The novel technology that is developed to host desktop environments on a centralized server is called Virtual Desktop Infrastructure (VDI). VDI deploys this service to end-users according to their customized requests. In simpler words, it is a kind of desktop virtualization where a specific desktop image runs with VMs (Virtual Machines) and is delivered over a network to the end clients. Those endpoints can be any device like thin client terminals, PCs or tablets, etc.
The term “Virtual Desktop Infrastructure” was originally coined by VMware and since then it has become a tangible technological acronym. The notion of delivering desktops and virtualized applications to the users falls under the category of End-User Computing (EUC). Though, windows-based VDI is the most common workload in the technological landscape, but Linux Virtual Desktops can also be considered as an option.
Depending upon the organization’s configuration, the user’s access to the VDI can be determined. It can also range from requiring the user to choose the virtual desktop and then launching it to the automatic presentation of the virtual desktop. Once the user has access to the virtual desktop, it takes prime focus but the feel and the look are that of a local workstation. The user can then select an appropriate application to perform their work on.
In VDI, a part of hypervisor servers into VMs (virtual machines) will, in turn, host virtual desktops. Users can access these virtual desktops from their personal devices and location but, all the processing would be done on the host server. By making the use of a connection broker (a software-based gateway that works as a liaison between the server and the user), users can connect their desktop instances.
In all the deployments related to VDI, the following features apply:
In today’s digital workspace, applications and files can be accessed on-demand. Virtual Desktop Infrastructure is developed to facilitate convenient and secure remote access that will help to boost the productivity of the employees.
Organizations should consider implementing VDI in an HCI environment because its scalability and high performance are organically for the resource needs of the VDI. The best practices to follow during the VDI deployment are:
Although VDI is a bit complex, still it offers numerous benefits to its users like mobility, flexibility, etc. Take a glance below:
In the persistent VDI, a user will always log into the same desktop image where all the changes in the data and the applications will retain. This will allow space for full personalization. Following is the way in which persistent VDI works:
In contrast to the aforementioned features, nonpersistent VDI works in the following approach:
The IT department does not have to maintain a large number of OS images that are customized because nothing is saved once the connection is terminated. This will allow a simplified data center management and will also reduce the costs. Nonpersistent will also streamline the management of devices for task workers who don’t save anything while working.
A generic term, desktop virtualization is any technology that will separate a desktop environment from the hardware that is used to access it. It can be executed in numerous ways, for instance, Remote Desktop Service (RDS), in which users can connect to a shared desktop that works on a remote server. Whereas VDI is a type of desktop virtualization. It is an alternative to other types of virtual desktop delivery that incorporates hosted shared solutions.
The technology the backs up and powers the VDI is Virtual Machines. Created exclusively by dividing a physical server into multiple virtual servers, VMs are software machines that can be used for a number of applications.
Application-driven, digital workspaces are straightforward and secured. Within them, you can enjoy access to numerous applications. An economical and reliable VDI solution will help in scaling key services and applications to today’s increasingly remote and mobile teams. VDI is developed to deliver a consistent experience across all devices including smartphones, tablets, PCs, etc. They offer a high degree of freedom to contractors and employees in terms of their working experience. It allows a more unified and streamlined workflow.
Here are some potential limitations of the Virtual Private Network:
Not only VDI is developed to reduce the overall costs but it will improve cybersecurity. VDI’s centralization and isolation is a pivotal aspect in offering multilayered security in today’s era where data breaches have become common and costly. It also spares from the complications of IT and from sensitive data being stored locally on the devices of the client.
