🧪 Deployment Simulation

This simulation demonstrates the process of deploying software applications as a real deployment pipeline: commits arrive as a random stream, queue for Build, Test and Deploy stages each staffed with a limited number of parallel workers, and either complete successfully or get bounced back for a retry by a failing test. Tune the arrival rate, per-stage worker capacity and test failure rate and watch how queueing theory predicts exactly which stage becomes the bottleneck — illustrating how different deployment-pipeline capacity choices impact throughput, release latency and system availability under load.
