The Hidden Magic Of Extensions

The Hidden Magic Of Extensions

Mar 2, 2022

As serverless architectures start to grow, finding the right troubleshooting approach becomes a business-critical aspect. This talk will dive into "the instrumentation approach" - keep track of internal events on the lambda and export processed telemetry data.

We should handle legacy code, multiple code owners, and a massive stack of serverless technologies as with any real-life project. Our goal is to write as least code as possible, avoid any existing code changes, be cross-runtime, and leave no latency impact.

This talk will be a practical guide to using extensions. We will extract internal events from lambdas, process, and send telemetry to external services, regardless of the lambdas' runtime. Minimal latency hit will be in our highest interest.
