The Show Must Go On: Securing Netflix Studios At Scale

In 2017, Netflix Studios was hitting an inflection point from a period of merely rapid growth to the sort of explosive growth that throws “how do we scale?” into every conversation. The vision was to create a “Studio in the Cloud”, with applications supporting every part of the business from pitch to play.

Partnering to Productize Security

Jose & Arthur (Netflix Cloud Gateway): The Cloud Gateway team develops and operates Netflix’s “ Front Door ”. Historically we have been responsible for connecting, routing, and steering internet traffic from Netflix subscribers to services in the cloud. Our gateways are powered by our flagship open-source technology Zuul.

Killing the Checklist

Once we worked together to integrate our SSO with Wall-E, we had established a pretty exciting pattern of adding security requirements as filters.

The Early Adopter Challenge

Wall-E’s early adopters were handpicked and nudged along by the Application Security team. Back then, the Cloud Gateway team had to work closely with application developers to provide a seamless migration without disrupting users. These joint efforts took several weeks for both parties.

Scaling With Developer Experience

Developers in the Netflix streaming world compose the customer-facing Netflix experience out of hundreds of microservices, reachable by complex routing rules. On the Netflix Studio side, in Content Engineering, each team develops distinct products with simpler routing needs.

Going Faster, Faster

As all of these pieces came together, app teams outside Studio took notice. For a typical paved road application with no unusual security complications, a team could go from “git init” to a production-ready, fully authenticated, internet accessible application in a little less than 10 minutes.

From Product to Platform

You may have noticed a word sneak into the conversation up there… “platform”. Netflix has a Developer Productivity organization: teams dedicated to helping other developers be more effective. A big part of their work is this idea of harvesting developer intent and automating the necessary touchpoints across our systems.
