Red Hat Update Infrastructure 4


Red Hat® Update Infrastructure (RHUI) offers a highly scalable solution to manage yum repository content for Red Hat Enterprise Linux® cloud instances.

Red Hat Update Infrastructure FEATURES

Manage Content with Red Hat Update Infrastructure.

This highly scalable solution helps you manage yum repository content for Red Hat Enterprise Linux cloud instances, hosted by Red Hat Certified Cloud Providers. RHUI allows cloud providers to:

  • Mirror Red Hat-hosted repository content locally
  • Create custom repositories with their own content
  • Make those repositories available to a large group of end users via a load-balanced content delivery system
  • Deliver RHEL 9 content. This feature is only available on RHUI 4.


Seamless upgrade process

Install RHUI 4 alongside an earlier version and then migrate your Red Hat repositories from that version to RHUI 4.  After RHUI regenerates entitlement certificates and updates client configuration packages, the clients start to smoothly pull content from the new RHUI 4 servers.

Faster access to content

The architecture supports a shared storage volume that makes content quickly available to clients. The Red Hat Update Appliance (RHUA) and the content delivery server (CDS) share the same storage location, and synchronization times between the RHUA and the CDS are now significantly shorter.

Improved installation process

You can configure all nodes in a single step, and the installer can create the necessary certificates.

Faster synchronization of repositories

The repository data is mirrored from the source rather than being generated locally. This allows RHUI to synchronize the repositories significantly faster.
