RHUI 4.0 offers faster installation and deployment, support for RHEL 9, and database and storage optimization. This release includes a wide range of features requested, many of which came directly from our partners, such as additional security features and documentation. With hundreds of cloud providers around the world leveraging RHUI to manage their multi-tenant service infrastructure, it is a key tool enabling service providers to deliver RHEL as a managed service. 

What is RHUI?

Red Hat Update Infrastructure (RHUI) is a content management platform for cloud service providers that offer RHEL on a multi-tenant infrastructure service. RHUI helps cloud service providers meet service level agreements (SLAs), improve system consistency, reduce errors and meet compliance standards by delivering content and updates to Red Hat Enterprise Linux (RHEL) instances. 

RHUI has a highly scalable, redundant framework that allows cloud providers to locally mirror Red Hat-hosted repository content, create custom repositories with their own content, and make those repositories available to a large group of end users through a load-balanced content delivery system.

Before you install:

  1. Must be enrolled in the CCSP program.
  2. Requires RHEL 8 or greater to install RHUI 4.0 infrastructure components. 
  3. Any CCSP partner who offers RHEL on a multi-tenant service infrastructure should use RHUI for content management.
