The Psychology of Chaos Engineering

let’s set some agreement

Chaos Engineering is the discipline of experimenting on a system in order to build confidence in the system’s capability to withstand turbulent conditions in production.

Netflix Technology Blog, 2011 By running Chaos Monkey in the middle of a business day, in a carefully monitored environment with engineers standing by to address any problems, we can still learn the lessons about the weaknesses of our system, and build automatic recovery mechanisms to deal with them. So next time an instance fails at 3 am on a Sunday, we won’t even notice.

perceptions

“isn’t all engineering chaotic?”

It’s not about breaking things

look, I know you know this

I’m gonna say it anyway

these are experiments

we know this, Matty

how we talk about things matters

people get nervous

“You want to do what in production??”

use your monitoring like it’s for real because it is

Something’s broken… …it’s your fault

but what about the people?

how does it make you feel to know Netflix practices chaos engineering?

what about your bank?

data, such as it is

management can get… …nervous

consider your words

it’s about the philosophy

safety first

• Know your conditions - when will you shut down the experiment? • This isn’t about causing stress on your people - be transparent • There are humans at the other end of those numbers
