Infrastructure efficiency: How a classic math problem helped reduced our capacity buffers
LinkedIn engineers explain how they applied the newsvendor problem, a classic inventory-management model, to right-size capacity buffers for their private cloud infrastructure. By combining demand forecasting, signal cleaning, and multi-plexing of headroom and overhead buffers, they achieved an 8.5% reduction in required capacity buffers for their stream-processing platform, without sacrificing reliability. The approach separates organic demand variability from planned step-changes, accounts for lead-time volatility in a private cloud (versus public cloud elasticity), and treats infrastructure capacity like a supply chain problem. The methodology is now being extended across LinkedIn's broader infrastructure ecosystem.
