Uptime is critical, and this course will teach you the concepts and tools you need to maintain an extremely high level of availability for you Linux servers, even under heavy load.


This course is designed for IT managers, system administrators, DevOps, and technical personnel operating highly-available mission-critical Linux systems. Students should have a good working knowledge of fundamental operating system and hardware concepts and experience with network addressing and topologies. A basic foundation in mission critical deployments will also be beneficial.

Course Materials

Authorized printed training materials from The Linux Foundation. As part of your registration, a printed copy of the course manual will be course manual will be provided. If you are attending in person the material will be available onsite on the day the class begins.

Course Description

You can’t afford to have mission-critical systems go down, and this course will teach you how to ensure that your servers stand up under even the most intense pressure. Developed for some of the largest Linux deployments in the world, this course will teach you:

  • How to create and maintain systems that allow for highly-available applications.
  • The concepts and best practices used to meet security and high availability requirements using the latest hardware technologies.
  • You’ll also become familiar with tools that help you maintain and operate highly-available systems easily.

This course is designed to work with a wide range of Linux distributions, so you will be able to apply these concepts regardless of your distro.

Why train with The Linux Foundation

The Linux Foundation is the go-to source for training on virtually every aspect of Linux and many other open source technologies. Here are a few things that make The Linux Foundation the right choice for training:

  1. The Linux Foundation is the non-profit organization that hosts Linux and many other open source projects, employs Linux creator Linus Torvalds and hosts kernel.org (where all Linux kernel updates are released).
  2. Being so close to the kernel The Linux Foundation is constantly updating training to ensure that the most up-to-date information is being thought. Linux Foundation Training is unique in that all our training courses are designed to work on all major Linux distributions (including RedHat, Ubuntu and SUSE).
  3. The Linux Foundation does not sell any software or support services so there’s no hidden sales agenda in the training material. The only goal is to help students learn the material.
  4. When you train with The Linux Foundation, you’re learning from instructors who are comfortable across all major Linux distributions and can answer student questions regardless of the distribution you’re using for the class. You are truly learning from the experts.
