Observation two

Scale “great and terrible”Systems failSystems change

Netflix and Chaos Monkey

“…One of the first systems our engineers…is called the Chaos Monkey. The Chaos Monkey’s job is to randomly kill instances and services within our architecture. If we aren’t constantly testing our ability to succeed despite failure, then it isn’t likely to work when it matters most – in the event of an unexpected outage…”

Failure – embrace it

“…change our minds to assume that every machine can fail at any time without notice and that that’s OK and expected, not an OMG moment where you freak out trying to bring it back…”

Friend: Mir Rosenberg

Change

Business requires changeInternet businesses require rapid changeChange is the root cause of most site-downsHmmm…

Change – embrace it

“…“In the last week there were 67 deploys of 496 changes by 18 people” – Flickr Dev Blog.…”

Microsoft “service”...Customer agent tried to fix something, but made it worse

PM (program manager) fixed automation to be idempotent
