Serverless Platform for Large Scale Mini-Apps: From Knative to Production

on YouTube ↗39m

" summary

Ant Financial describes a production serverless stack built on Knative that fixes cold starts, cost and scale. They implement a pod pool prewarm that injects code into standby pods via CRDs and a code loader or a forked kubelet container substitution to swap containers at runtime, cutting Java cold start from about 20 seconds to 1.8 seconds (~90% faster). Multi tenancy uses shared control plane with namespace or per-tenant etcd directories, Kata containers for isolation, and controller sharding via labels plus DNS and service mesh submeshes for horizontal scale.
