The Big Question

In planning and designing large-scale VDI, you might have questions or concerns about the features and ability of Raspberry Pi. To be specific, how well can Raspberry Pi function in a VDI environment? This is important, considering that it is one of the most affordable Thin Client computing options in the market. Does it offer the resources needed to support user demands in enterprise VDI? In fact, the low cost of this device has raised questions about its suitability for advanced use cases.

Food For Thought

To begin with, a Thin Client does not have to be high-priced to qualify as a true Thin Client. The Raspberry Pi is intended to make VDI accessible for everyone. This includes those companies that wish to implement VDI with a modest budget. Also, it is known that the Raspberry Pi was released as an educational platform for computing projects. With time, its affordability took it further in the market and attracted the IT community. In short, what you get is:

Cost-effective thin client software in Raspberry Pi which replaces fat client/desktop PCs and easily sees VDI through to completion.

Also, you would be surprised to know that there is more to this lightweight device than meets the eye.

Now, let’s look at the performance benefits which the Raspberry Pi can deliver for your business.

Business Benefits of Raspberry Pi

Today, companies are looking to use the Raspberry Pi in commercial-grade VDI plans. Even so, we must know exactly how much ground it can cover. Now, the Raspberry Pi device is designed to support small-scale VDI does not limit it as a complete solution.

How is this so? Some may believe that the Raspberry Pi is only suitable for personal use. This is indeed the case, and there are some common examples like using it as a:

  • Home automation controller
  • Gaming console
  • A device in which you can adapt to read emails, write documents and play videos.


Even then, the truth is that the Raspberry Pi offers so much more than just these. Let’s see what it can do in the workplace.

Firstly, you can use it as a troubleshooting solution. PC connectivity issues and malfunctioning components are common in IT systems. Luckily, you can easily resolve them by configuring Raspberry Pi to oversee industrial control processes. Also, you can proactively identify IT shortcomings by using it as an information security testing tool with network-penetration software.

Ever thought of using the Raspberry Pi as a small and low-cost server to manage light internal or web traffic? IT teams in SMBs often bring together a set of Raspberry Pi devices to function as a server. This not only eliminates the need to use regular servers for the same purpose. Companies can also save a good amount on monthly and yearly server costs.

Raspberry Pi as a Total Solution for Task Workers

Every VDI plan begins with profiling and grouping end users in a company. There are three types, namely task workers, knowledge users, and power users. To begin with, task workers generally carry out routine tasks using small-scale computer systems and applications. As a result, the programs they run are not exactly CPU or memory intensive.

On the other hand, knowledge users do more than simply run basic applications. The research, manage and make sense of valuable information on a daily basis. So, the level of technical functionality in their work is somewhat higher. What’s more, they multitask by running multiple software programs and lightweight web browsers.

Finally, power users need rich interfaces as they deal with heavy workloads, run advanced programs and use graphics-intensive applications.

Businesses must make it their goal to help these users focus on things that truly count. For this reason, VDI must facilitate smooth operations and task completion. Keeping this in mind, what we are about to discuss next is of high importance.

Although task workers perform repetitive duties using small-scale applications, they have equally important roles as knowledge workers and power users. For this reason, IT should deliver the same level of superior UX across user stacks so that their staff remains engaged.

Taking this into account, how can organizations set up Raspberry Pi to serve task workers?

Raspberry Pi is actually the best fit for this user group. Why is this so? Firstly, they do not need heavy processing functions. Next, their work involves relatively lower frame rates as compared to knowledge workers and power users. The Raspberry Pi works well as an embedded systems platform that users can configure to run tasks without codec decompression. You can also use it to get projects with low computational power up and running with only a few clicks. So, what you have is an ideal Thin Client for places with a large number of task workers. This is because it keeps VDI device investment and maintenance at a minimum.

Tip: knowledge and power users should go for higher-end Thin or Zero Clients. These solutions assist tasks that demand features like multiple ports and dual, triple or quad monitor support.

In any situation, proper VDI planning is knowing what features and efficiencies Thin or Zero Clients can realistically offer.

Raspberry Pi’s Immunity to Vulnerabilities

All businesses come across PC connectivity problems or faulty parts that lead to downtime and low productivity. The list also includes those that have solid IT systems built into their infrastructure. In such cases, adopting VDI is a good decision as it supports disaster recovery and true business continuity prospects.

For this, a VDI plan must be backed by a Thin Client solution with an intelligent and immune design. Fortunately, ClearCube’s Raspberry Pi 3 offers just that. You can use our Cloud Desktop OS to:

. Centrally oversee and virus-proof the Raspberry Pi 3.

. Secure its connection to centrally hosted applications, hosted desktops and cloud-hosted desktops. The Cloud Desktop OS embeds the Linux-based operating system which comes with its own security and management settings. You can also locally install the Cloud Desktop OS or begin network booting for a real Zero Client-like security experience.

Why is all this important? Generally, IT vulnerabilities can bring all IT systems to a halt by affecting their functionality. Two recent examples of the same are Spectre and Meltdown. Both use speculative execution to read private and sensitive data from running programs. Remember the Raspberry Pi features we discussed earlier? They amp up its resistance and resilience to malware and attacks from viruses such as these two. This also puts the Raspberry Pi among those solutions which ensure privacy policy best practices.

Raspberry Pi founder Eben Upton confirmed the device’s immunity to these vulnerabilities due to its state-of-the-art processors. They include the ARM1176, Cortex-A7 and Cortex A-53 cores. Note that ARM processors generally run on Zero Clients. Now, here’s the good part. Their addition in Raspberry Pi Thin Clients means that IT can use the latter to manage VDI with optimized efficiency. All you need to do is configure Raspberry Pi for maximum security. You then get a versatile device that supports information assurance and minimizes IT downtime.

Further Raspberry Pi Features and Capabilities

ClearCube’s Raspberry Pi Thin Client is the perfect solution for VMware Horizon set-ups. Integrating Blast Extreme into Raspberry C3Pi Thin Client decreases CPU consumption. The reason? Video decompression is offloaded to its native hardware from the CPU using an H.264-based decoder. This improves bandwidth and boosts performance in Horizon 7.1 settings.

The C3Pi Raspberry Pi 3 endpoint also features support for Microsoft RDP, CITRIX HDX, and many virtual desktops. All these are the makings of a true low-cost Thin Client that offers optimized performance in VDI set-ups.  

Introducing The C4Pi Raspberry Pi 4

The Raspberry Pi is well-known for its economic viability, versatility, portable size, and most importantly, innovation. With each iteration, the low-cost computer has earned its reputation as a powerful, reliable, and secure endpoint within an enterprise outlook.  As always, in keeping with our philosophy of custom-crafting hardware and management software solutions to the biggest IT challenges, we introduce the all-new and high-performance C4Pi Raspberry Pi 4. The device is a testament to our team’s ability to continue innovating on top of the Pi platform, which means maximum ROI for different industry verticals.

The C4Pi incorporates additional RAM to run Windows and demanding software. Companies benefit from considerably improved GPU, CPU, and I/O performance in a compact machine that offers real business value. A quad-core, 1.5GHz Broadcom BCM2711B0 64-bit CPU powers the C4Pi for a noticeable computer performance improvement over earlier versions. Robust graphics and multimedia capabilities facilitate a seamless user desktop experience in graphics-intensive apps while providing enough power to compete with entry-level x86 PCs.

Enclosed in an official ClearCube case that facilitates maximum ventilation and heat dissipation efficiencies, a heavy-duty fan provides the required airflow for passive cooling in time and mission-critical scenarios. The SoC comes with heat sinks attached to its top which decreases the risk of hardware failure from overheating. Previous-generation models of Raspberry Pi are known to experience heating issues that impact their throughput where the thermal sensor on the SoC reaches its pre-configured, maximum temperature (82°C). When this happens, the device automatically minimizes its clock speed to prevent thermal damage, resulting in what we call ‘thermal throttling’. The C4Pi solves this problem with simple heat sinks that integrate superior dissipation technology.

That is not all. Featuring up to 4GB of LPDDR4 RAM with the ability to output 4k video at 60 FPS, the C4Pi rivals many platforms, including the Citrix Workspace Hub. The latter, at its most basic level, offers businesses a Thin Client, proximity reader, and UEM management. Enterprises interested in this might not have liked that they required an extra device (a Pi Zero) to manage a second monitor. On the other hand, the Raspberry Pi 4, built on the Pi 0, integrates an impressive dual-view display. Moreover, going forth, such a device will not even be needed, hence presenting the Pi 4 as a more affordable and viable solution than ever.

Final Thoughts

The future of low-cost remotely managed Thin Client computers looks promising. In addition to VDI advancements, the ongoing need to reduce maintenance, support, and operating costs have kept the global market alive and thriving.
