As your cloud spend starts to increase, being able to accurately forecast usage becomes a critical part of your plan. As the first step in enabling a forward looking view to your spend on a subscription we’re launching a forecast API. The forecast API today supports a daily or monthly grain forecast at a 95 percent confidence interval.
The API also returns the last two months of actual usage that should help in looking at any trending scenarios. For future iterations of the API, we plan to support multiple other scopes up and down the hierarchy, like resource groups and enrollments, options for confidence intervals and longer range forecasts. Check out the documentation page for more details on calling the forecast API.
