Improving the Quality for the End User
One student at a time… Recently, I visited a company that develops and distributes software for Independent School District’s across USA.

I have been asked by a colleague “Why would someone use Application Virtualization?” You may already know that adopting the likes of Application Virtualization is not an easy task. Many applications are simply not built to be deployed in such an environment. Not to mention all the other challenges faced within the IT organization. One [...]

Thursday, November 5, 2009
In the previous post we identified the Wide Area Network and the impairments that it introduces as a key reason for why a local user (let’s say in NYC) experiences a faster application than a user that is remote to his datacenter (let’s say in Tokyo).

Tuesday, October 13, 2009
This series of posts is about the day after a data center move. Now that the data center is remote, how does this paradigm shift impact the way we should develop, test, deploy, monitor and troubleshoot applications.

Earlier this week, Shunra announced the release of a new product, VE Desktop for HP Software 5.0.
