I have only used one version of Red Hat Enterprise Linux (RHEL) and have upgraded the operating system during its lifecycle. My experience upgrading it was very easy.

We manage our Red Hat Enterprise Linux (RHEL) systems for provisioning and patching using a combination of VMware vRealize for actual deployment, and then we use Ansible Automation for the day-two configuration and lifecycle. Once software deployments and configurations are all Ansible automation, it couldn't work any better for us.

The feature I appreciate the most about Red Hat Enterprise Linux (RHEL) is its long lifecycle. The long lifecycle helps my company by allowing us to plan ahead; we don't have to redeploy everything every five years or so. It helps to plan ahead.

RHEL consistently provides the stability, support, and knowledge base required to keep mission-critical systems running smoothly.
