizon Client, the user device and OS must meet system requirements; for details, see the tutorials in the Omnissa documentation:

  • Hardware and Software Requirements for Windows Client Systems;
  • System Requirements for Linux Client Systems;
  • System Requirements for Mac Clients.

NVIDIA driver requirements in VDI

For vGPU in VDI to work properly, the driver version on the virtual machine must match the version installed on the virtualization host. Virtualization hosts use driver releases from the LTSB branch (Long-Term Support Branch).

You can check driver versions in the NVIDIA documentation.

Omnissa Horizon Client version requirements

If you use Omnissa Horizon Client, its version must be the same as or newer than the Omnissa Horizon Connection Server and Omnissa Horizon Agent version.

We recommend using the latest version of Omnissa Horizon Client, which can be downloaded from the Omnissa Customer Connect website, the App Store, and Google Play.

Areas of responsibility

Selectel provides:

• maintenance and high availability of the desktop;
• backup of the service infrastructure, data updates, and storage;
• load balancer configuration;
• monitoring;
• connectivity between Selectel services (Selectel Global Router);
• restoration of functionality in case of failure.

Selectel is not responsible for the operation of software running on a remote device or for the stability of the user's internet connection.
