Summary

We have discussed vertical clustering using the multiple instances feature, horizontal clustering, and easy application management by using the farming support provided by Geronimo. We have also configured session replication by using WADI, and load balancing by using the Apache web server, mod_jk module, and AJP connectors. We have demonstrated the same by using the helloworld-cluster web application sample. In the next chapter, we will discuss the support provided by Geronimo for logging. You will learn to configure application logging using the various logging frameworks provided by Geronimo.
