The modern workforce is constantly evolving. Flexible work hours, remote working, anytime, anywhere access to corporate data, applications & resources from any device, are fast becoming baseline employee expectations. Organizations are also adapting and exploring better ways to work and collaborate, to boost employee productivity. While providing secure employee mobility is one goal, ensuring 24*7 support for always-on businesses, business continuity with minimal disruption in the event of natural calamities, or pandemics like Covid-19, are other drivers that are escalating the need for secure remote access for employees.
While providing employees with laptops or mobile devices is one option to enable remote working, it can incur heavy capital expenditure and more importantly, it can quickly spiral into a management and security nightmare for the IT team. With thousands of endpoint devices, disparate applications and data, and sophistication of cyber attacks, supporting secure and compliant workplace mobility can become overwhelming, if even effectively doable. With this said, let’s look at Desktop Virtualization as a viable alternative.
Desktop Virtualization is a technology that completely untethers a physical device from the desktop environment. Desktop components such as the hardware, operating system, applications, data, and user persona are moved into the data center, where they are centrally managed as individual components. When a user accesses his desktop from a remote device through the network, a dynamically assembled set of these components is presented to the user as a personalized view of his desktop, called a virtual desktop. The decoupling of the user’s device from his desktop environment enables desktop access from any of his computing devices.
Benefits of Desktop Virtualization
Simplified IT Management: Centrally located & managed computing and data environment simplifies IT management, and enables tighter control over endpoint devices, easier enforcement of security and regulatory compliance, and hence a lesser number of IT incidents. This process efficiency reduces operational overheads and drastically reduces costs.
Cost-Effective: Desktop Virtualization shifts organizational expenditure from CapEx to OpEx. When virtual desktops are hosted in the cloud as in Desktop as a Service (DaaS), costs are based on usage, making it very cost-effective.
Enhanced Employee Productivity: Employee mobility through secure access to the desktop, applications, and other corporate resources anytime & anywhere, fuels productivity.
Faster Disaster Recovery: This is achievable with minimal downtime since recovery does not involve rebuilding the physical infrastructure environment.
Rapidly Deployable and Highly Scalable: Virtual Desktops are provisioned based on role-specific preconfigured templates, and so can be spun up quickly depending on the demand curve. They can also be destroyed just as fast when not required, saving a lot of time, effort, and costs in anticipatory provisioning. Similarly, applications can also be quickly served, since they are centrally installed and controlled, lending agility to IT operations.
The abstraction and isolation of the desktop computing layers open new possibilities of workspace delivery. Different desktop virtualization technologies address different layers of the computing environment. Some of them over the years have been:
Application Virtualization, Virtual Desktop Infrastructure (VDI), Service-Based Computing (SBC), Client-Hosted Virtual Desktops (CHVDs), User Personalization Management (UPM), Workspace Aggregators, Remote Desktop Services (RDS) and many more. Desktop as a Service (DaaS) is a cloud-based service offering powered by one or more of these technologies.
VDI & DaaS have had the most innovation in recent times. VDI is a preferred choice since it remotely delivers the image of the desktop environment that users are comfortable with. VDI provides the highest levels of abstraction & security, among the technologies. In VDI, each user gets a dedicated thick client user environment run as a virtual machine (VM), and hosted on a server in the data center. The user works on the desktop image that is sent over the network and can then interact with the files, applications, and the OS, as he would in a physical desktop. The flip side to VDI is that the implementation and management need specialized technical expertise, so it would help to use a VDI vendor who offers end-to-end service as well.
In DaaS, the virtual machines are hosted on the cloud, and so it automatically comes with all the cloud computing benefits like flexibility, faster deployment, scalability, and affordable cost structure due to usage-based pricing, & the shift towards operating expenses.
GAVS’ VDI Solution
zDesk, is our end-to-end integrated solution for a fully functional VDI. zDesk combines the benefits of VDI and Desktop-as-a-Service (DaaS) and can be hosted either on-premise or on the cloud. The simplicity of the single-vendor solution enabled by hyper-converged and software-defined infrastructure technologies defies the rapid deployability, scalability and robust security of the virtual desktops.
