Applications of cluster analysis in data mining: In many applications, clustering analysis is widely used, such as data analysis, market research, pattern recognition, and image processing. It assists marketers to find different groups in their client base and based on the purchasing patterns. They can characterize their customer groups. Clustering means you run a program on several machines (nodes). One reason why you want to do this is: Load balancing. If you have too much load/ work to do for a single machine you can use a cluster of machines instead. A load balancer then can distribute the load over the nodes in the cluster.
