Hi Malmee,

Typically, different cells will win different instances of your 5 tomcat
servers, so you might have 5 different cells each running 1 tomcat server.
This makes your application more fault-tolerant, so that if one of the
cells die, you don't lose all 5 running tomcat servers, you lose maybe just
1.

You may not need to know the IP and port? If you do "cf push my_app -d
some.domain -n some-host" then (assuming you have DNS set up correctly),
Cloud Foundry will automatically load balance traffic to
http://some-host.some.domain across all 5 of your tomcat instances. The
IPs are generally dynamic, as your servers might be moved around the
various Cells over time (e.g. when Cells are rolled for regular
maintenance, your servers are rescheduled elsewhere). Also, when you
update the source for your application, not only will the servers
potentially start on totally different cells, but the internal identifiers
for your application will change, so whatever query you make for getting
your app's IPs and ports would have to change as well. Do you actually
need the IPs and ports?

Best,
Amit
