We have talked on numerous occasions about projects in the scientific world that use GNU / Linux distributions to work, many of them are NASA projects, also CERN, etc. But our European space agency, the ESA It is also one of the organizations that uses Linux in several of its projects, among other distros they are using SUSE and also the Red Hat competition for other systems that they have implemented for their work.
For example, ESOC (ESA's European Space Operations Center has chosen SUSE Linux Enterprise Server as a base operating system to control the operations of the stations and the control of the ships that launch into space. ESOC makes up a wide network in different countries, including Australia, Belgium, France, Portugal, Spain and Sweden. A large infrastructure with powerful servers to manage this control data. But it is not the only project within ESA that works thanks to an operating system based on the Linux kernel.
They have also built a large private cloud as a platform for their developments and have done so using the RHEL distribution, that is, Red Hat Enterprise Linux. With this cloud they provide a cloud computing platform to implement various types of services and applications that they need. Due to the field in which they operate, they need a powerful, reliable, robust and flexible cloud, something that the set of systems provided by Red Hat allows ESA.
In short, there are still many people who consider that Linux is an operating system that is not worth it or those who think that open source or free software is little less than programs that certain amateurs make and that do not work well. And the truth is quite different, since we have very good software that has the support of these large organizations to certify its quality.
