Desktop Virtualization Deployment Models
Virtual Desktop Infrastructure (VDI)
VDI or Virtual Desktop Infrastructure deploys operating systems as virtual machines in data centers and then sends that desktop image over the network directly to users devices where it can be interacted with as though locally.
VDI allows each user to have access to their own dedicated VM running its own OS, while hypervisor software manages resource allocation across multiple VMs while simulating operating system resources, including CPUs, drivers, and memory usage.
VDI provides users with Windows 10 on any of their own devices - an essential capability. However, due to VDI only supporting one Windows 10 user at once, a virtual machine must be created per Windows 10 user in the VDI server.
Remote Desktop Services (RDS)
Remote Desktop Services (RDS), also referred to as the Remote Desktop Session Host or RDSH (Remote Desktop Session Host), enables users to remotely access Windows desktops and applications over Microsofts Server Operating System using Microsoft Remote Desktop Protocol for desktop images delivery, previously referred to as Microsoft Terminal Server this product remains relatively unchanged since its initial introduction.
RDS provides end users with virtual desktop environments similar to VDI; however, RDS may prove more cost-effective as Windows Server supports as many concurrent users simultaneously as VDI can.
Furthermore, applications certified and tested to work on Windows 10 might not necessarily function the same on a server OS environment.
Desktop-as-a-Service (DaaS)
Desktop-as-a-Service (DaaS) DaaS is an emerging cloud management service model where virtual machines (VMs) can be hosted by third-party providers on an external backend and provided overtime via subscription models.
DaaS allows easy scaling, greater flexibility than on-premise solutions, and can deploy quicker.
DaaS is one form of desktop virtualization in cloud management that shares many advantages associated with cloud computing, including accommodating fluctuating workloads, flexible storage requirements, and usage-based pricing plans, as well as accessing your data from virtually any connected device over the internet.
Unfortunately, DaaS does not always permit customization options, and features arent always bespoke to individual clients requirements.
Choosing a Model
VDI has become increasingly popular as it provides an intuitive virtualized model of traditional desktop computing.
Implementation requires managing all components involved - the hypervisor, operating system, applications, and associated software can make managing VDI complex; experts may require considerable expertise or experience with VDI to effectively use its benefits; initial costs could also be considered for infrastructure components needed to run VDI effectively.
RDS/RDSH can be the ideal solution if all thats required to access certain applications rather than an entire Windows desktop is accessing some applications only.
RDS allows a higher end-user count per server than VDI; additionally, its cheaper and scalable systems make deployment simpler for administrators and managers. In order to properly administer and manage RDS/RDSH systems, your staff must possess all of the appropriate skills.
DaaS has become increasingly popular as more IT teams adapt to using shared desktops for shared desktop virtualization services (VDI).
VDI requires little expertise within companies for management purposes and offers more cost-effective cost structures since scalable infrastructure means reduced capital and operating expenditures.

Desktop Virtualization: Benefits
There can be various advantages associated with virtualizing desktops depending on which model is selected.
Virtual desktop technology brings many advantages depending on the deployment model chosen; six specific benefits stand out as particularly notable.
Simplified Administration
Desktop virtualization enables IT administrators to remotely administer servers, speeding deployment and simplifying maintenance while saving both time and IT resources for an organization.
Secure And Mobile Access To Apps
Secure mobile access utilizing virtualized desktops provides organizations with an affordable way to offer high-performance apps to remote workers through secure connections on any device, offering them high-productivity applications without interruption from anywhere on their desktop PCs or phones.
Enhanced Employee Productivity
Employee productivity can be improved via virtual desktop access from any location at any time and from any device - ideal for telecommuters as employees have easy access to apps and functionality remotely.
Reduced Downtimes And Accelerated Deployments
Reduce Downtimes and Accelerate Deployments Virtual desktops allow users to easily switch VMs in case of failure, thus maintaining productivity without incurring downtimes or time loss.
Furthermore, IT admins can rapidly deploy new hardware within an infrastructure framework in order to quickly bring on board new employees who require getting up-and-running with your workflows.
Reduce IT Costs
Desktop virtualization technology enables companies to shift their IT spending away from capital expenses and towards operating expenses, saving companies both capital and operating expenditure costs by moving computationally-intensive apps onto virtual machines hosted in data centers - prolonging the shelf life of older PCs or lesser machines while decreasing software licensing fees through installing apps only on one central server rather than multiple workstations.
Enhanced User Experience
Enhance the user experience Desktop virtualization offers a rich user experience without the need to sacrifice hardware running apps.
Users have access to USB ports and printing services, for instance.
IT departments can streamline employee computing requirements with desktop virtualization more easily by creating one virtual machine for all employees with similar roles and functions, rather than maintaining individual computers that need updates/patches every time software needs changing - saving both time and resources!
Savings on Costs Virtual desktops enable your organization to allocate more of its IT budget towards operational expenditures, freeing up money for operations.
Desktop virtualization extends the lifecycle of less-powerful PCs by running compute-intensive apps via virtual machines in a data center server environment. Traditional virtual desktop installation may be costly as it requires server hardware and hypervisor software licenses, whereas cloud DaaS models allow customers to pay only for what services are used by paying per service consumed instead.
Productivity can be enhanced via desktop virtualization. Employees now have easier access to enterprise computing resources from any location with Internet connectivity - with any device providing Internet service supporting all kinds of access points at any given moment in time and space.
Virtual desktops support many device types. Virtual desktops enable remote desktop accessibility from desktop and laptop computers, thin client, and zero client devices such as tablets or some phones - providing a workstation-like experience and access anywhere regardless of operating systems native to devices in use by end users.
Strengthened security. Desktop virtualization helps increase enterprise ITs control by isolating desktop images from any specific hardware that they run on, making VM management much simpler and more secure.
Scalability and flexibility. As required, creating new virtual machines (VMs) quickly to host applications is simple and swift; similarly, removing them once no longer necessary is straightforward as well.
Enhance end-user experiences. Desktop virtualization enables your users to enjoy all the newest features without compromising functionality that has come to be relied upon over time.
Desktop Virtualization Software
Your virtualization method will determine what software will be necessary to deliver virtual desktops.
Virtual desktop infrastructure (VDI) enables desktop operating systems (usually Microsoft Windows) to be managed and deployed within the data center.
A hypervisor runs on each server to give every end-user access to a VM over the network; software known as a connection broker authenticates users, connects them to virtual computers, tracks activity, reassign VMs when connections terminate, and reassign when necessary. Hypervisors may be purchased either individually or as bundles.
Microsoft Windows Server includes utilities to implement Remote Desktop Services/Hosted Desktop Services (RDS/RDSH).
DaaS solutions (Desktop as a Service, DaaS for short) take care of installing, configuring, and managing software - such as OS, applications, user preferences, or files.
They do all this with zero hassle to you as the client.
Desktop Virtualization Types
There are two primary deployment models for virtual desktop environments - Hosted Desktop Virtualization and Client Virtualization.
-
Hosted Desktop Virtualization
Hosted Desktop Virtualization involves hosting virtual machines on servers located within data centers; users access these servers using standard protocols like Remote Desktop Protocol or connection brokers to gain access.
There are three primary variations of this model.
-
Virtual Desktop Infrastructure
Virtual Desktop Infrastructure is built around virtual machine (VM) concepts that use OSes such as VMware to run desktop images within data center servers.
VDI utilizes a hypervisor in order to divide each server up into separate desktop images that users can remotely access through endpoint devices; each user in VDI receives their own OS-equipped VM within a virtualized environment.
-
Remote Desktop Services
RDS (formerly Terminal Services ) enables access to shared Windows desktops, applications, and host resources located on Microsofts Windows Server operating system remotely via RDP (formerly Terminal Services).
Users gain remote desktop access by sharing hardware (in this instance, Windows Server OS), hardware operating system software applications hosting resources, and resources hosting resources between remote desktops shared using RDP.
-
Desktop-as-a-Service (DaaS)
DaaS offers similar functionality as VDI by enabling users to access desktops and applications from any device. However, rather than purchasing, managing, and deploying all hardware components separately, as with VDI, DaaS allows companies to outsource this function altogether.
What Are My Choices Between VDI and RDS?
Your decision regarding which service (VDI or RDS) to select will ultimately depend upon user experience, business requirements, cost considerations, geographical considerations, and agility considerations.
Businesses Capabilities
Before embarking upon VDI or RDS implementation, an organization needs to ascertain that it possesses both the expertise and resources necessary for its deployment.
If this is the case for them, consuming desktop virtualization "as-a-service" instead may prove more efficient; you could leverage cloud resources or employ DaaS if there are not enough personnel dedicated to VDI/RDS management.
Cost Analysis
Pricing should always be your top consideration, no matter if its VDI or RDS implementation. CAPEX costs play an essential part in VDI deployment - these cover infrastructure setup, scaling costs, and ongoing maintenance fees - while DaaS allows RDS users to execute desktop tasks remotely in the cloud desktops.
DaaS is costed on an operational expenditure basis and more flexible than VDI or RDS. its use should only be considered suitable if an organization can anticipate IT use patterns with adequate resources available to it.
Control of Infrastructure
IT administrators have complete authority when it comes to VDI or RDS deployment for updating infrastructure and securing services, making this the optimal solution for organizations aiming at controlling their infrastructure - this applies especially to industries with stringent regulations.
DaaS is an alternative that outsources infrastructure management from organizations to cloud providers, offering faster updates and wider possibilities of use cases, however, in industries with stringent regulations, it might not be the ideal option.
Geography
In order to accurately compare VDI with RDS and DaaS, an organization should first understand where its data resides and who its users are.
DaaS offers multiple users in multiple locations access to its service at once, while it also makes for an ideal option if all or some of your data already resides on cloud storage solutions.
Your RDS or VDI deployment must be situated close to its supported site for best results since proximity will mean lower network latencies compared with deployments located miles from their users.
Otherwise, RDS/VDI deployments could adversely impact user experiences when their data centers are located far from them.
Agility and Elasticity
Agile and elastic, DaaS may be your ideal virtual desktop solution if your goal is easy installation and management of desktop virtualization solutions for seasonal workers or contract employees.
DaaS offers more advantages over RDS or VDI than these other options do when providing desktop virtualization as part of an employee benefits program or contract management initiative.
Below is a table comparing VDI and RDS according to key categories such as business capability, cost, geographic location, and agility infrastructure control.

What is Client Virtualization?
Client Virtualization, also referred to as Client VPS (or Client Virtualization), involves installing a hypervisor onto an end-user device in order to run multiple OSs at the same time without using the hardware and software necessary for running each operating system.
Client virtualization deployment methods typically fall into one of two categories.
Presentation virtualization provides users with easy access to virtual desktops or applications published online via presentation virtualization portals, providing organizations with an efficient means of dispersing apps and desktops via shared servers.
Application Virtualization
App virtualization enables applications to run across platforms; you could, for instance, run Windows applications on Linux without installation issues.
Application virtualization also creates portable software, which makes OS migration much simpler as portable apps can easily be transferred between computers without being uninstalled every time.
Desktop Virtualization Vs Server Virtualization
Server virtualization uses a hypervisor to separate operating systems (OS), applications, and hardware on one physical machine from another; multiple VMs running concurrently on it could each feature their own OS and applications.
Desktop virtualization involves distancing client software (OS, applications) from its physical embodiment and connecting it remotely through the internet - typically providing remote users access from anywhere with virtual desktops that provide connectivity from anywhere with data and programs accessed remotely - in this way enabling any user to securely log-on anywhere through any means at any time; bandwidth requirements of an organization could potentially increase drastically depending upon how many people use their systems simultaneously at peak times.
Desktop Virtualization Vs Application Virtualization
Application virtualization involves isolating software from its physical environment, while desktop virtualization encases it.
Virtualization makes the installation of app platforms simpler than ever. Each app first installs on one computer before being virtualized to be run across various end-user devices - each client device receiving its own preconfigured, packed executable - making deployment much less cumbersome and painful than before.
Virtualized applications are easier to manage since they reside as one instance on an application server, and updates are applied across only that instance; when retiring a program, both its instances on both ends must be deleted simultaneously from both instances - all virtualized programs residing inside their "containers." They dont interact or interfere with one another like they might if installed directly onto user computers.
Virtualization may not always be suitable for every application; some graphics- and compute-intensive apps could slow down or experience delays while rendering.
A strong broadband connection will be essential in providing comparable user experiences.
Implementing Desktop Virtualization
Desktop virtualization can be a complicated and time-consuming task for organizations of any kind, yet some vendors offer convenient virtual desktop options that could make this journey simpler than anticipated.
If your organization doesnt select an ideal virtual desktop provider, however, implementing virtualization could become expensive and complicated quickly.

Trends In Desktop Virtualization
Data virtualization refers to an approach for managing information that allows applications to manipulate and retrieve it without needing to know technical details about its format or physical location.
Virtualization experts believe we are now living in an age of virtualization; be it server virtualizations, desktop virtualizations, network virtualizations, storage virtualizations, and containerizations; but data virtualization promises to become the next big wave. Let us look at ten popular data virtualization technologies of 2023 here.
Cloud Native Protocol
Cloud native architecture holds immense promise; some companies have announced cloud-first initiatives or cloud-only projects, making cloud development one of the top 10 trends for 2023 in the IT industry.
At the same time, developers face growing challenges as cloud apps become popular compared to the Windows ecosystem in the 1990s; Windows quickly became ubiquitous due to developer involvement; this trend will likely play out similarly when most developers begin creating apps in 2023, particularly ones dedicated to virtualization - one of 2023 top IT trends!
Virtualization for Data
Data virtualization has the power to change paradigms by shifting how IT architecture operates: traditionally, data has moved between applications or databases and processing and analysis applications or databases at an extremely fast rate, but our traditional model cannot keep pace.
With real-time processing demands such as reallocation of data between applications rather than vice-versa being required now more than ever, it was necessary for changes to take place that shifted focus away from data to applications rather than vice versa.
Productive Data Insights
Strongly supports self-service insights as a growing trend, not surprisingly since consumer insight teams are busier than ever and customer centricity becomes ever more crucial in business today.
He credits data management market growth with fueling this rise of self-service insights. Philogene further asserts this statement with being no coincidence when customer centricity has become ever more crucial over time.
Data Democratization
Data Democratization Accessing analytics data has never been simpler for more people with self-service. The rise of insight democratization stems from technology making information more available across stakeholders; while insight democratization was already present prior to 2010, its prominence accelerated significantly, with IT Industry data virtualization trends becoming the number one trend over time.
Organizational Shift
Organizational Shift Data virtualization has led organizations to assess how they display data and insights throughout their enterprise.
Sales managers and heads of the line of businesses have had greater access to more data in recent years through dashboards with limited self-service analytics capabilities; next step: unleash peoples inherent knowledge to use analytics for personal gain - typically, sales managers have proven superior at finding unique nuggets of insight from data that had never previously been made accessible via self-service analytics tools.
Shifting Algorithms to Databases
Virtualization has reached its pinnacle when data and applications move from on-premises servers into the cloud, creating the ultimate expression of virtualization: cloud migration.
Data virtualization continues to expand while cloud storage and computing become more cost-effective and accessible on the market; more organizations are choosing this path of virtualization over physical storage for both their stored information and processing,
Rise in Data Centers
Data Centers Are on the Rise Users want their data centers to consolidate both logically and physically with minimal restrictions in mind or have the flexibility of stacking containers and database instances without operating system restrictions limiting this ability.
They want reduced OS sprawl, hardware restrictions, and greater high availability and disaster recovery capabilities - they even wish for Docker-based environments integrated with high availability frameworks that support stateful containers failover between hosts without losing persistent data - to meet rising user demand for liberated data centers - one of 2023s key trends!
Cloud Data Warehouses
Cloud data warehouses play an increasingly prominent role in how businesses access and organize their information.
These cloud native technologies can hide a range of information behind tables and views. Max Seiden of Sigma Computing noted that while each vendor may offer distinct features now, eventually, all vendors will converge towards offering features that help integrate all aspects of data sourcing within and outside their warehouses.
Multi Cloud Virtualization
Cloud computing services are increasingly being adopted by organizations.
David McNerney of Virtana provided insight that many users are adopting a "multi-cloud" strategy by selecting their cloud with both low cost and performance in mind rather than choosing just one provider at once. He commented, saying users may adopt multiple cloud strategies so as to find those offering both. He further commented, stating, "This also indicates we may see increased cloud migration; when one fails to meet price or performance targets, customers may opt for another more reliable one.
