I don’t advocate “Serverless Only”, and I recommended that if you need sustained high traffic, low latency and higher efficiency, then you should re-implement your rapid prototype as a continuously running autoscaled container, as part of a larger serverless event driven architecture, which is what they did.

How is monitoring different from observability? Already in the 2000s, service-oriented architectures (SOA) became popular, and operations teams discovered the need to understand how transactions traverse through all tiers and how these tiers contributed to the execution time and latency. Observability vs. monitoring.

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.

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.,

If your latency is higher than 50ms, users may perceive your app as laggy. How should the metric comparison be output to the console?
