I had been running a 2-vCPU ECS instance 24/7 to serve an API that processed maybe 200 requests per hour, paying around 490 CNY/month. The same workload on Function Compute cost under 5 CNY/month. Not 5 CNY per day — 5 CNY per month. The math was so lopsided that I spent the next weekend migrating everything that did not need a persistent process off ECS and onto functions.</p>
