I've thought about pitching it again (my application is
platform-agnostic, as long as there's a Tomcat installation it's
happy) but the company is just more comfortable with Linux. Our
developer makes a pitch every now and then for a switch to Linux as
well, but we just don't have the in-house knowledge to make it happen.
We're a small shop and already have too many people wearing too many
hats - makes the SOX auditors edgy as it is.

We're already running a bunch of virtualized servers - version 2 of my
app is running on 4 virtual servers, one for each environment (unit
test, acceptance test, etc.). And we're out the cost of one Windows
license per server, for this one application, which can run happily
under Linux (better, actually - I got snared by a Windows-only Ant
bug).

I actually did originally talk to my boss about running a
Subversion-only server, but the one Tomcat app we have today is going
to go down in usage over the next year, hopefully to 0 by the end of
2007 - so there wouldn't be too much resource conflict there (it
currently runs on a box which is also our database server, and we want
to make that box purely DB, so we'd move version 1 to this virtual
machine). He mentioned new Java web apps coming online and using that
app server but I have no idea what they would even be.

I'm still relatively new at this company so I can't rock the boat
*too* much yet.
