Excerpt:
Mainframe computers are used extensively in the operations of the world’s largest companies. These
computers are the foundation of large-scale commercial computing and web services that are critical to
modern business. Industries that use mainframes include banking, finance, healthcare, insurance,
utilities, transportation and government.

The original mainframe computers were developed and introduced by IBM in the early 1960’s. The
technology industry and workforce grew from these early years. In the 21st century, the mainframe
remains the champion for raw processing power and volume of data input and output.

A career in mainframe programming and administration offers good compensation, job security and
unique satisfaction. The companies, organizations and government entities that use mainframe
computers need skilled professionals. This need translates into high demand for people with technical
skills. The trend is strong for recruiting and hiring in this area.

Additional trends are improving the outlook for employment in this field including the retirement of large
numbers of current workers, the lack of mainframe courses in university curriculums and the greater
attraction of other technology areas to younger generations of workers.

...Jobs in mainframe system programming entail the installation, customization and maintenance of
mainframe computers and operating systems. Key areas of responsibility are mainframe hardware and
software including processors, system software, data storage and input/output devices.

The central objectives of reliability, performance and security are achieved through the management of
hardware and software configurations. System programmers ensure high performance, continuous and
secure data processing. They balance system resources, tune system performance and monitor for
disruptions to operations.
