The Virtualization Practice

Application Virtualization

Application Virtualization covers application layering and application delivery approaches like streaming applications, and local application virtualization. Infrastructure as a Service focuses upon isolating the operating system from its underlying hardware and allowing multiple instances of operating systems to share that underlying hardware. Application Virtualization focuses upon isolating application from their underlying operating systems. ...
This make it unnecessary to install applications into operating systems, makes it easier to update new versions of applications, and breaks the dependencies between versions of applications and the specific versions of operating systems. Popular application virtualization offerings include Microsoft App-V, VMware ThinApp, and the XenApp Plugin for Hosted and Streaming applications.

Browsium crafts lifeline for IE 6 users

Startup Browsium, is readying a lifeline for enterprise IT organizations that moving to Windows 7 but unable to escape their addiction to Internet Explorer 6. The Washington DC-based startup staffed by ex-Microsoft employees is planning to release UniBrows an add-on for Internet Explorer 8 that lets customers access IE6 dependent web apps from the now defacto standard that is IE 8.

There is great outrage to Microsoft’s reluctance to play ball and support virtualization of IE. Without an alternative, the solutions offered by Microsoft are expensive, cumbersome and difficult to maintain. Virtualising the application may well allow different browser versions to co-exist – but the user-experience can be cumbersome with links to other applications not always launching the correct browser and users having to know which browser to choose. Unibrows offers an interesting alternative utilising isolation to support the deployment of different controls and centralisation to allow management and control and importantly wrapped up in what sounds like a very appealing cost.

Application Deployment solutions reduce the cost of delivering applications and help you manage license use? With the end of support for Windows XP happening in 2014 many businesses are moving towards Windows 7 – ideally this inevitable cost is kept low. Application Virtualization can be used on ‘traditional’ desktops and laptops. Application Virtualization can be used in client side-hypervisors. Application Virtualization extends and increases the efficiencies of desktop virtualization as well as enabling portability and improving compatibility of applications. Application Virtualization can free you, not only from the limitation of having to “install within each device”, but lead the way in offering an alternative to “install on only corporate devices”. Application Virtualization can be a tool to reduce the complexity and time needed to move from Windows XP to Windows 7, and from future application updates. Indeed, for many companies, Application Virutalization is an option that can be used now by utilising existing license agreements, or for less cost than converting the application to run as a web-based service.

The Freemium sales model is a business model innovation best suited to inexpensive products that are very easily understood (and therefore not very new or very different) and that solve an obvious problem in a manner that is more convenient for the customer to acquire and implement. There are not many new virtualization and cloud technology companies who set out to produce undifferentiated products which suggests that a general application of the Freemium model to startups in our ecosystem is ill advised. Enterprise customers should pay great attention to products that are being marketing in this manner to ensure that they do not end up growing the use of something that was purchased in a tactical manner into a strategic use case.

On the heels of receiving United States patent approval for its RES Virtual Desktop Extender (VDX) technology, RES Software have announced that it will also be offering VDX as a standalone product. A feature within RES Workspace Manager (formerly RES PowerFuse), VDX serves as a fundamental component in the successful deployment of virtual desktops. It enables local applications that typically do not run smoothly, or at all, in virtual environments to run seamlessly within a virtual session. However, while VDX’s functionality allows wider access to hosted desktops, organisations need to ensure that the management and maintenance of that legacy environment isn’t overlooked to the point where it impacts user experience and the organisation’s security.

If we are going to start over, why not really start over and reinvent the entire infrastructure and management software industries in the process. That way we end up with an infrastructure that was actually designed for the dynamic, agile, and scalable use cases that we are trying to address with a green field approach, and an appropriate set of management tools as well. Is this going to happen? You can bet that there are already VC funded startups in stealth mode working on it.

Application Virtualization’s benefit is that your business application is no longer dependent on the operating system. Project GoldenGate is Citrix’s new offering to support application deployment to smartphones. Project GoldenGate may be a nice to have for some existing Citrix corporate customers, possibly for a SaaS vendor – but by the time Citrix mature this offering will either web applications work just as well on a smartphone, or will there be established development houses who can offer application that work directly on your company smartphone devices without the Citrix infrastructure and without the Citrix license cost?
