Vagrant, the open-source and cross-platform virtual development environment creation software, has always been an important part of the CentOS GNU/Linux distribution, which is based on the freely distributed sources of the commercial Red Hat Enterprise Linux (RHEL) operating system and the preferred OS for servers. The Vagrant Box editions of CentOS Linux 7 and CentOS Linux 6 consist of a minimal set of packages and are designed for system administrators who want to build a barebone CentOS server on virtual environments. The Vagrant Boxes can be easily compared with the CentOS Cloud and CentOS Minmal flavors.
