概述
云成本优化工作流是一个高级难度的工作流。分析云支出，识别浪费，在不牺牲可靠性的前提下实施成本优化。该工作流的目标是：Reduce cloud costs by identifying and eliminating waste.
环境准备
执行本工作流需要以下环境：Cloud provider billing data and cost explorer；Resource inventory with usage metrics；Access to resize or terminate resources。请确保在开始前准备好所有必需的工具和资源，以避免中途因环境问题中断。
执行步骤
本工作流包含5个步骤。步骤1：Analyze spending——Review cost breakdown by service, resource, and tag to identify the biggest cost centers. 步骤2：Find idle resources——Identify idle or underutilized resources: unattached volumes, stopped instances, unused load balancers. 步骤3：Right-size resources——Resize overprovisioned resources based on actual usage patterns. 步骤4：Use spot or reserved——Switch eligible workloads to spot instances or purchase reserved capacity for steady-state. 步骤5：Set up alerts——Configure billing alerts to catch cost spikes early.
验证与清理
预期结果：Cloud costs are reduced by eliminating waste and optimizing resource allocation.。验证方法：Compare monthly costs before and after optimization; confirm no service reliability was impacted.。清理操作：Revert resource changes if they cause performance issues; monitor after each change.。estimatedMinutes 为 120 分钟。
