Application Server
Excenit RSS is a web application, which means it primarily executes in a browser. To render the content it uses the popular open-source Tomcat Application Server 9+. It is possible to use other application servers.
Typically, the Excenit support team would install and configure the Tomcat. However, having basic understanding of the application server processes would be helpful in troubleshooting common concerns such as stopping and restarting the application.
