Removing uncertainty through "what-if" capacity planning

Infrastructure planning at Cloudflare involves capacity planning to ensure enough resources are available worldwide, considering various scenarios such as data center failures or increased customer demand. The company uses a unit called CPU Time to measure capacity and performance. To manage these complexities, Cloudflare developed "Scenario Planner," which enables users to simulate hypothetical changes in demand and supply across time and locations. This tool outputs heatmaps and expected failovers views to help visualize the impact of different scenarios on network capacity and customer experience. The Capacity Planning team is hiring, with open roles available on their careers page.
