This appendix proposes a few techniques for deploying mod_perl on ISP machines. Therefore, it's mostly relevant to ISP technical teams and ISP users who need to convince their providers to provide them with mod_perl services.
There are at least four different scenarios for deploying mod_perl-enabled Apache servers that ISPs may consider:
Users sharing a single web server
Users sharing a single machine
Giving each user a separate machine
Giving each user a virtual machine
This appendix covers each of those scenarios.
