Satellite (software)

In computing, Red Hat Satellite is a systems-management product by the company Red Hat which allows system administrators to deploy and manage Red Hat Enterprise Linux (RHEL) hosts.

A Satellite server registers with Red Hat Subscription Management, mirrors all relevant software like security errata and bug fixes, and provides this together with locally added software and configuration to the attached servers.

The managed hosts register against the local Satellite server and access the provided resources like software packages, patches, configuration, etc. while they also provide information about the current health state of the server to the Satellite
