Horizontal and Vertical Clustering

There are two methods of clustering

• Horizontal Clustering
• Vertical Clustering

Horizontal Clustering:

Horizontal scaling involves running multiple Java application servers (JVM) on two or more separate physical hardware’s (machines). When you scale horizontally, you add additional hardware that hosts additional JVM to the cluster.

Vertical Clustering:

Vertical scaling involves multiple Java application servers (JVM) running on a single physical machine. When you scale vertically, you join additional JVM to the cluster by adding to the same physical machine, which is limited by the limitation of the same physical machine.
