Don’t be held hostage to legacy IT (#3): That Pesky Hardware

chained to computer.jpgBy:  Tom Klinect, Application Modernization Consultant, Hewlett Packard Company


You’ve rationalized your application landscape and have a vision of where you need to go; however you have not even looked at you hardware infrastructure. Your systems are old. Your ability to support some of them is a challenge and others are just too expensive. You have to squeeze more out of your hardware today and what you have just won’t allow you to do that. You have heard about cloud, in fact you have heard about private cloud, public cloud, on premise, off premise, shared resources—just way too many terms to understand what to do.


You look around and you have a little of everything: Solaris, SunOS, HPUX, AIX, SCO, Tandem – the list just continues to go on and on. Oh, and don’t forget about that entire Windows footprint you acquired during some of your more recent acquisitions-- even that is old. Your software runs on these systems and although you have a plan to shrink your enterprise software footprint, how can you transition all of these disparate systems onto something manageable? You could move everything to a single cheaper platform. You could reduce the number of each class of hardware you have. That would save something but probably not enough. You could “virtualize” you software onto the remaining platforms.


You’ve heard of this thing called “virtualization” and some of the older hardware manufacturers have even implemented something called “zones” which allow you to break up your physical box into multiple virtual computers. However this technology requires you to keep, and in some cases upgrade your hardware. Now you are extending the life of highly specialized and expensive hardware. This seems counter-intuitive to your plan for reducing costs. This may be a solution once you have rationalized all of your software and shrank your physical footprint, but for now we’ll leave that “zone” idea on the back burner.


So you like the idea of cloud. You’re still not sure what it really is but it sounds better than your current monolithic systems. As you have your staff research cloud you find that it is something that grows and shrinks with demand. It uses virtualization and physical hardware to accomplish the task of running your enterprise.


So how do you take your monolithic infrastructure and start on your journey to the cloud?
