Lightning Talk: Rethinking Microservices
summary
Argues microservices are not a universal goal, cites a poll with 17% doing microservices, 54% happy with monoliths, 12% reverted, and stresses day‑two ops, OpenAPI contracts, 12‑factor and telemetry. Recommends tools: Open Liberty, Mono to Micro AI, MicroProfile/Jakarta EE, GraalVM and CRIU/instant‑on via OpenJ9. Demonstrates an instant‑on snapshot that turns a 5s Java cold start into 358 ms, and shows k‑native cold starts dropping from ~10s to ~3s—practical, working fixes for Java serverless.
