The South Korean government is switching from Windows to an operating system based on Linux according to The South Korean ministry of Security. The government uses Windows 7 and the free support for this will stop next year.
The Ministry of Security will first test the PCs in a closed environment to see if they are safe for use with current ICT systems. The South Korean ministry mentions various alternatives for Windows, including Ubuntu.
The South Korean government wants to switch, because it has to replace the current operating systems because of the end of Windows 7 support next year. After that, support from Microsoft will cost much more.
The systems will be replaced in phases in order to continue to see whether all systems related to e-government and ICT in the South Korean government are working properly. The switch costs 780 billion Korean won, around $ 655 million.
