Mainframe technologies encompass the hardware, operating systems, and software—such as IBM z/OS, COBOL, DB2, and CICS—that power large-scale enterprise computing systems. IT professionals who specialize in this area maintain and modernize legacy systems that run critical operations for banks, insurers, and government agencies. Demand for mainframe skills persists because so much of the world's core transactional data still runs on these systems.
