We recently made a major architectural change to Zuul, our cloud gateway. Did anyone even notice!? Probably not... Zuul 2 does the same thing that its predecessor did -- acting as the front door to Netflix’s server infrastructure, handling traffic from all Netflix users around the world.

The major architectural difference between Zuul 2 and the original is that Zuul 2 is running on an asynchronous and non-blocking framework, using Netty. After running in production for the last several months, the primary advantage (one that we expected when embarking on this work) is that it provides the capability for devices and web browsers to have persistent connections back to Netflix at Netflix scale.
