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.
There are many considerations when moving applications from on-premise to cloud. It is critical to understand the benefits and also challenges of this migration. A successful migration will result in lower Total Cost of Ownership, yet offer the same or higher level of robustness. In his session at 15th Cloud Expo, Michael Meiner, an Engineering Director at Oracle, Corporation, analyzed a range of cloud offerings (IaaS, PaaS, SaaS) and discussed the benefits/challenges of migrating to each offe...

Take the Long View with Digital Transformation By @IoT2040 | @ThingsExpo #IoT #M2M #API #Microservices #InternetOfThings
Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...
