- Oracle DB (if run on the same machine)
- Apache server running mod_python and mod_perl webapps
- tomcat server running the java webapp
- a java search server indexing the db content for searching
- another java service called taskomatic running a number of long running
  tasks.

There are a number of things that are going on while Spacewalk
is running it is NOT just a website, corporate or not.
