U.S. Postal Service Switches To Linux26 Jul 2009
The U.S. Postal Service (USPS) has switched 1,300 of the servers that manage its package tracking system to a Linux environment. The move has taken the better part of a year since all the original system code was written in Cobol and had to be converted for Linux -- a less expensive option than rewriting it altogether.
A transition from Sun Solaris to Linux on HP produced "significant" cost savings.
