Red Hat Linux v9 New Features Course

For system administrators with experience in Red Hat, Centos, and Fedora Linux.

This training is oriented to Linux system administrators based on Red Hat and its sister distributions such as CentOS and Fedora. During it, you’ll get your own Red Hat® 9 deployment up and running in a simple, hands-on workshop created from our experience as Cloud, Linux, and DevOps trainers and consultants.
Red Hat Enterprise Linux v9 introduces significant new features in several key areas, such as virtualization, container management and network configuration, adding to the enhancements in version 8.
In addition, RHEL 9 continues to build on the foundation laid by the systemd-based version 7, which revolutionized the administration of this operating system.
With Red Hat 9, these tools and technologies have been enhanced and optimized, offering administrators greater flexibility, security and efficiency in managing complex enterprise environments.

Audience

Systems administrators, architects and pre-sale engineers with extensive UNIX or Linux experience. For new administrators we recommend taking one of our intensive GNU/Linux management courses first.
