Always on the leading edge of technology, EFiS was one of the first organizations to use Linux for mission-critical applications in 2004. At the time, the company converted its COBOL-based banking application to run on Linux on System z, as well as IBM AIX*, HP-UNIX* and Sun Solaris. More recently, EFiS migrated more of its application base to Linux. In 2009, for example, it migrated many AIX, HP and Sun application instances to an IBM System z9* Business Class running Linux. This allowed EFiS to streamline its IT environment through consolidation and take further advantage of the power of Novell SUSE Linux Enterprise Server (SLES) running on System z solutions.
