Red hat cluster
This presentation introduces clustering and RedHat clustering. It defines a cluster as two or more computers that work together to perform a task. It distinguishes between hardware and software clusters, with hardware clusters being more expensive. The major software cluster types are high availability, load balancing, and high performance. High availability clusters provide failover to prevent downtime. Load balancing clusters distribute work across servers. High performance clusters enhance application performance through parallel processing. The presentation recommends starting with RedHat clustering by downloading free documentation from the RedHat website.

- 12. 2-Load balancing - Frontend dispatching node - Pool of inexpensive back-end servers - Redirect transactions so NO one system is overloaded - Node failures in a load-balancing cluster are not visible from clients outside the cluster. Used For 1- Dispatching Web Traffic
