Another colleague blog post on the LXD work going on in Juju. This feeds a thought I had myself. What if I had a beefy machine and ran LXD on it. Could I have Juju, on my laptop, communicate and control that empty husk of hardware to build infrastructure. In my case I was thinking of testing and QA at scale. +Wayne Witzel gave it a shot and found that it could work...with some more work.

Network partitions happen, your distributed system needs to be designed to handle them. One of the reasons they're often not tested is the difficulty in setting up failure scenarios.
I'd like to show jupsen (https://github.com/mattyw/jupsen). Jupsen is a juju plugin that allows you to model network partitions in a simple way, so you can easily test how your app handles them.
I will start by giving a brief tour of the commands available. I will then show an app writing to a mongodb replica set during a network partition. I will create a partition that causes lost writes, and demonstrate how you can guard against them.
