Overview
“Linux High Availability with Pacemaker” is designed for roles such as System administrators and Linux beginners and DevOps and platform engineers. In 6 hours you work your way through Corosync and quorum, Resources and constraints and STONITH and fencing in a structured way – with plenty of practice and time for your questions.
Linux and Unix form the backbone of servers, cloud platforms, databases and network services. Anyone running these systems needs confident command-line skills, a clear understanding of file systems, services and networking, and the ability to narrow down problems quickly. Our Linux High Availability with Pacemaker courses are aimed at beginners, administrators and operations teams who want to consolidate or deliberately extend their knowledge. We work exclusively on real systems in a provided lab environment: you type, fail, analyze and solve. The course runs online or on site, lasts one day and is offered at a fixed price per participant.
The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.
