@damovisa | #ndclondon

@damovisa | #ndclondon Humans is fallible

@damovisa | #ndclondon $440 million loss in 45min

@damovisa | #ndclondon We need more governance!

@damovisa | #ndclondon The Bureaucratic Deployment Cycle

@damovisa | #ndclondon The Bureaucratic Deployment Cycle Our deployments are
so far apart Because we have to test so many changes Because our deployments are so far apart

@damovisa | #ndclondon Slowing down can make things worse

@damovisa | #ndclondon Automation

@damovisa | #ndclondon Scripts are repeatable and trustworthy*

@damovisa | #ndclondon Automation != Good Process

@damovisa | #ndclondon Summary Get it in production Bureaucracy only
gives the illusion of safety Automate the whole process Fail happily in pre-production @damovisa | #ndclondon
