云成本优化

# 先解释账单，再决定该削减什么

云支出下降并不一定意味着效率提高，也可能只是业务量减少。我们把费用与实际工作负载联系起来，找出可执行的改进，并保留性能和恢复能力的边界。

合作方式

## 每项节省建议都应有条件和验证方式

1. **分析起点** 账单、资源清单、使用指标、合同承诺及服务约束。
2. **交付内容** 成本归因、优先级清单、约定优化的实现和前后对比记录。
3. **验收方式** 比较可比工作量下的费用与运行表现，区分估算和已观察结果。

服务说明

Wavect 分析并优化现有云环境的成本，用工作量和可靠性数据判断每项变化是否值得保留。

适合的情况

- 云账单增长但缺乏清晰归因
- 希望在现有环境中减少浪费

其他需求

- 主要目标是迁移云平台或数据中心

## 把支出分配到真正使用资源的工作负载

我们梳理账单、标签、共享服务和环境归属，区分固定费用、使用费用及已有承诺。成本基线应能解释哪些服务、团队或业务活动造成变化，也记录暂时无法合理分摊的项目。

本服务针对现有环境的效率。如果主要问题是基础设施位置或迁移路径，应由 [云迁移](/zh/services/cloud-migration/) 界定范围。不能把换平台本身当作已经证实的节省方案。

## 检查闲置资源，也检查持续发生的小额浪费

分析可能覆盖闲置实例、过度预留容量、存储生命周期、日志保留、数据传输、数据库配置和非生产环境运行时间。每项建议都应记录预期影响、实施难度、服务风险和适用前提。

预付或长期承诺可能改变费用结构，但也可能降低灵活性。购买决定需要业务负责人批准，并结合稳定需求与合同条件判断；不会仅因为折扣存在就建议增加承诺。

## 成本优化不能悄悄改变恢复要求

我们与服务负责人确认性能、备份、保留、可用性和安全约束，再按批次实施调整。对于容量或运行时间变化，应设置观察窗口、异常阈值和回退方法。

删除资源前需要核实依赖和数据责任。减少日志或备份尤其要检查调查、恢复与合规需求。访问和保护要求属于 [云安全](/zh/services/cloud-security/) 的边界，不能为了降低账单而被默认放宽。

## 更便宜的批处理，也必须按时正确完成

以下为评估方案的示例，而非客户节省业绩：一个批处理任务切换到更经济的资源配置。验收不仅查看小时单价，还要检查是否在约定期限内完成、失败重试是否增加，以及输出是否正确。

比较应使用每次成功任务的总成本，并包含失败尝试和相关传输费用。如果资源更便宜却导致大量重试，方案就不能仅凭单价被判定有效。

## 明确哪些是估算，哪些已经出现在账单里

报告分别列出预测变化、已实施事项和观察到的费用差异。对比应尽量考虑业务量、运行时长、折扣、币种和季节性，解释不能直接比较的部分。

一个观察周期未必足以判断长期效果。我们不会把一次账单下降描述成永久节省，也不会把尚未批准或实施的建议计入已实现结果。

## 把成本管理接入日常工程工作

交付包含归因规则、优化记录、预算或异常提示的约定配置，以及由谁复查新资源的责任说明。 [DevOps 与平台工程](/zh/services/devops-platform-engineering/) 可以把环境期限、模板默认值和资源清理加入开发流程。

持续监控与值班响应需要另行约定 [云托管运维](/zh/services/managed-cloud-operations/) 。一次成本优化项目并不自动提供长期账单管理或全天候基础设施保障。

## 开始前的常见问题

### 是否会保证固定比例的节省？

不会。可优化空间取决于当前资源、需求、合同和服务约束。我们先识别机会，再区分估算、实施与实际观察到的结果。

### 优化是否意味着迁移基础设施？

不一定。本服务可以在现有云平台上调整容量、生命周期、运行安排和配置。迁移涉及不同的架构与切换风险，应单独确定范围。

### 需要提供哪些访问权限？

初期通常先使用账单、资源与指标的只读信息。实施阶段再按任务约定最小必要权限和审批流程，避免通过公开表单传递凭据。

### 如何避免业务增长掩盖优化效果？

可以选择与工作量相关的指标，例如每次成功任务或每笔已处理交易的成本，并同时记录总费用。具体指标取决于可用数据及服务用途。
