What is WebSphere Application Server clustering?
A cluster is a set of application servers that you manage together as a way to balance workload. You must create two server clusters in your WebSphere Application Server environment. One cluster hosts the IBM® Security Identity Manager application. The other cluster is used as a messaging service.
What are different types of WebSphere clustering?
You can use vertical clustering to create multiple JVM processes that, together, can use all of the available processing power. Hybrid clustering is a combination of horizontal and vertical clustering. In this configuration, disparate hardware configurations are members of the same cluster.
What is application server clustering?
Application clustering (sometimes called software clustering) is a method of turning multiple computer servers into a cluster (a group of servers that acts like a single system). Clustering software is installed in each of the servers in the group.
What is dynamic cluster in WebSphere Application Server?
What Is Dynamic Cluster in WebSphere?

What is horizontal cluster and vertical cluster?
Horizontal clustering is when we are configuring the domain across multiple machines, with each machine having atleast one Managed Server. Vertical Clustering is when we are configuring the domain in the same machine which is having multiple Managed Servers.
What is application level clustering?
What is high availability in WebSphere application server?
What is dynamic clustering?
A dynamic cluster is a server cluster that uses weights and workload management to balance the workloads of its cluster members dynamically, based on performance information that is collected from the cluster members. Dynamic clusters enable application server virtualization.
