Which Azure feature lets a CIO visualize spending trends and forecast future cloud expenses?

Azure Cost Analysis, part of Azure Cost Management + Billing, is the correct feature. It provides tools to analyze spending trends, create budgets, and forecast future costs across your Azure resources. This allows CIOs and financial teams to gain insights into cloud expenditures and make informed decisions. Azure Policy is used to enforce organizational standards and assess compliance, not for cost visualization. Azure Monitor collects and analyzes telemetry data from Azure resources and on-premises environments to maximize their performance and availability, but it doesn't primarily focus on financial cost analysis. Azure Security Center (now Microsoft Defender for Cloud) provides unified security management and advanced threat protection, which is unrelated to cost visualization.
