In this chapter, we saw the main configuration of the cluster present in WildFly, and we tested the web sessions in a very simple mode. We are now ready to create our nodes and test our distributed applications. Many applications need many nodes, so they become expensive. For testing, we can use OpenShift, which offers free nodes to install and execute our applications.

In subsequent chapters, we will show you how to work with WildFly in a cloud environment OpenShift and deep configurations starting with WildFly until the Infinispan deployment descriptors.
