Like most people, I’m a sucker for a compliment. So, when I received one via e-mail in response to my June/July column on “Ethical Computing,” I had no choice but to respond to the writer of those kind words. She wanted to know whether I had ever seen a job description for a business solution integrator. I told her that I had not, but that this would make a good topic for a future column, so here we go…

Licensing Software for Capacity on Demand

In recent years, awareness of capacity on demand (CoD) and utility computing has increased significantly. Many hardware manufacturers provide systems with variable hardware capacity, which allows customers to purchase base capacity and request additional capacity when needed to satisfy their “on-demand” needs. By their variable-capacity nature, these systems have strained standard software licensing models, especially those that are capacity-based. This article examines these strains and proposes a solution that will allow software vendors to license software in a simple, equitable way, while addressing customer needs.

Has Open Storage For zSeries Finally Arrived?

What’s old yet new, black and not blue, supports Linux, FICON, and open storage interfaces, too? Well that would be an IBM zSeries mainframe. I recently saw an interesting cartoon that showed Unix being squeezed out by Windows and Linux environments. Also in this cartoon were the banners of other ousted systems and technologies, including mainframes. While Unix was long hailed as the operating system that would put the final nail into the mainframe’s coffin, it is clear that the zSeries processor family is very much alive as are z/OS and Linux. This article examines how various open interfaces and technologies coexist and are part of a zSeries environment today that is very much alive…

A Survival Guide for the Outsourcing Age

The loss of domestic IT jobs to offshore outsourcing is real, large, and will only get worse with time. According to several industry sources, last year, Indian outsourcers alone delivered more than $8 billion worth of IT services. When compared to U.S.- based salaries, which are two to three times as much, the math becomes clear—$16 to $24 billion worth of IT payrolls suddenly disappeared from U.S. and Western European domestic job markets. This situation is further aggravated by the growing number of offshore outsourcing providers in Russia, China, and a dozen more aspiring contenders in the world’s outsourcing game…

Computing At The High End of The High End

Paul Mercurio, Mobil Travel Guide, Park Ridge, IL, will probably be the first CIO on his block to move to the IBM z990, the new high end of IBM’s biggest mainframe line. And, if everything works as expected, Mercurio and his customers, the travelers who pound away on the company’s Website, won’t notice a thing. “I guess it gives us more headroom than we could ever anticipate,” he notes…
