summary

Flux uses RPC tracing to attribute backend capacity to products, feeds those attributions into a joint mixed-integer programming solver that simultaneously assigns service capacity and product traffic, and then executes plans via a capacity orchestrator tied to autoscaling and traffic systems. It runs in 20+ regions, has operated ~2.5 years serving thousands of services, produces plans in ≈5 business days and executes them in ≈10, and supports hardware refresh and global utilization rebalancing while shrinking disaster buffers.
