Spacewalk is an open-source systems management application developed by Red Hat. It was formerly 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 was 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.
Spacewalk consists of 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.
Satellite 5.3 was the first version to be based on upstream Spacewalk code.
As of 2015[update] Spacewalk and Red Hat Satellite 5 are in long-term support mode for Red Hat, as they were designed as monolithic tools that duplicated the Red Hat Network experience, but in an internal deployment. The design criteria were web-centric before the rise of cloud-computing platforms like OpenStack, and configuration management tools like Chef and Puppet. Red Hat chose open-source components (including Puppet and Foreman) as the basis of Satellite 6, which was released in September 2014.
