You have probably heard about ZFS. But perhaps you are still wondering what all the fuss is about, what it is exactly and how to use it. I’ve been using it for the past 3 years, so I hope I can help you understand how you can benefit from it. In a nutshell, ZFS is a combined filesystem and logical volume manager.

ZFS was created at Sun Microsystems and open-sourced as part of OpenSolaris.

The software ages and the technical debt runs up. According to Deloitte, the typical application comes with $3.61 worth of technical debt per line of code. That debt accounts for every fast-but-imperfect patch or app architecture that ages and also makes innovations hard to apply.

Legacy code: a time bomb for your business?
