Harness significantly reduced its cloud spending by 40% through a proactive, engineering-led approach to cost management, shifting from a reactive, top-down oversight. This strategy involved empowering engineers with detailed cost visibility and accountability, allowing for impactful infrastructure optimizations. Harness implemented changes such as managing cloud costs on an hourly basis, providing engineers with tools to correlate deployments with financial impact, and setting up cloud budgets with monthly usage alerts. These efforts resulted in substantial savings, reducing monthly costs from $100,000 to $60,000, and inspired the development of their Cloud Cost Management software to help other organizations achieve similar results. Examples of success include customers like Relativity and GoSpotCheck, who achieved significant savings by addressing inefficiencies and idle costs.
