No, RHUI cannot be used for on-premises RHEL servers, even if they are connected via Azure Arc. RHUI is exclusively for Red Hat Enterprise Linux (RHEL) Pay-As-You-Go (PAYG) virtual machines running within Azure and is not accessible or licensed for on-premises or non-Azure environments.
Azure Arc facilitates the management and governance of on-premises servers, but it does not extend access to Azure-specific services like RHUI for these servers. On-premises servers will need to use traditional methods like Red Hat Subscription Management (RHSM) or other patch management solutions to obtain updates.
