Cluster means different things to different people. In the context of this article, cluster is best defined as scale-out — scale-out clusters generally have a lot of the same type of components like Web farms, render farms, and high performance computing (HPC) systems. Administrators will tell you that with scale-out clusters any change, no matter how small, must be repeated up to hundreds of thousands of times; the laziest of admins have mastered techniques of scale-out management so that regardless of the number of nodes, the effort is the same. In this article, the authors peer into the minds of the laziest Linux® admins on Earth and divulge their secrets.
actually one of the better articles on this site in a long time. Mentions a few technologies that I am interested in and was not aware of. Not so much a “cool” release article as it is a helpful tools of the trade article. The title is not one I would expect from IBM.com, hence the lack of interest.
