Virtualisation can ease desktop application deployment in a variety of ways.
It separates the application not just from the underlying hardware but also from the operating system. It means, for example, that you can run applications – or several copies of the same application – side by side in separate virtualised spaces without fear of clashes between them or with the operating system.
Seen primarily as a desktop technology, virtualisation offers the key advantage that because applications are independent of the client architecture you can deliver them in different ways, depending on the user's needs.
Just an illusion
They can be installed within their own virtualised space on the client, or they can be streamed so that the user sees only an image of the application, with almost no code downloaded. Applications can be deployed quickly and managed centrally so users stay abreast of security patches and other updates. Read more...
If you've already virtualized the servers in your data center, desktop virtualization may seem like the next logical step. But businesses are finding that the benefits of hosted virtual desktop technologies are more nuanced. The advantages may be harder to quantify and harder to justify based purely on traditional ROI calculations.
So, how do you calculate and quantify those advantages, choose the right technology and build out a successful hosted virtual desktop infrastructure (VDI)? Computerworld asked consultants, analysts and users who have been there to report on what works, what doesn't and how you can learn from their experiences. The first place to start, they say, is with a clear-eyed understanding of the potential benefits. Read more...
