Virtual Machines have always been a great way to work with different operating systems, carry your desktop around with you, and manage lots of servers or configurations. In the past, you’d run the virtual machine on your computer and then use a product like VMware Workstation or Player to interact with them.
In Workstation 8, we introduced the ability to share VMs across a network with other copies of Workstation, and to use VMs running on ESXi/vSphere. You could use any computer in your network to reach any other VM and to manage your servers. I covered this in a previous post, and as I said there, we were very proud of this release.
Still, the world is evolving fast, and more people are moving to tablets and smart phones. It doesn’t mean the end of desktops or servers, but it does change how people are accessing their data and applications. And their VMs.
I’ve spent the past few months on a prototype, one I’m proud to say we’re shipping as part of the Workstation Tech Preview. It’s currently called WSX (name may change in time), and it brings your VMs to your tablets, smart phones, and any PC or device with a modern browser.
WSX is installed as a mini web server in your network and serves up an interface for accessing your Workstation Shared VMs and your VMs on vSphere/ESXi 5. You can power your VMs on, off, suspend them, and interact with them. All from a web browser, and all without plugins, with nothing to install on the client end. This means that you can walk into the Apple store, pick up an iPad right off the shelf, and in less than a minute, start using your desktop back home. (Of course, provided you’ve port forwarded your WSX server so it’s accessible outside your network).
How does it work?
WSX makes use of some modern web technologies, such as HTML Canvas and Web Sockets, along with a small but powerful server to turn your browser into a full-on remote console. The WSX server talks to your Workstation, ESXi, and vSphere instances and relays the appropriate data up to the client running in the web browser. With that data, the client can stay updated with the latest changes to the VM and offer a full display of the console. We don’t use any plugins, meaning there’s nothing to install.
It’s known to work with the latest versions of Chrome, Firefox, and Safari. It also works with the Internet Explorer 10 preview (though I’m still working on some bugs there). And for tablet users, it works quite well with the iPad running iOS 5+. Android users running Ice Cream Sandwich may get some luck with Google Chrome for Android, but I’m still working on Android compatibility.
A lot of work has gone into making this pretty fast. If you stream a 720p YouTube video inside a VM and access it from Chrome or Firefox on a modern PC, you should see near-native quality and framerates. It’s not as fast streaming to an iPad just yet, but you’ll see some impressive changes there before long.
On some modern browsers, you can even make your desktop go full-screen, just like you can with Workstation.
Note: There’s a bug on the iPad today with the on-screen keyboard where capital letters and punctuation are a bit broken. I’ll fix it!
