Virtualization: The Road to App-iness

Virtualization
Learn how ‘Application Virtualization’ drives data sharing in the virtual desktop environment.

Applications are the way users get their jobs done.  Application delivery is different for legacy Windows applications, web applications, mobile applications, and cloud framework applications. 

Legacy Windows applications require application virtualization to be streamed from a cloud-like resource.  Application virtualization is a companion to desktop virtualization.  Instead of installing an application on a user desktop, the application is “installed” in a standalone format that can be streamed from the data center.  Application virtualization basically tricks the software into thinking it is running on Windows.  Though, not all legacy Windows applications can be perfectly virtualized.  This Application virtualization will not run as a web application, mobile application, or cloud application.

Web applications are also a companion to Desktop virtualization as they are inherently device agnostic, and can run be run through a virtual desktop browser.  However, web applications typically create a tension with browser version support.  It is expensive to keep re-certifying web applications against ever changing browser releases.  Web applications can store a significant amount of data and plug-ins in user profiles, which puts an additional cost and performance burden on cloud-hosted desktops.

Mobile applications coming from mobile “app-stores” and cloud framework applications (like Hadoop) are emerging and improving all the time.  In some cases, these apps may bypass the need for desktop virtualization at all.  The key clarification to be aware of is that legacy Windows application virtualization is NOT compatible with either mobile applications or cloud framework applications – that will require additional development and testing.

Mission Focus

As a customer of desktop virtualization, focusing on user experience and cost reduction are the keys to success.  Driving profiles, applications, and data into cloud-like hosting is a good idea for many mission-focused enterprises.  By understanding the realities of virtualizing operating system hosting, cloud hosting, and application delivery, you will be able to help drill down and decide if “going virtual” is truly the right fit for your enterprise.
