Banks that already run Linux

The Industrial and Commercial Bank of China

The state-owned Industrial and Commercial Bank of China has shifted to Linux across all its 20,000 retail branches. The largest bank in China is committed to ‘an unrestricted user licence’ as part of a full-blown integration of Linux ‘throughout its entire banking operations network’. This is possibly one of the largest deployments of Linux, to date, in the Chinese financial sector. Essentially, Linux became “the basis for its Web server and a new terminal platform” at the bank.

Union Bank of California

In January 2007, the bank announced that it would standardise its IT infrastructure on Red Hat Enterprise Linux in order to lower costs.

Banco do Brasil

Banco do Brasil of Brazil, the biggest bank in that country, has moved nearly all desktops to Linux, except for a few that need to operate some specific hardware. The bank began migrating its servers to Linux in 2002. Branch servers and ATMs all run Linux. The distribution of choice is OpenSUSE 11.2.
