Using Cloud and Continuous Delivery to
Speed Up Innovation
Adrian Cockcroft @adrianco
Cloud Expo Europe – 26th February 2014

What I learned from my time at Netflix
● Speed
wins in the marketplace
● Remove
● High
trust, low process
● Freedom
● Don’t
friction from product development
and responsibility culture
do your own undifferentiated heavy lifting
● Simple
patterns automated by tooling

Typical reactions to my Netflix talks…
“You guys are
crazy! Can’t
believe it”
“What Netflix is
doing won’t work”
– 2010
It only works
for ‘Unicorns’
like Netflix”
– 2009
– 2011
“We’d like to do
that but can’t”
– 2012
“We’re on our way using
Netflix OSS code”
– 2013
