names, IP Addresses, and some administration capabilities. For the users, it is almost as if they
have their own web server, without the hardware and basic server maintenance. These virtual
servers do not span application server instances. For more information about virtual servers,
see
Chapter 13, “Configuring the HTTP Service.”
In operational deployments, for many purposes you can use virtual servers instead of multiple
application server instances. However, if virtual servers do not meet your needs, you can also
use multiple application server instances. On stopping, application server instance stops
accepting new connections, then waits for all outstanding connections to complete. If your
machine crashes or is taken offline, the server quits and any requests it was servicing may be
lost.
