This article compares the demands of the schools, and is intended to help the management decide which is better for them. In short, this content targets in suggesting:
- What kind of schools has TS/ RDS more suited
- What kind of schools has VDI solution more suited
- The features of TS/ RDS and VDI solution enlisted
- The reason that makes Diana Zero Client an obvious choice for VDI

You are running a school that specializes in a few subjects with a limited number of students. Clearly, the applications demand is not diverse. The students need similar applications, similar standard of desktops to work upon and the technological needs are limited. You have worked upon the investment which should not exceed the limits, when purchasing the hardware and licenses for your computer labs.
You are running a school that offers various grades in learning- primary, middle and high schools for instance. There are a huge number of students, who have different learning needs. The technology required for primary, middle and high schools are very different from each other. You need various applications to offer the advanced education. You also need fast speed and rich multimedia as a part of a few classes involving entertainment oriented teaching. You can afford a high initial investment, provided that the long term savings on maintenance is considerably reduced.
The above two scenarios are very different from each other, and will help you to decide which form of technology you actually require- TS/ RDS or VDI !!
Scenario 1 and TS/ RDS:
Terminal Server (TS)/ Remote Desktop Services (RDS) is clearly the choice for the schools which do not deal with too much diversity. In other words, the advantages associated with TS/ RDS over VDI can be summarized as follows:
- There is a main machine housing the applications, memory and the storage. It is called the host or server where the processing takes place. The users which are connected to the hosting server are called ‘terminal users’. These users use only a part of the host resources and share the common applications. This reduces the costs of the hardware purchase and software licenses.
- Since the common applications are shared by all the users, the maintenance needs to be done only for the host. The software upgrades and Operating system patching for issue fixes is needed only for a single machine. This makes the overall management extremely easy.
- The architecture for TS/ RDS is comparatively much simpler than VDI. The deployment and management is easy and does not need any special guidance for the process.
However, the demands of the schools are completely different in case of the second scenario.
Scenario 2 and VDI:
Virtual Desktop Infrastructure (VDI) is the solution when the needs of the schools are not specific. With too many users, accessing entirely different applications, demanding a PC like experience is something that needs a better technology than TS/ RDS can offer. These features which are inherent in a VDI solution are listed below:
- With VDI, the students have an access to a more powerful desktop, which supports rich multimedia and graphics. TS/ RDS is far behind in this case.
- VDI’s support for the applications is better than what can be supported by TS/ RDS. This means that many important applications which can assist in the teaching and learning process are not supported by TS/ RDS.
- TS/ RDS has a sharing of the applications involved. This restricts the number of users connected to the server at the same time. In case of VDI, each user has a virtual desktop of his own, which makes it possible to have unlimited users connected to the server concurrently.
- Different grades can be served with their individual demands. Each student and member of the staff can have the applications which they require, with VDI. This is not possible with TS/ RDS due to the similar applications being shared by all users.
- A few of the features distinguish VDI, and helps in management tasks better. One such example is ‘Snap shot Technology’ feature, which can take the desktop to an instance in the past and use the result for error recovery, issue fix and back-up.
With VDI, the advantages outweigh the cost factors dramatically. If VDI is your choice, SUNDE’s Diana Zero Client is the solution that you will want to go for. Compared to all other VDI solutions in the market, Diana is the only cost-efficient, high performance and easy to deploy choice, that comes as a package offering all the needed components. This means less cost, no applications incompatibility and a very high performance.
There are no fixed rules governing which solution to opt for. The one that suffices your school demands is the one that is right for you.
