DynaFabric is an SSH based command dispatching and systems management framework, designed for easy implementation on existing networks. It allows you to configure SSH key based authentication, and centrally dispatch commands, manage installed software, maintain services, and enforce policies across your systems.
DynaFabric is designed to be platform agnostic; support is being developed for FreeBSD, OpenBSD, NetBSD RHEL/CentOS, Ubuntu, Solaris 10, Solaris 11, and Illumos.
DynaFabric is a promising new configuration management system. Its like Ansible, but with the convenience of a dynamic database backend (in MongoDB!). I will be following the progress of its development very closely indeed.
