A thin client is a low power computer that can connect to other powerful computers remotely usually via VNC or RDP protocol and then it shows the screen of the remote computer on the display connected to the thin client. The USB devices connected to the thin client is useable from the remote computer that it is connected to. So, it's a very great solution for companies. Instead of buying separate computers for each of their employees, they can set up a powerful virtualization server and set up low cost thin clients that will connect to the virtual machines hosted on the virtualization server. This solution also makes upgrade easier as the computers are in reality virtual machines.

Now you know how useful thin clients are. Raspberry Pi is a cheap single board computer that you can set up as a thin client very easily using WTware.  In this article, I will show you how to set up a Raspberry Pi thin client. I will be using Raspberry Pi 3 Model B, but it should work on any model of Raspberry Pi 2 or Raspberry Pi 3. So, let's get started.

Things You Need:

To make a Raspberry Pi thin client, you need,

• A Raspberry Pi 2 or Raspberry Pi 3 single board computer.
• A microSD card.
• Internet connection and a Windows computer.
• A Monitor with HDMI cable.
• An Ethernet cable.
• A USB keyboard and a USB mouse.
• An Android phone charger for powering up Raspberry Pi.
