Running certain applications, such as CAD programs, often requires powerful hardware. Companies that need to make such software available to multiple workstations often face high costs due to the need for regular hardware upgrades. The cheapest solution is a terminal servers, which enables the central deployment of applications. But what exactly is a terminal server and what are they? Advantages and disadvantages? In this blog post we address these questions and summarize the most important information.

What is a terminal server?
in a terminal servers it is a powerful server where programs and data are centrally stored, processed and executed. Users can use terminals with the appropriate software to work on the server. Connected end devices are also known as clients.
A separate session is opened on the server for each user. The terminal server handles all data processing, and ultimately only an image of the program on the server is displayed on the respective client. The end device thus becomes an input/output device with which the user can use a remote server.
The advantages of the terminal server
Using a terminal server has the following advantages:
- More flexibility: Users can access the terminal server and use the virtual workplace anytime, anywhere. Consequently, it is irrelevant whether the user is in the company or in the home office. Depending on the client software, a smartphone or tablet can also be used to access the server.
- Less effort: Since the IT staff only has to maintain and update the server, and therefore not multiple devices, using a terminal server is associated with less time and money.
- More security: Instead of monitoring cyber threat protection with multiple end devices, IT security can focus on a single device. Security guidelines, firewalls and backups should only be centrally implemented and lead to better protection of the IT infrastructure.
- Easy outsourcing: The maintenance and location of the terminal server can easily be outsourced to an outside company. In this way, investments in hardware can be kept low. If necessary, it can be combined with other IT services.
The disadvantages of the terminal server
The following disadvantages may be associated with a terminal server:
- High latencies and large data loads: Most connections are sufficient, since normally only image information is transmitted from the server to the client. However, as soon as the user is also supposed to be able to transfer data to the end device or print something, a higher data load and thus high latency can arise.
- Higher server costs: Sometimes graphics-intensive applications often require powerful server hardware, which is associated with a correspondingly high investment. With server rental, this cost element can be greatly reduced due to the high level of standardization between providers.
- Internet Compulsion for Jobs: If the server is not located in a company-owned building, communication between the client and the server requires an Internet connection. The same applies to working from the home office. Provision can be made by providing a second Internet connection, for example through an access point. Alternatively, at least one office pack even panorama installed locally on the client, but this approach softens the general concept a bit.
Cost: These aspects must be weighed against each other.
Classic client-server models are not necessarily more expensive than virtualized desktops. in a terminal servers In addition to the costs of good server components, there are also server access licenses to consider. Weaker hardware can be used on the client side for this. In addition, the time and costs of maintenance and upgrades are reduced with a terminal server.
Conclusion: Ideal for companies with multiple locations
Terminal servers are a good alternative to a large arsenal of single-user computers. Users are more flexible and mobile, need less support from IT, and can complete tasks faster. Not only corporations, but also small and medium-sized businesses can afford the technology. Terminal servers should be considered especially by companies with multiple locations. Central administration of data and applications can help streamline the structure of the company.
