Microsoft Office is a good example. Organizations can host Word, Excel, PowerPoint, Visio, and other Microsoft software centrally with App-V, but because the applications are walled off from each other common tasks like embedding a table of data from Excel into a Word document couldn't be accomplished.
Microsoft solves that problem in App-V 5.0 with a new feature called Virtual Application Connection Group. An IT admin can group applications together in a Virtual Application Connection Group to enable them to communicate and work together. This new feature makes it easier for organizations to rely on App-V to deploy software and provide users with an environment that works just as they'd expect with locally installed software.
With App-V 5.0, Microsoft also addressed another problem behavior of virtualized apps. Past versions of App-V registered specific file types rather than broad capabilities. So, an "MP3" file might be registered to open in an App-V hosted Media Player, or certain file types might be linked to an App-V hosted email client, but media files or email content that didn't match the specific file types would be handled locally in Windows.
Virtual Application Extension in App-V 5.0 allows the App-V virtualized apps to register in Windows just as locally installed software does, so the App-V software can become the default application for Windows in general rather than just for specific registered file types.
App-V 5.0 also has some new tricks for IT admins. A management interface built on Silverlight enables IT admins to monitor and maintain App-V from just about anywhere via the Web. A Web-based management framework gives IT admins more freedom than being tied to a specific console.
App-V is developed with Windows PCs in mind, but App-V can also deliver Windows desktop applications to virtual desktop infrastructure (VDI) environments. There are no alternate platforms officially supported by Microsoft, but using a third-party VDI platform like Citrix, organizations may be able to deliver Windows software to Mac OS X or Linux, or possibly even to mobile platforms like iOS and Android.
App-V is just one tool in the MDOP arsenal, but it's a powerful one. App-V 5.0 includes many significant improvements that simplify application virtualization, and make it even easier for organizations to deliver a familiar consistent experience for users from a virtualized App-V environment.
