Opinion: Enterprises Must Embrace Linux And Grid Computing

Look ahead to grid computing and open source or you'll be left to deal with a morass of legacy systems, Lou Bertin says.

My friend Jack has a headache. He sat slumped with chin on chest during a recent InformationWeek roundtable and, far from being the lively, insightful presence I've come to know and admire, he looked every bit a man in considerable pain. Jack's the IT director at a company that sits in the lower middle of a global value chain that, at the top, has companies that manufacture the conveyances that transport people and things via land and sea and air. His company is in the middle of things but is hardly the top dog in terms of dictating standards to partners.

So it was that when I interrupted his self-contained lamentations during a conversation about gathering and sifting and delivering management information from multiple individual sources, he lifted his head and half-croaked, half-growled the following: "Right now, I have to support 12 different platforms. Have to. The companies we do business with aren't going to change their platforms to suit us. And my management isn't going to spend a penny on integration as long as things are working.

"I can make a case for efficiency, but all they see is the spend, not the benefit. Right now, they're not exactly interested in spending."

His statement alone bears commenting upon (and we'll get to that later), but the rejoinder that followed was the crystallizing moment of that particular conversation. That speaker was an ex-IBM'er who confessed: "I worked at IBM for 30 years and we had a lot to do then with creating the problems you're facing today." The unvarnished truth, spoken simply and neatly, summed up the causes of many (if not most) of the technology migraines afflicting so many companies and institutions.

To be sure, the platform propagation that took place in the pre-Windows world was an unavoidable consequence of the technologies and technology realities of the day. The notion of desktop business computing even into the mid-'80s was beyond the grasp of most. The model was simple and linear and was built first, last, and always around customized code written for a single, proprietary platform.

Do those archaic technology investments continue to deliver value? Apparently so, based on the observations from the majority of you I speak with regularly. Legacy systems, viewed intramurally by their enterprise proprietors, are sources of immense value. However, legacy systems, especially when shoehorned into extramural value chains that were inconceivable when those systems were installed, can represent elements at the fringes of one of the seven circles of hell.

We're seeing new titles in this digital revolution, new responsibilities, new business models, and major shifts in technology spending.
