美国邮政总局迁移到GNU/Linux

2009年07月15日13:41
根据/.的报道, 美国邮政总局(U.S. Postal Service, USPS)把原来用Cobol写的包裹跟踪系统迁移到了在 HP机器上运行的GNU/Linux。 系统有 1,300个服务器,每天处理 4 千万个交易,而且开销比原来基于Solaris的系统少了。整个迁移用了一年。USPS没有说迁移到底能节省多少,只是说“相当大”(significant)。

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.

The migration is a part of a larger plan to standardize on open source software to lower operating costs and increase the number of transactions the system can handle. The USPS currently manages over 40 million transactions every day, from tracking priority mail to shipping packages for customers at local post offices.

Though the USPS won't discuss exact figures on how the cost savings of moving from a Sun Solaris environment to Hewlett-Packard, it's clearly substantial. Postal Service representative John Byrne told Government Computer News, “We’re achieving significant savings moving from the Sun to the HP environment — obviously not as materially as the IBM proprietary environment to Linux because the mainframe has had the higher cost to begin with and farther to fall.”

In today's sagging economy and economic downturn, its good to see the U.S. Government tightening its belt and cutting costs by using open source software to help curb spending. Although there are opposing viewpoints on the use of open source in government, FOSS is making significant headway and may be on the road to winning the race.
美国邮政总局日前将他们的包裹跟踪系统的运行环境更换到Linux平台。以前的这个跟踪系统是由Cobol语言编写的,目前已经为Linux平台做过相关转换,且可以在Linux平台良好运行,这可比将以前的系统重写一遍要来的便宜。

包裹跟踪系统运行平台的迁移,是美国邮政总局采用开源软件降低运行成本、提高系统交易处理能力计划的一部分。目前,USPS每天处理大约四千万份交易,为美国邮局系统提供从挂号信到邮政包裹的跟踪服务。

尽管USPS相关负责人并没有透露详细的数字,但是显而易见,从Solaris的软硬件转移到HP的硬件和Linux操作系统,肯定省下了一大笔钱。邮政系统的代表John Byrne告诉记者,虽然省下很多,但是不像从IBM的专有环境迁移过来,因为IBM的专有硬件设备太贵,所以省下的并不是大家想像的那么多。

在目前的经济不景气的大潮下,我们很高兴看到USPS能够通过采用开源软件的方式来度过时艰。虽然现在在美国政府内部还是存在着对开源软件的反对意见,FOSS还是在埋头奋进,或许我们就在成功的路上。
