To this end, we developed a Rapid Event Notification System (RENO) to support use cases that require server initiated communication with devices in a scalable and extensible manner. In this blog post, we will give an overview of the Rapid Event Notification System at Netflix and share some of the learnings we gained along the way.

Those events are then retrieved by the Team Service, which stores all allowed requests into an event registry and collapses that request history into the current state of a team upon receipt of a READ request. This approach also minimizes network traffic throughout the architecture, as all external calls are handled by this service.

Each HTTP request that is required for the page needs to travel over the network and in turn this consumes energy on both the server and client. While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. It’s a win-win all round!

For systems that are latency sensitive, creating two independent ways to succeed is an important technique for greatly reducing the 99th percentile latency.
