Removing uncertainty through "what-if" capacity planning

What this post added

This post introduces "Scenario Planner," a new system for capacity planning that allows internal teams to simulate "what-if" scenarios related to demand and supply changes across Cloudflare's global data centers. It details the system's inputs (demand and supply changes), calculations (conversion to CPU Time and distribution across regions), and outputs (heatmaps and "Expected Failovers" views). The post also elaborates on the importance of CPU Time as a unit of measurement for capacity planning and provides examples of demand and supply "what-if" questions and their corresponding inputs and calculations within Scenario Planner.
