Day 3
summary
Four short demos give concrete takeaways: Envoy sidecar with Lua filters shows a Docker Compose demo (Python Flask product + Java inventory) using Keycloak JWT auth and per-pod Envoy configs that proxied and logged requests; Lua and JWT filters work but add config complexity. Micronaut compile-time AOT beans highlights compile-time bean generation, introspection, refreshable scope, and testing notes (faster runtime, longer compile, smaller community). A human-factors talk codifies chunking with a 4-item working memory rule and "rubber‑duck design" exercises. Platform piece pushes Java 21 + virtual threads + native image: records/sealed types, JDBC client, declarative HTTP clients, buildpacks, 100k virtual‑thread demo and an 86 MB native binary.
