Working on getting ready for the “Everything is a little bit broken; or, The illusion of control” talk by @wiredferret.

We are practicing some resilient behavior trying to get a presentation up without the right A/V cables... anyone have a Lightning-to-HDMI?

And we are good!!!

Did you know that Airplanes have an error budget? There’s a level of acceptable “failure” or lack of maintenance allowed prior to a plane being grounded - even if it’s just the overhead storage latch failing.

There’s a definite theme at #VelocityConf this year with abstraction. Both it’s benefits and it’s complexities.

We are moving away from the “cow/cattle” analogy and we are now at a point of container management where we are closer to the scale of “bacterial colonies” - @wiredferret

Conceptual compression - we are making bets on the fact that we no longer need to care about lower levels of our stack, we trust that they will function... until they don’t - see Heartbleed

Technical debt is inevitable, it’s how we derive business value. It’s a known trade off.

Dark debt is the debt you don’t realize you’re incurring... until it’s time to pay it off - normally quite unexpectedly and abruptly

Control is an illusion. We are generally operating under the assumption of control vs actually having it.

Failure is inevitable! This is true in our systems and the systems we depend on and they systems those systems depend on.

#VelocityConf

How do we deal with the fact that failures are going to happen?

Adopt practices that enable the mitigation of failure (circuit breakers, isolation, rapid rollback) and understand your failure tolerance.

Also, “disasters take teamwork!” - @wiredferret
