On April 7 , 2009 , IBM celebrated the mainframe’s 45th year . Drawing on its roots in punch -card tabulators , the machine has come a long way to become many customers’ preferred e -business solution . Throughout its lifetime , IBM’s strategy adapted the machine to the changing market . During the late 1960s , the introduction of the System /360 provided customers with compatibility and scalability across various computer lines . Popularity of the system began to suffer during the client /server era of the 1990s but it quickly recovered as the z Series server line was developed to support e -business solutions . IBM’s strategy made the mainframe successful but continued improvements are still necessary to ensure its future success . |
