The virtual desktop brings applications and data together in a cloud.

This environment is non-adherent to the client, ie the user must be able to recover this environment from any terminal (client, laptop, computer, etc …).

What are the benefits of virtual office?

They are numerous!

Protection against loss of data
One of the main advantages of having a virtual office like Wyoming Virtual Offices is the trivialization of the physical medium (computer) which becomes a simple consumable. It protects against theft or hardware failures since all data is in the Cloud.

Accessibility of data and applications

The virtual desktop may be required to access legacy applications that are in the cloud but have not been designed to be accessible in web mode. An interesting tool when we know that the average lifetime of an application within the company is about 15 years.

Simplifying day-to-day management
By centralizing data and applications, backups are much easier to manage on a daily basis and no longer depend on the user station. Security management is also centralized.

In addition, cloud availability and SLA commitments ensure a workstation availability rate.

Mobility and BYOD
The BYOD or Bring Your Own Device is made easier with the introduction of the virtual desktop. The company provides a complete working environment, capable of operating on any terminal. The user can then distinguish between his professional environments (in the virtual office) and his personal environment.

The arrival of a new collaborator is greatly simplified by simply assigning him a computer without installation and giving him access to his virtual office.

The virtual desktop: TS vs. VDI

There are two ways to create virtual desktops: the shared desktop and the VDI

The shared office
Historically known as Remote Desktop, it is based on Terminal Services (TSE) environments. This system involves sharing an operating system with multiple users. The operating system is typically centered on Windows Server environments. The user accesses a virtual session and can have an environment as if it were his own computer.

Advantages

Low bandwidth consumption per user, which is on average around 125 Kbps. For an agency that has a large number of users, this reduces operator costs.
Securing environments, since the system administrator is the only one able to install applications, it has a better control.
An attractive cost unlike VDI because it allows pooling virtual machines for users and does not require important operator links.
Limits

The lack of autonomy for the user in the installation of his own applications.
Applications must run in “client-server” mode.
Graphic performance remains very limited, especially for advanced uses such as video viewing, skype-type conferencing, or the use of drawing software.
Shared desktop environments are ideal for desktop use and access legacy applications in the cloud.

VDI: Virtual Desktop Infrastructure
Unlike the shared office, the VDI has its own IT resources. Each user then accesses a virtual machine that has its own operating systems.

On the Microsoft side, there are several ways to do VDI using either:

– a desktop operating system (Windows 10, XP etc …): The company must acquire VDA licenses in perpetual mode and ensure the use of an infrastructure dedicated to the company.

– a server type operating system (Windows Server 2008, 2012, 2016, etc …): The company can benefit from pay-per-use and use public cloud environments.

Advantages

The autonomy of the user and the possibility of installing his applications in the virtual office.
Improved user experience with superior graphics performance compared to shared desktop.
It can support single-user applications
The availability of the virtual office.

Limitations

The cost can be high depending on the choice of the company in terms of Microsoft license or infrastructure.
The bandwidth consumption is higher than a shared desktop and can average about 2 Mbps per user.
Additional management tools may be required to manage these distinct environments.
VDI environments can meet the needs of small and medium-sized businesses that want to have a few jobs or to meet very specific needs in large companies.

DaaS, the Desktop as a Service

The Desktop as a Service provides access to a virtual desktop with pay-per-use. That is, the company pays according to the number of virtual desktops. The DaaS is mainly based on VDI technologies.

The virtual office is a smart solution for companies who want to outsource and secure their entire information system and do not have all the applications in SaaS mode. In particular, the company must take into account its budget and the uses of its users to define the most appropriate solution.
