Answer 1

The in-process Servlet containers are the containers which work inside the JVM of Web server, these provides good performance but poor in scalibility.

The out-of-process containers are the containers which work in the JVM outside the web server. poor in performance but better in scalibility In the case of out-of-process containers, web server and container talks with each other by using the some standard mechanism like IPC.

In addition to these types of containers, there is 3rd type which is stand-alone servlet containers. These are an integral part of the web server.
