First keynote of the morning at #AgileDevOpsCon is @aglover explaining The Netflix Approach to Continuous Delivery.

The Netflix drive to #continuousdelivery was driven by developers, not operations.

They developed Spinnaker and then got other cloud providers to add to it to make it more pluggable. spinnaker.io

Netflix does red-black deployments, which most of us think of as blue-green deployments. Rolling deployments to make sure the very large server groups are coming up, canary analyses to make sure systems are working.

Netflix does 4000 deploys per day. Up from 2000 pre-Spinnaker. 4500 pipelines running per day.

Content is pre staged weeks ahead of time. Feature flags are used to enable content on the “release day”.

Continuous delivery is used to get constant feedback. Add new features and remove features that aren’t being used.

Resilience is built in. Failures will happen. Within 10 minutes, Netflix can reroute traffic to a different AWS region, and they practice this weekly.
@aglover #AgileDevOpsCon

Chaos experiments can be run directly from Spinnaker to do controlled experiments against your app in production. E.g., “can my app still serve traffic if the database goes down?”
@aglover #AgileDevOpsCon

Accept that failures will happen and then do blameless post-mortems to learn.
@aglover #AgileDevOpsCon

There are no edicts at Netflix. No one is required to use Spinnaker or the chaos tools. They use a paved road model to ease the way if you choose to do things as others have.

“We suck compared to how great we are going to be.” Always be improving.
@aglover #AgileDevOpsCon

Don’t overlook the value of learning as you build. You won’t get it right the first time so embrace experiments.

155 million members worldwide. 45 BILLION view hours per year. During peak viewing hours in the US, Netflix viewers consume about 35% of internet traffic.

People want to buy. They don’t want to be sold to.
Show them the advantages and let early adopters sell it for you.
