Spacewalk is an open source (GPLv2) Linux systems management solution. It is the upstream community project for Red Hat Satellite 5. Its capabilities include:
Red Hat Network (RHN Classic) first started in 2001 as a hosted service. RHN later spawned a stand-alone product called Red Hat Satellite. Spacewalk as a project officially became an open source, community driven project in June 2008, and it is the upstream for the Red Hat Satellite 5 & Satellite Proxy products.
Red Hat's continued commitment to open source technology and the open source development model drove the release of Spacewalk in 2008. By releasing the Satellite code base, Red Hat enhanced its ability to incorporate new open source management projects into the future roadmap for its products and solutions.
The Spacewalk project and the Red Hat Satellite product fully support and believe that community participation is a critical success factor for any open source initiative.
Spacewalk is a project where you can make use of the latest free & open source management technologies. Changes will occur frequently in the Spacewalk project to fulfill this mission. However, if your needs require a level of stability and support, you may decide that a Red Hat Satellite subscription is right for you. Please refer to the table below for some direct comparisons:
|Primary Benefits||Stable and supported.||The latest technology released early and often.|
|Feature selection and Integration||Red Hat||Red Hat and developer community|
|Development Model||Open source||Open source|
|Architectures||x86_64 & s390x||x86_64|
|Managed Systems||Red Hat Enterprise Linux||Fedora, CentOS, SLE and Debian|
|Red Hat Support Options||Many, including 24x7 premium with unlimited incidents||None (community supported)|
|Content Stream||Direct via Red Hat Customer Portal||Manual Import|
|Maintenance and updates||Available via Red Hat Customer Portal||Community-driven|
|Where to Buy||Contact Red Hat Sales, and partners||Free download|
|Price||Annual subscription, multiple offerings||Free download|
The true value of a Red Hat Satellite 5 subscription is similar to the value of any Red Hat subscription, including:
Spacewalk is supported within an open community via IRC, mailing lists and bug reports, similar to the Fedora community. There is no pay-for support for Spacewalk, nor is it supported by the Red Hat Global Support Services.
No, Spacewalk no longer has an entitlement model. In order to be able to synchronize Red Hat software content directly from cdn.redhat.com, you need the Red Hat Satellite 5 product with an active Satellite certificate.
The Red Hat Satellite 5 product is in maintenance mode, and is no longer accepting new features. Only security and stability fixes will be applied from Spacewalk to Satellite 5. Fixes are prioritized and released to Satellite 5 as asynchronous errata, on as as-needed basis.
The Red Hat Satellite server, including the web interface and back-end, as well as Red Hat Satellite Proxy Server and all clients that connect to Satellite are now open source. Satellite can now run on its embedded PostgreSQL (default) database, or optionally with an external Oracle or Postgresql database. Spacewalk can also run on Oracle or PostgreSQL. Both Satellite and Spacewalk are completely open source.
Red Hat Satellite 6 is a re-engineering of the Red Hat Satellite product. Spacewalk (and its downstream product, Red Hat Satellite 5) is a systems-management tool, and Satellite 6 is designed to accomplish the same set of goals. However, Satellite 6 has been built from the ground-up on different and more modern technologies. Spacewalk is not the upstream for Satellite 6, and never will be.Instead Satellite 6 is a federation of several upstream open source projects, including Katello, Foreman, Pulp, and Candlepin.
The Red Hat Satellite and Proxy Server Lifecycle shows that Satellite 5 will continue to be supported by Red Hat until May 31, 2020. Spacewalk remains the upstream for Satellite 5, and Red Hat will continue its "upstream first" philosophy on updates for the benefit of the Spacewalk community. Red Hat will continue to manage and maintain the Spacewalk project, infrastructure, and builders. Releases will be created as deemed appropriate. However, Red Hat's code contributions will decrease over time, as the focus shifts to maintenance and stabilization of the current set of features.
