What is Desktop Virtualization?
Desktop virtualization is a way to simulate a user’s workstation virtualization so It can then be accessed remotely from any connected device. This abstracts the user desktop. Organizations can offer remote access to their resources, allowing users to work anywhere there is a network connection. This includes any smartphone, tablet, or desktop computer.
Remote desktop virtualization is also an important component of digital workspaces. Virtual desktop workloads are run on a desktop virtualization server which usually executes on a virtual machine (VMs), either in an on-premises data center or in the open cloud. There are many benefits to virtualizing desktops. These benefits can vary depending on the deployment model.
The user device is essentially a display, keyboard, and mouse. This reduces the risk for the company if the device is lost or stolen. All data and programs are stored on the desktop virtualization server.
What are the Benefits of Desktop Virtualization?
- Resource Utilization: Because IT resources for desktop virtualization have been concentrated in a single data center, they can be pooled to maximize efficiency. Virtualized desktop applications can be accessed from any device, including smartphones, tablets, desktops, laptops, and tablets. Because they are only used for input/output, IT organizations can deploy smaller and more affordable client devices.
- Remote Workforce Empowerment: Because each virtual desktop is stored in central servers, new desktops can be created in minutes and made immediately available to new users. IT support staff can concentrate on the virtualization servers and not the end-user device that is being used to access the virtual desk. Users can access their business applications from anywhere with internet connectivity, as all applications are delivered to them over a network. Users can return the resources they used to create their virtual desktop to the centrally-managed infrastructure if they leave the company.
- Security: IT professionals rank security as their greatest challenge every year. Desktop virtualization removes OS and application issues from users’ devices. It allows for central security control with hardware security limited to virtualization servers. There is an emphasis on identity management and access management, which limits access to only those applications and data that the user has permission to access. There is no need for an employee to delete applications or data from their devices if they leave the company. Any data stored on the device is temporary by design and is not retained after a session ends.
How does Desktop Virtualization Function?
Remote desktop virtualization uses a client/server model. The organization’s preferred operating system and applications are run on a server either in the cloud or in a Data Center. In this model, All interactions with users take place on the local device chosen by the user, recalling the so-called dumb terminals that were popular on Unix and mainframes.
Types of Desktop Virtualization?
Three of the most popular types of desktop virtualization include Virtual Desktop Infrastructure (VDI), Remote Desktop Services (RDS), and Desktop-as-a-Service.
VDI is a virtualization of the desktop computing model. It consists of virtual desktop sessions that are run on VMs in either an on-premises or cloud data center. This model allows organizations to manage the desktop virtualization server in the same way as any other server on-premises. All end-user computing is transferred from the users back to the data center. This can make the initial deployment of VDI servers a significant investment. However, it is also less expensive than having to refresh the end-user devices constantly.
RDS is used when only a few desktop virtualization software must be virtualized rather than a full Windows, Mac, or Linux desktop. This model allows applications to be streamed to a local device that runs its own OS. Only software can be virtualized on desktops, so RDS systems offer higher user density per VM.
DaaS enables service providers to shift the responsibility of desktop virtualization to them greatly reduce IT costs by providing virtual desktops. Organizations who wish to shift IT expenses from capital expenditure to operational expenses will benefit from the predictable monthly costs that are the basis of DaaS providers’ business models.
Desktop Virtualization vs Server Virtualization
Server virtualization is where a server OS and its apps are abstracted from the underlying hardware using a hypervisor to create a VM. Multiple virtual machines can be run on a single server. Each VM has its own OS and applications. All the required dependencies for execution as if it was running on bare metal.
Desktop virtualization abstracts client applications (OS and apps) from a physical thin client that connects to remote applications and data, usually via the internet. This abstraction allows users to access their virtual desktop from any device. Depending on how many concurrent users are active during peak, desktop virtualization can significantly increase the bandwidth requirements of an organization.
Desktop Virtualization vs App Virtualization
Application Virtualization isolates executable programs from the underlying devices, while desktop virtualization abstracts all desktop components – applications and OS – making them accessible to virtually every client device. Application virtualization makes it easier to install each application.
Each program is first installed on a server, then virtualized to any end-user device. Client devices receive a pre-configured executable that is packaged and ready to go. This makes it much easier to deploy. One instance only needs to be updated. Retired applications can be deleted from the application server.
This will remove it from all users. Virtualized applications are stored in their own containers so they can’t interact with other applications or cause them to fail. Virtualized applications can also be used on any device, regardless of their underlying OS.
Application virtualization isn’t right for all applications. Application virtualization is not suitable for all applications. Graphics-intensive and compute-intensive applications may experience slowdowns that cause visible lag in rendering. A broadband connection is essential to deliver a user experience similar to local device apps.
