Service throttling Zuul can sense when a back-end service is in trouble by monitoring the error rates and concurrent requests to that service. Those two metrics are approximate indicators of failures and latency. Netflix experienced a similar issue with the same potential impact as the outage seen in 2019.

If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Additionally, it became easy to provide deep links to different monitoring and deployment systems in Edgar due to consistent tagging.

In 2019, Netflix moved thousands of container hosts to bare metal. Netflix runs dozens of stateful services on AWS under strict sub-millisecond tail-latency requirements, which brings unique challenges. By watching applications for anomalous actions, security and operations teams can monitor unusual and erroneous behavior.

In all cases we need to be able to carefully monitor the impact on the system, and back out if things start going badly wrong. Two failure modes we focus on are a service becoming slower (increase in response latency) or a service failing outright (returning errors). Automating chaos experiments in production Basiri et al.,
