There is a general conception about VDI that it offers flexibility but brings in complexity and high costs. Is this true?
The answer is Yes and No. To understand this better, let us compare the advent of VDI solution with the Terminal Services, which served the technology until nothing was ever known about virtualization.
A decade ago, Terminal Servers were the synonyms for Remote Connection. The installation used to be a couple of minutes affair with TS or RDS systems, with single software installed on the host. Using one host meant the lower server licensing costs as well. The Remote Desktop Connection also offered brilliant savings on hardware purchase. PC numbers reduced down to couple of units while the thin clients dominated the IT environment in offices. The day to day activities were taken care of very well through the TS systems at relatively much lower costs compared to PCs. However, there were some aspects where the Terminal Servers failed terribly:
- PC like experience
This demanded the next level of computing, which could offer the transmission, personalization and security similar to that of a PC, while keeping the server number low. This idea gave rise to virtualization.
VDI, the server virtualization, took off with a great revelation. It promised all the characteristics which the users missed with Terminal Server systems. The actual server was divided into multiple virtual machines (VMs), each of which acted like an individual PC. The users could access and control their virtual machine with complete independence, and could even personalize their virtual desktops with no dependency whatsoever. The fast data transmission through advanced protocols even supported the high quality media in VDI. It was a great improvement, and the entire system seemed perfect, with one exception- the usual VDI system is complex in architecture with heavy costs involved. This is primarily because:
- It involves the installation of couple of virtualizing software apps. for creating and configuring VMs and Users.
- If a master image is used as a template for every VM for central patching or upgrade, there are more installations and configurations to save personal profiles on each VM.
- Multiple components are installed to get audio and USB redirection.
- More installations needed to support graphic rich frames like multimedia or animations.
- The more software and installations directly means more licenses for the VDI systems, which significantly raises up the system costs.
So, there is no denial that the deployment costs are much heavier in VDI systems, when there is too much management taken into consideration. This is true in case of large enterprises, which need all sorts of manageability options with their VDI systems.
But the schools and SMBs need not invest high to avail the similar benefits of virtualization!
In fact, the deployment costs for VDI solutions for SMBs and schools are at par with the PC set-up. Considering the needs of both of these industries, the purpose-built VDI solution works best to get the best of technology at lower costs. There are no stringent back-up requirements and no complex management tasks involved to control discrete processes. The VDI systems rather deal with the well defined scenarios which can be accessed remotely with speed and ease.
Sunde’s Zero Client VDI Solution For Schools And SMBs
Diana, the Zero Client VDI Solution from SUNDE promises the purpose built computing solution with personalization, isolation and PC-like experience with no compromise. It is recommended over the other vendors for very simple reasons:
- It is very simple and easy to install.
- There are no complex components to be managed.
- High transmission proprietary protocol from SUNDE ensures smooth performance like PCs, even for full frame multimedia.
- Affordable price, comparable to PCs
In short, with SUNDE’s Diana Zero Client come the benefits of VDI, at the prices which are similar to PCs.
So, coming to the initial question with a twist:
Is VDI deployment complex and costly for Schools and SMBs?
The Answer is NO!
