    Any web application to run needs a server for e.g. Tomcat, JBoss etc.. there are many application servers available in market. 

    Jetty is the server that comes prepackaged in AEM Jar, so when you run AEM using the JAR file, then the entire AEM is using Jetty to run and execute. Find more on Jetty here - http://www.eclipse.org/jetty/documentation/9.4.x/introduction.html

    AEM does offer some parameters that you can configure for Jetty. You can do it from felix console - http://localhost:4502/system/console/configMgr/org.apache.felix.http

    Also Jetty is not the only server compatible, but you can run AEM inside any application container, if you opt to do so, then you will need AEM WAR file and deploy AEM as standard web-app in those servers. Adobe does provide step-by-step guide on how you can install AEM in other application servers. Please refer it here - https://docs.adobe.com/docs/en/aem/6-2/deploy/application-server-install.html

    In the end the calls to AEM are received by the servlet-engine. Jetty is the implementation used.

    You can write your own servlets in AEM.

    AEM is an OSGi platform (a Java platform) - you can write OSGi services and servlets - for information - see: 

    https://en.wikipedia.org/wiki/OSGi#Services

    When writing Servlets for AEM - you typically write SLing Servlet and use APIs like: 

    https://sling.apache.org/documentation/the-sling-engine/servlets.html

    Hope this helps!
