RedHat France has just finished the migration of 2500 servers of the ministry of the French national education to Linux OS , hosted in 30 local administration authorities. They used to work with several proprietary systems supplied by Bull ( Gcos 7, DSP 7 and AIX).
Michel Affre, the responsible of information systems for academic institutes explained this migration for better organization of these systems and their costs by distinguishing between the hardware and the software suppliers.
By including 2500 new machines, the ministry of education will be hosting 3000 servers running with Linux OS. That means 100% of their operating systems are free software !
These servers are intended to do financial management, exams administration, staff and students management and acts of daily administrative acts.
