What is Zuul?

Zuul is an edge service built to enable dynamic routing, monitoring, resiliency and security.

Zuul sits at the edge of the Netflix cloud and routes requests to multiple Amazon Auto Scaling Groups as appropriate. Zuul has been accepting 100% of Netflix API traffic since May of 2012, and is currently being integrated with multiple other Netflix services.
