Abstract: Deploying Jboss/jBPM based portals for small local authorities has resource and security constraints.
Our objective is to deploy as much as possible portals on the same hardware, however, due to data protection legislation and to enhance security, these portals ought to be isolated.
Our portals are based on the same technology, with multiple modules as WAR from different providers. The portals has been developed with JSP and POJO over Jboss/jBPM. MySQL was selected as database, and Fedora Core as OS.
We performed stress-tests, with 3000 complete processes petitions on 9 portals. The test include virtualization scenarios with XEN and Vmware server, chroot jails, multiple JBoss/jBPM instances on the same machine, and one JBoss/jBPM instance with multiple portals.
They indicate that the big constraint of these configurations is memory usage, specially when using virtualization. Our best option in this moment is multiple JBoss/jBPM instances on the same machine, however there is still a big memory and cpu waste. We know that the optimal is one JBoss with one jBPM, but this can’t be done due to isolation problems.
As a conclusion, we propose to implement a virtual jBPM enviroment, where multiple applications could run isolated.
