True. I prefer the multiserver install because I have a Java background and I like the extra level of control and flexibility. > The JRE (or SDK) runs on the OS.

The VM is the Virtual Machine that interprets the Java bytecode and (on some JVMs like Sun's HotSpot system) compiles bytecode to machine code for extra performance. The JRE is the Java Runtime Environment which includes the JVM as well as all of the libraries needed to run (most) Java applications. This is also referred to as J2SE and, now, Java SE (Standard Edition) since we're a long way past Java 2. The JDK is the Java Development Kit and includes the compiler and some other stuff (as well as the JRE). Then there's J2EE which is now known as Java EE - Enterprise Edition. This includes all of the additional libraries and tools for writing Enterprise Java Beans and all of the "optional" stuff in the EE spec above and beyond the SE spec. > Then your app server runs on that.

Yes, a Java EE app server runs on top of the JRE and provides all of the libraries etc that are part of EE (above and beyond SE). But Tomcat - a Servlet container - also runs on top of the JRE. Think of a Servlet container as a (fairly small) subset of a Java EE app server. > Then your CF instance(s) are deployed to the app server (possibly as an EAR > or a WAR). Right, CF can run on "any" Servlet container such as Tomcat or "any" Java EE app server. A WAR can be deployed on a Servlet container. An EAR requires a Java EE server.
