FreeBSD jails evolution
I’ve just read a very intriguing post by Ivan Voras titled “The night of 1000 jails” and I wish only report some reflections I’ve posted as comment to his article.
FreeBSD Jails are perhaps the best responses to today’s optimization needs in the whole IT world, and I’m really committed to make the most IT pros aware of this big opportunity to cut costs and increase efficiency, and reducing complexity at the same time.
I think that both network stack virtualization and ZFS support are essentials pieces which complete the technical picture, but we need a comprehensive management tool to convince IT staffs to adopt this great solution. I feel the best candidate to become such a definitive tool for managing jails in production business environments is the ezjail framework (http://erdgeist.org/arts/software/ezjail/), but it should leverage the latest features (FIBs, vimage, ZFS, etc.) as soon as they are available for each -RELEASE.
With such tools in the hands, I’ll definitely be able to make a bunch of sysadmins switch from the most famous hardware-virtualization tools to FreeBSD Jails, today!
