The new stuff

New complex problems (Cloud, Serverless)

Environments all the way down

We trust automation

Better tools (Docker, Puppet, Chef)

The App

The App is live!

We think people interested in hi-tech gadgets

will bring us the big bucks

We want to run a bucket load of experiments

We also have mobile versions, not just web

@gil_zilberfeld

The App

Design the pipeline from dev to production with

the goals:

Quick feedback

Do not interrupt production

Describe risks mitigations, capabilities, and

issues
