Computers have evolved over the past 25 years into crucial change agents for businesses, industries, and classrooms worldwide. Desktop virtualization is a buzzword in computing that has emerged over the past ten years. It is backed as a solution to the ever-increasing problems businesses confront, including cost control, regulatory compliance, manageability, security, and business continuity.
What is desktop virtualization?
Desktop virtualization is a technique that permits creating and storing several desktops for users on one host, which is housed in the data center or the cloud. This accomplishes through a hypervisor that sits over the host server hardware, allowing virtual desktops to benefit from the computing power of the hardware of the server that runs them. The hypervisor makes VMs that emulate the desktop environments of the user. These can contain different operating platforms, applications, customized settings, and user data. Users can remotely access and manage desktops from any device.
Desktop virtualization allows users to manage their desktops individually in a single central server. Users may connect to the main server via either a LAN or WAN connection or via the Internet.
What is the process behind Desktop Virtualization work?
Remote Desktop Virtualization is generally built on a model of client/server, which means that the chosen operating system and software runs on a server either in the cloud or the data center. In this scenario, all interactions with users happen using a device local to the user’s preference and are reminiscent of the so-called dumb terminals that were popular on mainframes and early Unix systems.
What are the different types of Desktop Virtualization?
Desktop virtualization, seen as a substitute for conventional distributed software distribution, consists of the Hosted Desktop and Client Virtualization deployment types.
Hosted Desktop Virtualization
In this kind of desktop virtualization, virtual machines are really hosted by a computer server located in a data centre, which allows users to connect to the server using connection brokers or industry-standard protocols like Remote Desktop Protocol (RDP).
There are three primary ways that hosted desktop virtualization carry out:
Virtual Desktop Infrastructure (VDI) simulates the traditional desktop computing model using virtual desktop sessions on VMs that are either on-premises in a data center or cloud. The companies that use this approach manage their desktop virtualization server similarly to any other application server running on-premises. Since all computing for end users is transferred from the users back to the center of data, initially setting up servers that run VDI sessions is significant but is offset by the absence of the need to keep updating devices for end users.
Remote Desktop Services (RDS) commonly use when only a few applications require virtualization instead of a complete Windows, Mac, or Linux desktop. In this scenario, applications are streamed locally to the OS’s device. Because only applications are virtualized, RDS systems can offer a higher density of users per VM.
Desktop as a Service (DaaS) shifts the responsibility of offering desktop virtualization to service providers. This significantly reduces the IT burden of offering virtual desktops. Companies that want to turn IT expenses from capital costs to operational costs will benefit from the predictable monthly expenditures that DaaS service providers have their business models based on.
A hypervisor must install on a client device in this desktop virtualization approach to run multiple operating systems. This eliminates the need for users to maintain their specialized hardware and software.
Client virtualization deployment mostly comes in two main varieties:
1. Presentation virtualization
This makes a web-based portal available for users to communicate with desktops and applications.
2. Application virtualization
Applications can run on several platforms thanks to this client virtualization strategy. They are running Windows applications on a Linux computer, for instance.
Advantages of using virtual desktop
One of the many advantages of desktop virtualization is that maintenance costs reduce. With the growth of cloud computing, businesses can now do away with the conventional machine-based IT strategy and build virtual desktops that don’t need individual upkeep. Discover the main advantages of virtualizing desktop by reading on.
Secure Mobile Application Access
Many SMBs allow workers to work remotely or after hours using their own devices, but provisioning them may be time-consuming and expensive. Furthermore, enabling workers to provide their own devices exposes the business to security threats. However, virtualized desktops enable hardware-based GPU sharing through a secure connection from any device, even on high-latency, low-bandwidth networks like hotel room WiFi, allowing employees to access even high-performance applications.
Fewer types of desktops can be provided to users by businesses using desktop virtualization, eliminating the need to set up individual computers for each worker. In addition, virtual desktop infrastructure (VDI) makes it simpler for the business to onboard new hires with only a few mouse clicks because it can deploy so fast. The ideal virtualization system will enable an administrator to customize and control desktops from a single interface without going down to individual desktops.
Additionally, desktop maintenance make simpler with virtualized desktops. The desktop can reset once the employee logs off from the computer at the end of the day, erasing any downloaded programs or changes they might have made. This not only keeps software and customizations from making the computer sluggish, but it also offers a simple way to troubleshoot. For example, if the system freezes, the worker only needs to reboot to get their desktop back.
- Desktop defense
Employees downloading software or other potentially harmful goods (like PowerPoint presentations with adorable kittens — and viruses) is a concern that most SMBs encounter. With desktop virtualization, the administrator can configure permissions to stop these Trojan-horse-carrying documents from staying on the system. This offers, quite simply, peace of mind and ease of maintenance costs.
Reduced costs for the firm are the common thread connecting these advantages. Cost reductions on apps alone result from the decreased software license requirements. Companies also save money in the IT department since managing PCs and solving user issues requires fewer staff members. Finally, SMBs also save cash on significant support concerns like malware removal.
HPE GreenLake for Virtual Desktop
When conducting business away from the office, workers may use any tablet, smartphone, or PC–trusted or not–as is typical in today’s bring-your-own-device, work-from-home environment. With the virtual desktop infrastructure (VDI), it is possible for employees to not store sensitive company information on personal devices, which could steal easily, lost, or altered. HPE GreenLake for VDI is a secure VDI on-premises, custom-made to users’ requirements. It can help you reduce upfront costs, reduce the time-to-value, and expand quickly to match resources to the demand.
It doesn’t matter if you’re trying out virtual desktop infrastructures for the first time or if your existing VDI environment is challenging many applications and user requirements. The HPE GreenLake platform can deliver the security performance, efficiency, and compliance advantages that come with an on-premise VDI solution while retaining the simplicity and flexibility of the cloud.
HPE is a platform that supports, operates, and controls the system to provide high performance and reliability while ensuring complete control over crucial desktop and application environments. The endpoint device can be a regular PC, a thin device designed for clients, or even a mobile device. HPE GreenLake provides the standard desktop experience specifically designed to meet the demands of the majority of users. You can select the mix of both users and users based on your requirements and have the ability to change and expand the mix to suit your specific business needs.
