Early unix mainframe computing brought elegant process and resource
sharing systems which helped get more application use out of expensive
hardware. These concerns have been largely been pushed aside in
computing with the rise of desktop PCs, and large farms of
ever-shrinking pizza boxes in the data center.
Today, as more punch gets packed into 1u than ever, server resources
can be further consolidated and abstracted to securely separate complex
and sophisticated services in the same hardware server, by running
secure virtual UNIX machines. FreeBSD Jails are a time-tested, secure,
reliable UNIX virtual machine with endless uses.
Who wants jails?
- System Administrators who need to securely separate small yet
- Software Developers who always need more dev machines.
- System Architects who need affordable high-availability systems.
- Educators who could use virtual machines to provide clean unix server
systems for student use.
What I think people would like me to talk about:
- How Jails Work, the technical nitty-gritty
- How to setup jails, the practical how-to, cooking show style...
- When NOT to use jails
- jail(8) security vulnerabilities
- Jails vs. Linux UML, technical and philosophical differences
- Tools and management practices
