Architecture
Red Hat Satellite Server
The Red Hat Satellite Server enables planning and management of the content life cycle and the configuration of Capsule Servers and hosts through GUI, CLI (Hammer), or API (RESTful API).Capsule Servers
Capsule Servers mirror content from the Satellite Server to establish content sources in different geographical locations, they are analogous to the Red Hat Satellite 5 Proxy Server.Managed Client Systems
As well as Supported Managed Hosts Red Hat Satellite 6 also has some deployment and management capability on certain other hosts though Red Hat Support for these will be limited.Connection to Red Hat Customer Portal and External Content Sources
Satellite generally operates in "connected" mode, registering directly with the RHN and downloading relevant software into Satellite's software channels. The organisation's hosts then register against the local Satellite server, instead of directly against Red Hat Network. For secure deployments, Satellite can operate in a "Disconnected" mode, where updates are downloaded directly from Red Hat via an Internet connected machine and then uploaded into Satellite or a local offline RHN proxy. Both modes allow the organisation to control which versions of software it makes available for its hosts, as well as making additional software available within the local network.Red Hat Satellite 6 components
Provision
Satellite offers numerous methods for deploying hosts, including simple '' kickstart'', ''Manage
Satellite assists in remotely managing hosts in several areas: software, operational management, and configuration. The 3 main mechanisms for managing hosts are: * Software Channel * Configuration Channels * Activation KeysMonitor
Satellite can provide monitoring of software and systems via probes. These probes periodically explore the target host and send alerts if the probes do not get the correct replies, or if the replies fall outside of some specified range.History and Lifecycle
A primary purpose of earlier versions of Satellite was to allow organizations to utilize the benefits of Red Hat Network (RHN) without having to provide public Internet access to their servers or other client systems. Later version of the tool have developed increased functionality.Future of Red Hat Satellite 6
The Lifecycle of Red Hat Satellite 6 is recorded at the ''Red Hat Satellite and Proxy Server Life Cycle'' which is updated as required, with future events on a '' bona fide'' basis. When viewed in August 2019, Red Hat didn't indicate any date for end of support.Red Hat Satellite 5
For Red Hat Satellite version 5 the Satellite Application 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. In the Spacewalk FAQ issued in 2015 after the release of Red Hat Satellite 6: * Red Hat formally released Spacewalk as open source(GPLv2) in June 2008. * Red Hat would continue 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.Future of Red Hat Satellite 5
The Lifecycle of Red Hat Satellite 5 is recorded at the ''Red Hat Satellite and Proxy Server Life Cycle'' which is updated as required, with future events on a '' bona fide'' basis. When viewed in March 2017 Red Hat indicated: * Red Hat Satellite 5 is in the final ''Production 3'' phase. * The current releases, 5.6 and 5.7, would remain supported through January 2019. * A further minor release 5.8 will be the only release supported in a supplementary ''Extended Life Phase'' from February 2019 through to ''See also
