Linux High Availability Clusters

Description:

IT architects taking this course will be able to plan high available server clusters and systems administrators will be able to create and operate clusters. This practical course explains how to achieve high availability with Linux-HA or pacemaker (3-days) and Linux Virtual Server (LVS) (2-days).

The basics of HA like syncing data between two nodes (DRBD), arbitrary fail-over conditions, operating and monitoring of clusters are covered. Additionally the following technologies are used in the class: heartbeat, OpenAIS, pacemaker, ldirectord, DRBD, cluster filesystems like OCFS2, and Linux Virtual Servers as a load balancer.
