With Red Hat Satellite, you can deploy, configure, and maintain your systems across physical, virtual, and cloud environments. Red Hat Satellite provides provisioning, remote management and monitoring of multiple Red Hat Enterprise Linux deployments with a single, centralized tool.
- Red Hat Satellite Server synchronizes content from the Red Hat Customer Portal and other sources. It provides detailed lifecycle management, user and group role-based access control, integrated subscription management, and advanced GUI, CLI, and API access.
- Red Hat Satellite Capsule Server mirrors content from the Red Hat Satellite Server and distributes it to different geographical locations. Host systems pull content and configurations from the Capsule Server in their location instead of the central Satellite Server. The Capsule Server also provides localized services such as Puppet server, DHCP, DNS, or TFTP, assisting in scaling Red Hat Satellite as the number of managed systems in your environment grows.
