Modern HTTP Routing
summary
Zalando runs more than 80 Kubernetes clusters and uses an HTTP router called skipper that implements predicate route matching plus filters that modify headers and bodies and export metrics in JSON. The stack supports deployment patterns like blue-green deployments and A/B tests, and it can mirror production requests as shadow traffic so preview services see live load without affecting users. The router also implements retries, circuit breakers and adaptive rate limits that account for autoscaling backends and changing load balancer instances.
