🧪 Technology System Design Simulation

This simulation demonstrates the principles of system design by modelling a real distributed-systems building block: a load balancer routing a Poisson stream of requests across a bank of backend servers, each with its own FIFO queue and finite service capacity. Choose between Round Robin, Least Connections and capacity-Weighted Random routing, dial in arrival rate and server heterogeneity, and even fail a server mid-run to see how each strategy adapts. Live readouts track throughput, average latency, peak queue depth and dropped-request count — the same metrics a real infrastructure dashboard shows — so you can see directly how routing strategy and traffic shape overall system stability and performance.
