No equivocations on my part; the answer is a resounding yes. Today, there are multiple deployment models, but fast forward to three to five years from now, when cloud computing becomes much more mature, and we will see only two models survive. And neither will be VDI (Virtual Desktop Infrastructure).
But let’s back up and look at what we have today.
First, there are thick client applications, such as Microsoft Office – rich applications locally executed on a desktop OS to give users a fast, seamless experience. This type of application is not going anywhere and will be around for a long time because it offers a high level of dynamic activity that cannot be rendered for a Web-only interface.
Over the last few years, a new class of applications has emerged that run in the cloud – for example Google apps or Salesforce.com. These apps are fundamentally built for the cloud and built to run on browsers from any computer or mobile device. These aren’t applications built to run locally which are just thrown into the cloud. Google is leading the charge here, with Google Chrome increasingly becoming an operating system itself. IN the near future, these apps will co-exist with thick client apps and end-users will require environments that support both models.
Somewhere in between is the third model today: VDI.
Though its proponents may say otherwise, VDI is not a true cloud-based solution. The apps were not built to run on the Web; they require rich local execution. What VDI does, in the simplest sense, is allow IT managers to put a rich local execution environment on a server and deploy it as a “cloud app,” albeit a crippled one at that. It offers none of the performance and offline use you get with a rich app nor the simplicity of a Web app. At best, VDI is a stopgap solution; it exists because most enterprise apps were not built for the Web.
In five years’ time when apps that need to run in the cloud are in fact purpose-built for the cloud, you can bet that VDI will become obsolete. In the end, we will have only two main types of applications: Rich, locally run applications for end use points and a rich set of applications built for cloud computing. Rich local execution apps will persist because computing will not be 100 percent online (yet) due to connectivity and performance. Some apps, such as PowerPoint (however much you love it or hate it), requires rich interaction, and therefore is best fit as a local, OS-based desktop application.
Interestingly, the motivation for VDI was always about central control. If VDI, as a management layer, is out of the picture, then how do you ‘control’ and centrally manage these two types of apps? We believe for rich endpoints client-side virtualization is the way to go – allowing central management of the desktop while enabling rich interactions and offline use. For the apps in the cloud – existing datacenter management tools solve the problem.
What do you think? What will a mature cloud computing environment mean for VDI?
