There are three types of Adobe Campaign modules:
Multi-instance modules: a single process is run for all instances. This applies to the following modules: web, syslogd, trackinglogd and watchdog (activities from the config-default.xml file).
Mono-instance modules: one process is run per instance. This applies to the following modules: mta, wfserver, inMail, sms and stat (activities from the config-.xml file).
Utility modules: these are modules that are run occasionally to perform occasional or recurrent operations (cleanup, config, downloading tracking logs, etc.).
