How the economics of multitenancy work
CI is chaotic, bursty, spiky, and short-lived. That chaos is a nightmare unless you’re built for it. Blacksmith’s serverless CI cloud thrives on unpredictability: more customers = more noise = smoother utilization = lower costs for everyone. Multitenancy isn’t just efficient — it’s profitable. And yes, the margins are…
