The container inside serverless
summary
The talk shows that serverless platforms still run real container images: code is turned into Docker images and the OpenWhisk action loop plus a Jean-Loup proxy pipe stdin/stdout to language runtimes. It demonstrates building and inspecting Docker containers, compiling actions into precompiled ELF binaries in a zip to avoid cold starts, and orchestrating functions using Kubernetes and Kafka, with live demos exposing init and exec timing via scripts and hooks.
