Companies such as Anglo-Dutch oil company Royal Dutch/Shell, Venezuelan bank Banco Mercantile and Sweden's Telia have replaced many of their servers with machines running on Linux.
Sonera said they have replaced 60 different high end servers running Windows NT and various flavors of Unix with a single computer containing 500 virtual servers running Linux software installed by Red Hat and SuSE. This new computer from IBM requires 75% less space, requires less energy and allows Sonera to integrate all its services on one system and tweak the software if it wants to add new services.
Because the virtual Linux servers are all part of one computer, they can share their computing capacity. The computer also can add new virtual servers on the fly, Normally, you need separate servers for separate services, said Sonera's Technical Director Pasi Sutinen Sonera is expanding its basic Internet access offererings by adding services such as Internet telephony, data security, network services and other applications that the company declined to specify. Linux makes this much easier to manage cause its all on one box, better yet though is the fact that you can add new servers as needed in a short time frame and not have to worry about licensing issues which plague other OS's. This allows us to be more dynamic about our growth expectations. If you wish to read up more on this, click here
