To virtualise or not — that is the (rhetorical) question


Ken O'Hagan is director of software presales at UK&I at Hewlett-Packard.


Today we are facing more and more complexity in our IT landscapes. We are forever bolting on newer, faster, cheaper solutions to deliver business services. Also, as if that weren’t recipe enough to give us night terrors, we continue to layer on top of existing systems—be they back-end transactional, data repositories or utility services—to be able to reuse as much as possible.


The challenge is that as the next major project comes along, we then have a dilemma around how we test a new solution in preproduction. What’s worse is that we don’t always have control of those systems to be able to test against them. Even more worrisome is that we don’t want to be firing test transactions against any live systems for fear of loss of integrity—or the inevitable "There is no one left who knows how it works, don't touch it!"
