The traditional Prometheus configuration makes several assumptions about the architecture of the systems that it is monitoring that fail to be met in the world of Serverless Architectures. With the increasing adoption of Serverless computing in Distributed Systems architectures, the question then arises of how to achieve the same insight into them that we can achieve with more traditional architectures. In particular, with Timeseries Metrics, the choice is often to choose between substandard upstream offerings (such as the Prometheus Pushgateway), or capitulate to vendor lock-in and utilise a platform provided by your Cloud provider. So if we want to continue to use our existing Prometheus systems, then what choices do we have? This talk will cover the issues around existing solutions, Colin's solution to these issues that is currently in production at Cloudflare, and where we can go in upstream to make the experience better going forward.Click here to view captioning/translation in the MeetingPlay platform!
