Your question is Forecasting Cloud Hosting Costs. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you model and forecast hosting costs (such as AWS or Google Cloud expenses) as Datadog scales its customer base?
Please explain the cost drivers, required data, forecasting methodology, treatment of fixed and variable costs, and how you would validate the model. Discuss how you would present scenarios and identify actions that could improve hosting-cost efficiency.
