Behind these perfect moments of entertainment is a complex mechanism, with numerous gears and cogs working in harmony. This is where large-scale system migrations come into play. By tracking metrics only at the level of service being updated, we might miss capturing deviations in broader end-to-end system functionality.

In particular, it’s our job to design and build the systems and protocols that enable customers from all over the world to sign up for Netflix with the plan features and incentives that best suit their needs. Let’s take a deeper look at the architecture, protocols, and systems involved.

Our streaming teams need a monitoring system that enables them to quickly diagnose and remediate problems; seconds count! Our Node team needs a system that empowers a small group to operate a large fleet. For example, a latency increase is less critical than error rate increase and some error codes are less critical than others.

It’s been clear for a while that software designed explicitly for the data center environment will increasingly want/need to make different design trade-offs to e.g. general-purpose systems software that you might install on your own machines. The desire for CPU efficiency and lower latencies is easy to understand. Enter Google!

To reduce latency, assets should be generated in an offline fashion and not in real time. Here’s what the final architecture looked like.

Over the years, we have built a recommendation system that uses many different machine learning algorithms to create these personalized recommendations. All of these algorithms and logic come together in our page generation system to produce a personalized homepage for each of our members, which we have outlined in a previous post.
