Advanced Client Load Balancing with Spring Cloud

on YouTube ↗48m

" summary

Live demo shows how to use Ribbon and Spring Cloud filters and rules to turn a naive round‑robin into a resilient client balancer: implemented circuit breaker filtering, response‑time weighted rule, best available and zone affinity filters, and a zone‑preference fix. Demo runs multiple instance containers, visualizes metrics on a Hystrix dashboard, cuts error rate from ~25% to near 0% under moderate load, and sustains ~90–120 RPS before failures. Also explores speculative parallel requests to improve perceived success probability.
