Mobile thin clients may be a somewhat niche option as endpoints for VDI deployments, but they can deliver many benefits in terms of security and simplified management.
A thin client is a stripped-down endpoint that lacks the bells and whistles of a traditional PC or laptop. Some examples include the Raspberry Pi, Google Chromebook and Dell Wyse. In fact, thin clients are the most common device VDI shops use as endpoints at 38%, according to Login VSI and Frame's "State of the EUC 2018" report released in May.
Mobile thin clients take things a step further because they only provide users with access to their virtual desktops and nothing else -- on the go. They are ideal in situations where many users within an organization work outside the corporate office.
How mobile thin clients work
IT can turn traditional laptops into mobile thin clients by replacing the hard disk with a solid-state drive. This move should boost battery life for the device. In addition, IT pros can use an embedded OS -- either Windows or Linux -- to manage the OS in a central management console along with the rest of the deployment. It also prevents users from downloading any of their own apps locally.
Advantages and drawbacks of mobile thin clients
Any organization that works with highly sensitive data or must meet strict compliance guidelines should consider using mobile thin clients, because they can allow users to securely access resources from any location. In addition, because no data lives on the mobile thin clients themselves, IT only has to worry about securing the devices and the network. IT can also deliver a fully locked-down OS to mobile thin clients and manage it from a central location.
A lost or stolen mobile thin client can pose a risk to an organization because it does serve as a pathway into the corporate network. As a result, IT pros must use a remote management product so they can shut a device down or wipe it remotely.
Mobile thin clients are beneficial because users can access their desktops as long as they have an internet connection. They also have more power than simply delivering virtual desktops to tablets or other mobile devices, so resource-intensive corporate apps generally function better.
On the negative side, mobile thin clients strip users of flexibility and control over what they have on their desktops. In addition, performance is completely dependent on the network.
A few options on the market
If IT isn't up for converting existing laptops into mobile thin clients, there are several choices on the market to buy these devices from companies such as HP Inc. and Dell. Here are a few examples:
HP mt21 Mobile Thin Client comes with a 128 GB flash memory drive, an optional fingerprint reader and several ports for users to connect to projectors, charge phones and more. It works with Windows 10 IoT Enterprise and the HP ThinPro file-locking system. The base model costs $449.
HP mt20 Mobile Thin Client is slightly cheaper at $399 and also runs Windows IoT Enterprise as well as HP ThinPro OS, which is Linux-based. It comes with Windows Unified Write Filter, a security feature that prevents unauthorized updates from running on the device. It also integrates with some management features, including HP Device Management and HP Velocity.
Dell Latitude 3460 Mobile Thin Client uses Windows Embedded Standard 7 as its OS, which gives users the ability to work with many Windows applications and peripheral devices. It also has an integrated HD graphics engine. IT can manage it either on-premises with Wyse Device Manager or in the cloud with Wyse Cloud Client Manager. Dell's line of thin and zero clients start at $329.
Mobile thin clients can also take the form of HDMI dongles or USB drives. Users simply plug them into a device with the compatible port.
This type of mobile thin client allows users to work with older hardware, because the user is really accessing the virtual desktop or app through the tiny thin client device, not the laptop, PC or monitor he is working on.
IGEL's UD Pocket, a Linux-based thumb drive, is an example of such a mobile thin client. Users just plug the UD Pocket into a USB port and enter a key that IT provides, and they can access their virtual desktops and apps.
