Wondering if anyone has any experience or knowledge of some good, free, potentially open-source, cloud/Web Operating Systems that I can install and host on my own personal 2K8 R2 Server at home?

What are you trying to achieve that you think a "Cloud OS" will help? – Mokubai Jun 16 '12 at 11:13
So I can access an OS (customisable through my server with applications and storage) through any browser on any computer. – PnP Jun 16 '12 at 11:29
You are using a very expensive server 2008 license and look for 'something cloud related but free'? Really ? – Hennes Sep 10 '13 at 19:15
The cloud-wash gets in my eyes... What is a web os? Something I've probably been using for years that's been renamed somehow? – Fiasco Labs Sep 10 '13 at 19:59

It sounds like what you're actually after is a virtualization solution.

By installing something like VMWare or VirtualBox, you could have several customised "operating systems" accessible remotely running on your server.

e.g. You could have a Linux console-only VM, a Windows 7 VM with Office, and a Mac VM with Xcode all running on your server, and accessible remotely.

As far as accessing these through the browser, VMWare provides a tool called "vSphere Web Access", however it requires VMWare ESXi, which is not free.

VirtualBox supports it's own RDP protocol called vRDP, however it isn't accessible through a web browser, and vRDP clients seem to be pretty scarce.

More info on vRDP is available in the VirtualBox manual, ch 7.

Alternately, you could use an OS-native remote solution. Versions of Windows from XP upwards support Microsofts RDP protocol, and viewers are built into certain versions of the operating system.

Finally, probably the best route compatibility-wise would be to use a VNC client such as TightVNC

This is a multi-platform VNC client/server which specifically has a Java viewer, which will run on any computer running Java. The server also comes with a built in web server.

From their website...

The VNC servers also contain a small Web server. If you connect to it with a web browser, the Java version of the viewer will be downloaded automatically, allowing you to access the remote desktop. Obviously, your Web browser must support Java applets. Also, you should not use a proxy, to let the Java applet access the remote server directly.
