OCS is based on Project Kusu - an open source cluster management framework. The objectives of Kusu and OCS is to provide a repeatable, simple way to install and manage a cluster. This is where we are today. Kusu/OCS can easily install a cluster (beowulf style or flat network), install and upgrade applications either in rpms, tgz or Kusu native format known as Kits.

I call this generation 2 cluster. Generation 1 refers to the good old days when we install cluster by hand, where we create kickstart files and imaged out a cluster, hand-configure the .hosts files....

Generation 2 cluster toolkits provides a pre-package cluster deployment methodology. Within the toolkits, cluster deployment and management best practices have been codified. It makes cluster installation easy as "press next".. Okay by pressing several the next button on several screens. It can take between 45mins – 2 hours to build out a fairly large and complex cluster. This compares to the days we took previously with generational 1 clusters.

Moving forward are we going to see generation 3 cluster tools? Well....
