BBCWatcher writes: The Register's headline is a little misleading (mainframes are also UNIX machines), but the basic facts are these: BC Card, Korea's largest credit card company, is ejecting its many HP and Sun UNIX servers, and Oracle databases, and replacing them with (undoubtedly fewer) IBM System z10 servers (a.k.a. "mainframes") running z/OS, CICS Transaction Server, DB2 for z/OS, WebSphere Application Server for z/OS, Java, C/C++, Tivoli and InfoSphere software, etc., for its next generation credit card processing applications. IBM dropped the bombshell before Christmas, but the (stunned? vacationing?) Western IT press is only now waking up to recognize its significance. Sayeth BC Card's CIO, JeongKyu Lee: "We chose System z for its continuous operation, service quality made available through IBM's mainframe software solutions, and economic returns for the years ahead." Likely translation: "People expect their cards to work, we deal with serious Won every minute, this z stuff is the best damn tech for the mission, and IBM wanted our business." BC Card, founded in 1982, has never had a mainframe before.
