VDI Thin Clients: Unveiling the Comprehensive Handbook

High-end computing back in the day required large computers that used to take up a lot of space, adding to a lot of investment. Thin clients were introduced to move computing on a lightweight device from a full-sized PC. Thin clients, since then, have changed a lot. In today’s environment, thin clients are more straightforward, compact, windows-less, low-end systems fueled by Thin Client Operating Systems. Since these end-point devices do not have many spaces, they can’t hold sensitive data and applications. 

These devices are designed to perform computing over the cloud. Hence, all they need is an internet connection and a browser. Data from this computing is stored in data centers located in the cloud or on-premises. Its’ sole purpose is to display the result on a screen as close as possible to a standard PC. Thin clients first appeared in 1984 and were used to execute display server software.

What is VDI Thin Client?

A VDI (Virtual Desktop Infrastructure) thin client is a lightweight endpoint device that is specifically designed to connect to a virtual desktop environment. Unlike traditional desktop computers, a thin client relies on a server-hosted virtual desktop infrastructure to run applications and access files. It does not have a local operating system or storage capacity, as all the computing resources and data reside on the server. Thin clients are cost-effective and easy to manage since they do not require individual software installations or updates. They provide a secure and centralized approach to desktop computing, enabling users to access their virtual desktops from any location while minimizing the risk of data loss or security breaches. Thin clients are ideal for organizations seeking a streamlined and efficient solution for deploying and managing virtual desktop environments.

History of Thin Clients

Although the term thin client was formulated in 1995, this type of computing has its roots in multi-user systems. Multi-user systems are devices that multiple users can access. These systems have then evolved from executing command line interfaces to fully performing graphical computation (GUI).

In the current environment, thin clients are used to perform minimal display functions and to offer a platform that is combined with the latest cloud technology, allowing its users to perform high-end computing. These systems are highly inexpensive, relying primarily on servers to perform evaluations. Citrix, Unix, and Raspberry PI are some of the most known developers creating the most efficient thin client systems.

Businesses that support remote working environments can get the best out of slim client computing technology. This is where distributors like Raspberry Pi came into the picture by offering affordable and compatible devices. With the help of ACE VDI, enterprises can implement Raspberry Pi or other such systems to create a remote-friendly working environment.

How Thin Client Works

Thin Clients can be implemented via three different methods: Shared Terminals, Desktop virtualization, and browser-based approach. Shared terminals on thin clients consist of a common server shared across every user performing computing using a thin client. This limits the number of complex computations that can be achieved in a normal PC.

Desktop Virtualization allows IT experts to host an actual desktop-like presence on a virtual machine. The resources in a VMs server are not shared resources yet are still located in a single remote server. 

The browser-based approach is a little different from any of the above-mentioned techniques. In this framework, all the computations are done on a browser instead of on a server, which allows users to retrieve data and software on thin clients.

Benefits of Thin Clients

There are numerous thin clients benefits that can be leveraged in creating a remote yet secure environment while ensuring the power of computation is not hinged for users. 

  •  Less Expensive: As these clients do not have the critical components of a CPU, their costing reduces dramatically. Without a hard drive and a GPU processor, the cost can be brought down significantly.
  • Easy to Scale: On a requirement basis, Thin clients can be easily scaled up or down. Introducing an external hard disk, security tools, GPU or any other computational framework is easy and can be performed over the cloud as well.
  • Secure: Since there is no data storage or memory within thin clients, these systems become more invulnerable to external attacks and threats.
  • Less Power Consumption: Most of the thin clients are fanless. Some can even be held in the palm of a hand. With less memory and a smaller mechanism, lean clients generate less waste in the form of heat.
  • Easily Managed: Most of the software installation, addition, updating, or modifying any file or data is carried out on a server.  Moreover, these files are stored on a centralized server making it easier to retrieve and manage overall

Thin Clients Vs Thick Clients

As per the basic difference, Thin clients are just small device with no computation power of their own and relies on hosts’ resources. Whereas, a thick client is a full-fledged PC that does not depend on any other device for performance. 

Thin Clients, being smaller, are cheaper, easy to handle, and mobile. Hence, these systems are a perfect fit for remote working from anywhere environment. On the other hand, Thick clients are bulky, consist of all the CPU power, and hence are costlier and not so remote-friendly. 

There are many differences related based on their size, functionality, and use cases: 

Factors Thin Clients Thick Clients
Data Storage On Server, Centralized data management Local Storage, can be scattered among multiple desktops
Network Latency Requires High-Speed network coverage Can work in low network areas. 
Deployment Easier Deployment as all the clients are connected centrally Expensive deployment as multiple systems needed to be calibrated separately
Security Highly secure Vulnerable to data leaks and external threats

Thin Clients Vs Zero Clients

Thin clients and zero clients are both types of endpoint devices used in virtual desktop environments, but they differ in their approach and functionality.

Thin clients are lightweight devices that rely on a server-hosted infrastructure to run applications and access files. They have some processing power and storage capacity but still offload most of the computing resources to the server. Thin clients require a thin client operating system and often support multiple protocols for connecting to virtual desktops.

On the other hand, zero clients are even more simplified devices with minimal processing power and no local storage. They depend entirely on the server for computing resources and require no local operating system. Zero clients are purpose-built for specific virtual desktop protocols and are typically easier to manage and deploy compared to thin clients.

While thin clients offer more flexibility and support for various protocols, zero clients provide a streamlined and cost-effective solution with lower maintenance requirements. The choice between thin and zero clients depends on specific requirements, infrastructure, and management preferences in a virtual desktop environment.
