There are many possible failure modes, and each exercises a different aspect of resilience. Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. This is why most AWS regions have three availability zones.

You might say that the outcome of this exercise is a performant predictive model. Second, this exercise in model-building was … rather tedious? Instead of invoking the open-source scikit-learn or Keras calls to build models, your team now goes from Pandas data transforms straight to … the API calls for AWS AutoPilot or GCP Vertex AI.

Netflix operates in multiple AWS regions. MezzFS collects metrics on data throughput, download efficiency, resource usage, etc. We parallelize rerun jobs with Titus , Netflix’s container management platform, which allows us to exercise many hundreds of replay files in minutes.

Where other systems may take over ten minutes to process metrics accurately, Mantis reduces that from tens of minutes down to seconds, effectively reducing our Mean-Time-To-Detect. Mantis Makes It Easy to Answer New Questions The traditional way of working with metrics and logs alone is not sufficient for large-scale and growing systems.
