DESKTOP VIRTUALIZATION

DESKTOP VIRTUALIZATION

1. DEFINITION: Desktop virtualization is a method of simulating a user workstation so it can be accessed from a remotely connected device. By abstracting the user desktop in this way, organizations can allow users to work from virtually anywhere with a network connecting, using any desktop laptop, tablet, or smartphone to access enterprise resources without regard to the device or operating system employed by the remote user.

2. WORKING: Remote desktop virtualization is typically based on a client/server model, where the organization’s chosen operating system and applications run on a server located either in the cloud or in a data center. In this model all interactions with users occur on a local device of the user’s choosing, reminiscent of the so-called ‘dumb’ terminals popular on mainframes and early Unix systems.

3. BENEFITS:

   • Resource Utilization: Since IT resources for desktop virtualization are concentrated in a data center, resources are pooled for efficiency.
   • Remote Workforce Enablement: Since each virtual desktop resides in central servers, new user desktops can be provisioned in minutes and become instantly available for new users to access.
   • Security: IT professionals rate security as their biggest challenge year after year. By removing OS and application concerns from user devices, desktop virtualization enables centralized security control, with hardware security needs limited to virtualization servers, and an emphasis on identity and access management with role-based permissions that limit users only to those applications and data they are authorized to access.

4. TYPES:

   • VDI simulates the familiar desktop computing model as virtual desktop sessions that run on VMs either in on-premises data center or in the cloud.
   • RDS is often used where a limited number of applications need be virtualized, rather than a full Windows, Mac, or Linux desktop.
   • DaaS shifts the burden of providing desktop virtualization to service providers, which greatly alleviates the IT burden in providing virtual desktops. Organizations that wish to move IT expenses from capital expense to operational expenses will appreciate the predictable monthly costs that DaaS providers base their business model on.
