I'm really interested in the comparison of using a FBSD jail rather than VMWare in the context of virtualization. At my business, we heavily use VMWare - you might say we consider ourselves a VMWare "shop". 99% of our servers are virtualized. I've heard that it's possible to run hundreds, if not thousands, of services in FBSD jails on a given host server because of the sharing of resources that all of your jails take advantage of. If I understand that correctly, that's one of the HUGE advantages of running services in jails as opposed to creating VM after VM after VM - each VM eats up disk space on the SAN as well as memory resources, etc. Additionally, the jailed service is far better from a security perspective? Having said all of that, I'm curious to hear from some of you who may be doing just this - are you running a FBSD server with some of your mission critical services (Apache, Bind, DHCP, etc., etc.) within jails and how do you like it versus running hundreds of VMs and VMWare? What type of services CAN be run from within a jail? Thank you, Ed
