|The world's most popular open source operating system. "More secure than its competitors"|
Linux is the world's most popular open source operating system. It is widely used where reliability or flexibility is an advantage, such as for server farms, custom hardware or embedded systems. It is not invulnerable, but "generally speaking, Linux is more secure than its competitors."
Many different distributions have evolved, which vary in target audience, capabilities and business model. Many are freely available.
Corporations were initially wary of the free status of Linux, but its perceived reliability countered that. In 2020 the South Korean government announced plans to switch all 3.3 million of its computers to Linux.
Developing Vaccine Passport
In December 2020, the Linux Foundation has partnered with IBM, the COVID-19 Credentials Initiative and the World Economic Forum's CommonPass, a digital “health passport,” in order to develop vaccine credential apps that will be applicable globally. If the initiative is successful, people will be required to pull up a vaccine certificate on their phone showing when and where they were vaccinated, along with which type of vaccine, in order to get on a plane or attend an indoor event, such as a concert, for starters.
