Spacewalk is open source systems management software developed by Red Hat. It is the upstream version of the Red Hat Satellite, which was open sourced in 2008. Spacewalk includes the web interface and back-end, as well as Red Hat Proxy Server and associated client software of Satellite and makes them available to users and developers under a free and open source software (FOSS) license. The relationship between Spacewalk and Satellite is analogous to the relationship between Fedora and Red Hat Enterprise Linux. Whereas Satellite manages only RHEL and Solaris systems, Spacewalk manages Fedora, CentOS, SUSE and Debian systems.[1]

It is free software licensed under the terms of the GNU General Public License version 2. While formerly requiring the commercial Oracle Database as a backend, version 1.7 (released in March 2012) added support for PostgreSQL.[2]

Satellite 5.3 is the first version to be based on upstream Spacewalk code.[3]

In March 2011 Novell released SUSE Manager 1.2, which is based on Spacewalk 1.2 and supports managing both SUSE Linux Enterprise and Red Hat Enterprise Linux.[4]


Spacewalk and Red Hat Satellite are in long-term support mode for Red Hat, as they were designed monolithic to duplicate the RHN experience that customers saw in 2001 on Red Hat website to be internally deployed into a company or organization intranet. Therefore, the design criteria were web centric before the cloud and system management tooling such as Chef and Puppet & cfengine or other 3rd party tooling openstack . Red Hat has embraced current Open Source Components, like Puppet and Foreman to be the Underlying of the Satellite 6 Release, which currently is running in a Managed Design Program, slated for release in 2014.
