OpenShift<\/strong> = Red Hat\u2019s enterprise platform built on top of Kubernetes<\/strong> + many important extras<\/strong>:<\/p>\n\n\n\n
\u2705 Security features
\u2705 Developer-friendly tools
\u2705 Built-in monitoring\/logging
\u2705 GUI Console

\n\n\n\n\ud83e\udde9 Visual Picture<\/h1>\n\n\n
Kubernetes = The Engine\n +\n OpenShift = \n - Security System\n - Navigation System (GUI)\n - Auto Upgraders\n - Integrated Pipelines\n - Registry & Operators\n - Monitoring\/Logging\n - Compliance Ready\n - Multi-cloud Ready\n<\/code><\/span><\/pre>\n\n\n
\n\n\n\n\ud83c\udfaf Final Key Points:<\/h1>\n\n\n\n
\u2705 Safer, easier, and faster to deploy real<\/strong> apps (not just test apps)
\u2705 Red Hat maintains + supports OpenShift long term
\u2705 Highly recommended for production use in real companies<\/p>\n\n\n\n
