Zalando Builds In-Process Client-Side Load Balancer for High-Scale APIs
Zalando described how its engineering team designed and implemented an in-process, client-side load balancer for an API handling about 1 million requests per second. The approach improved latency predictability, reduced infrastructure costs, and made it easier to identify the real source of failures.
