AWS re:Invent 2018: Scaling Push Messaging for Millions of Netflix Devices (ARC334)

Опубликовано 27 ноября 2018, 19:13

Netflix built Zuul Push, a massively scalable push messaging service that handles millions of always-on, persistent connections to proactively push time-sensitive data, like personalized movie recommendations, from the AWS Cloud to devices. This helped reduce Netflix’s notification latency and the Amazon EC2 footprint by eliminating wasteful polling requests. It also powers Netflix’s integration with Amazon Alexa. Zuul push is a high-performance async WebSocket/SSE server. In this session, we cover its design and how it delivers push notifications globally across AWS Regions.  Key takeaways include how to scale to large numbers of persistent connections, differences between operating this type of service versus traditional request/response-style stateless services, and how push messaging can be used to add new, exciting features to your application.
