A professional tech illustration for a blog post cover. In the center, place the Red Hat Enterprise Linux logo next to the Docker whale logo. Below them, show a disconnected network cable. The background subtly depicts a server rack in a data center, slightly out of focus. Use a clean, modern design with a color palette of red, blue, and white. Add a faint binary code overlay for a tech feel. Ensure high quality, sharp details, and a polished look suitable for a technical blog post.
