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.

What’s new in RHUI 4.0?

  • Faster installation and deployment
    • Dramatic reduction in deployment time using Ansible playbooks 
    • Streamlined user experience with Ansible as the installer 
  • Support for RHEL 9 beta
    • RHUI 4.0 is required to deliver RHEL 9 content 
  • Simplified, in-place RHEL upgrades
    • Supports the use of  LEAPP, a CLI tool for in-place upgrades, for RHEL 6 to RHEL 7 or RHEL 7 to RHEL 8 upgrades.
    • Virtual machine hosts can upgrade without requiring guests to be redeployed
  • Database and storage optimization for faster synchronization of repositories 
    • Content repository database changed from MongoDB to PostgreSQL
    • Supports significantly faster synchronization of repositories with mirroring from the source rather than locally
    • Use Pulp repository management platform to retain specific number of package versions, reducing metadata storage 
  • Enhanced security
