Remote display and control technology is nothing new. For decades we've had the ability to remotely access and control our desktops using a variety of technologies and protocols: X11, VNC, RDP, and Terminal Services to name a few of the more well-known.
Remote display and control has been used for a variety of purposes not the least of which is the IT administrator's need to remotely root around on your desktop to troubleshoot an issue.
VDI is not the same as remote display and control, though many neophytes might understand it that way. VDI in general requires some form of client application; a client application that currently does not exist for every possible end-user client computing device. Thus VDI is not universally supported on mobile devices, despite a (apparent) desire by end-users for just such capabilities.
The choices for vendors of VDI technology are support an ever-increasing array of devices (and operating system versions) or find a device/operating system agnostic technology with which to deliver the desktop experience on a mobile device. Zero-client technology, as many are wont to describe it as. It's really reinventing remote display and control with technology better suited to unmanaged, widely variable endpoints using near-ubiquitous protocols, like HTML.
Hidden among the new features and functions for VMware Workstation 9 is one such "new" wheel: WSX.
WSX is a prototype of a new VMware Workstation web interface that enables users to access their Shared virtual machines via a web browser on a tablet, smart phone or PC without installing any additional applications or browser plug-ins. This service renders an HTML5 web page that can connect to your Workstation hosts, enumerate the available Shared virtual machines and allow you to power them on and interact with the desktop. Both the Windows .msi and Linux .bundle installations are available for download along with VMware Workstation 9.0
WSX is currently not supported for production environments. The number of devices and browsers available on the market make it extremely difficult to test this feature thoroughly to ensure it works well everywhere.
This feature requires a very modern browser that supports HTML5 with WebSockets. VMware recommends using the Google Chrome 17 browser on PCs and the Apple Safari 5 browser on Mac OS hosts and iPads. Currently there are issues using this feature with Microsoft Internet Explorer 10. WSX may work with other browsers and on Android tablets running Ice Cream Sandwich with the latest version of Google Chrome installed, but more testing is required.
WSX is a web server, a proxy, enabling access to your virtual desktop (provided its running on vSphere/ESXi 5). Clients communicate via WebSockets (HTTP) and the display is rendered via HTML5 graphic elements.
VMware clearly indicates this is a prototype, and lists a number of caveats regarding current limitations, but given that similar technology (Web Sockets and HTML5) is used elsewhere in production VMware solutions it seems clear that this early entry into the zero-client VDI game will continue to evolve and mature into a production-ready solution.
But what about …
Good questions, and ones for which there are currently no good answers. The use of WebSockets as a transport medium for what is essentially proprietary protocols crossing domain boundaries is problematic. While access control can ostensibly be handled by existing solutions providing secure remote access today (WebSockets is, after all, initiated via HTTP which has a variety of means by which authentication and authorization can be enforced) integrity of the data may be an issue as well as the potential for exploitation of the web server providing the proxied WSX service as intermediate devices would not be able to parse let alone recognize anomalies in the actual data exchange.
Scalability would be constrained to layer 4 (TCP) due to the lack of meaningful (and open) data at layer 7 (application) upon which intermediaries could manage flows and sessions. Persistence to an existing WSX server would necessarily revert to decades old techniques such as IP/Port combinations that have long since proven to be problematic, particularly as such schemes tend to result in unpredictably uneven load distribution.
There are a variety of issues raised by the use of WebSockets across networking domains in general, and as a means to enable remote display and control these issues are no different. The advantages, of course, lie in the ability to define a protocol specific to the application (in this case VDI "light") and use a single, long-lived asynchronous control layer that has significant benefits in terms of performance.
If the trend toward leveraging HTML5 and in particular WebSockets continues, then WebSockets will likely turn out to be one of the more disruptive technologies on the networking market since … well, since HTTP.
WebRTC services have already permeated corporate communications in the form of videoconferencing solutions. However, WebRTC has the potential of going beyond and catalyzing a new class of services providing more than calls with capabilities such as mass-scale real-time media broadcasting, enriched and augmented video, person-to-machine and machine-to-machine communications. In his session at @ThingsExpo, Luis Lopez, CEO of Kurento, will introduce the technologies required for implementing these ideas and some early experiments performed in the Kurento open source software community in areas ...

Containers are not new, but renewed commitments to performance, flexibility, and agility have propelled them to the top of the agenda today. By working without the need for virtualization and its overhead, containers are seen as the perfect way to deploy apps and services across multiple clouds. Containers can handle anything from file types to operating systems and services, including microservices. What are microservices? Unlike what the name implies, microservices are not necessarily small, but are focused on specific tasks. The ability for developers to deploy multiple containers – thous...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
