I was browsing the Vatican Library website when I chanced upon this bit of interesting information. The Information Technology Center (C.E.D.) of the Vatican Library uses Red Hat. The site’s info page reveals that C.E.D.’s networks “are protected internally by two first-level firewalls in a Linux Red Hat environment”. But that’s not all. Of the 27 servers the Center uses, 19 are in a SUSE and Red Hat environment. The rest are running in a UNIX AIX environment and in a Microsoft environment (virtualized on Linux systems with VMWare).
A variant of the Red Hat distro is also employed in the Digital Photographic Laboratory of the 500 year-old Library. According to this page, the operating system used for the storage equipment in the Digital Photographic Laboratory is Centos.
More technical information here about the systems they use in the Bibliotheca Apostolica Vaticana.
Established by Pope Nicholas V in 1448, the Vatican Library is one of the oldest libraries in the world. It contains more than 75,000 manuscripts and over 1.1 million printed books from throughout history, which makes it one of the most important repositories of knowledge in the world. The Information Technology Center of the Vatican Library was set up as early as 1985.
I am overwhelmed to know that the Church’s most important library uses the most secure operating system in the planet.
