It can change to address brand-new difficulties. The client/server computing model, which relies on dispersed nodes of less powerful computers, first appeared in the early 1990s to compete with mainframe computers’ hegemony. Industry experts referred to the mainframe computer as a “dinosaur” and prophesied its quick demise. As a result, designers created new mainframe computers to satisfy demand, as they have always done when faced with shifting times and an expanding list of customer requirements. As the industry leader in mainframe computers, IBM® gave its then-current system the code name T-Rex as a nod to the critics of dinosaurs.
The mainframe computer is ready to ride the next wave of growth in the IT sector thanks to its enhanced features and new tiers of data processing capabilities, including Web-serving, autonomics, disaster recovery, and grid computing. Manufacturers of mainframes like IBM are once more reporting double-digit annual sales growth.
The evolution keeps going. Although the mainframe computer still plays a key function in the IT organization, it is now considered the main hub in the biggest distributed networks. Several networked mainframe computers acting as key hubs and routers make up a considerable portion of the Internet.
You might wonder whether the mainframe computer is a self-contained computing environment or a piece of the distributed computing puzzle as the mainframe computer’s image continues to change. The New Mainframe can be used as the primary server in a company’s distributed server farm or as a self-contained processing center, powerful enough to handle the largest and most diverse workloads in one secure “footprint,” according to the answer. In the client/server computing approach, the mainframe computer effectively serves as the sole server.
