- Systems Inventory (Hardware and Software)
- System Software Installation and Updates
- Collation and Distribution of Custom Software Packages into Manageable Groups
- System provisioning (via Kickstart)
- Management and deployment of configuation files
- Provision of virtual Guests

Spacewalk Server: Server represents managing System
- It is possible to set up master and slave servers, and even a tree setup is possible 
- There are options for geographically remote remote proxy servers 
Spacewalk Client: A system managed by a Spacewalk server
- Compatible Client OS's are drawn from:
Spacewalk is controlled by the following Interfaces:
- web interface, Used for most interactions
- CLI (Command-line interface), Used for some specific operations
- XMLRPC API Interface, programmatic interface for specialist/development use
- Particular upstream and downstream versions may include integration to supported vendor subscription support network such as Red Hat Network(RHN) and ULN and SUSE Enterprise Linux Server Subscriptions
- While formerly requiring the commercial Oracle Database as a backend, version 1.7 (released in March 2012) added support for PostgreSQL.
Upstream and downstream versions
A number of downstream versions use upstream Spacewalk version as the basis of their System Provision, patch and errata management:
Support for particular client OS, server OS, system architecture, Backend Databases and subscription services varies between versions and releases.
History and development
For Red Hat Satellite version 5 the Satellite Function was implemented by a toolset named Project Spacewalk.
Red Hat announced in June 2008 Project Spacewalk was to be made open source under the GPLv2 License
Satellite 5.3 was the first version to be based on upstream Spacewalk code.
Stewardship and governance
In the Spacewalk FAQ  issued in 2015 after the release of Redhat Satellite 6 Red Hat.
- Red Hat formally released Spacewalk as open source(GPLv2) in June 2008
- Red Hat continues to sponsor and support Spacewalk as the upstream Red Hat Satellite 5. however that participation is anticipated to diminish as Red Hat Satellite 5 enters the final phases of its lifecycle. Spacewalk is not and can never be upstream for Red Hat Satellite 6 released in September 2014 due to it being a ground up rebuild with a different toolset.
- The Spacewalk project can continue to grow and flourish providing the community continue to find it a useful tool and a willing to support it.

Red Hat Satellite 5
Red Hat Satellite 5 is a licensed downstream adaption of Spacewalk with added functionality to manage Red Hat Enterprise Linux Subscriptions. In the active years of the Red Hat Satellite 5 lifecycle Spacewalk was simply known as the upstream project for Satellite. The relationship between Spacewalk and Red Hat Satellite 5 was analogous to the relationship between Fedora and Red Hat Enterprise Linux. With the emergence of Red Hat Satellite 6 with based on a fundamentally different toolset, end of lifecycle phase of Red Hat Satellite 5 and the emergence of downstream spacewalk based offerings from Oracle and SUSE newer versions of Spacewalk may not have this close relationship.
SUSE Manager Server
As of February 2017 the current version of SUSE Manager is SUSE Manager 3.
SUSE Manager 3 is based upon Spacewalk 2.4. SUSE Manager 3 extends Spacewalk and incorporates integrates other components. Subscription Management Capabilities for Red Hat Enterprise Linux and SUSE Linux Enterprise Server are supported.
