DoorDash Uses Envoy and Valkey for a 1.5M RPS Proxy Cache with 99.99999% Availability

Operating within DoorDash’s service mesh, the platform serves over 1.5M requests per second with 99.99999% availability through caching, event-driven invalidation, failure handling, and performance optimizations.
