Running server operations using clusters of either physical or virtual computers is all about improving performance over and above what you could expect from a single, high-powered server. But "improving performance" can mean different things in different contexts. This course, Linux High Availability Cluster Management, will bring many aspects of performance improvement to light. You'll be introduced to the principles of Linux-based HA and cluster management and the key tools currently in use in real-world
environments - including Linux Virtual Server (LVS), HAProxy, Pacemaker, DRBD, OCFS2, and GFS2. You'll learn how to intelligently spread workloads among diverse geographic and demand environments (load balancing). You'll also discover how to provide backup servers that can be quickly brought into service in the event a working node fails (failover). Finally, you'll also learn about optimizing the way your data tier is deployed, or allowing for fault tolerance through loosely coupled architectures. By the end of this course, you will be able to improve and manage many aspects of the performance of your local or cloud Linux deployments, and they'll be more reliable for it.
