Core Capabilities
核心能力
1. Cost Inventory
1. 成本清单
Catalog infrastructure costs by:
- Service category: Compute, storage, database, networking, observability, etc.
- Environment: Production, staging, development, CI/CD
- Team/Product: Which team or product area owns the spend
按以下维度梳理基础设施成本：
- 服务类别：计算、存储、数据库、网络、可观测性等
- 运行环境：生产、预发布、开发、CI/CD
- 团队/产品：哪支团队或产品领域承担该支出
2. Efficiency Metrics
2. 效率指标
Track key efficiency metrics:
| Metric | Formula | Target |
|---|---|---|
| Infra as % of revenue | Monthly spend / MRR | <20% early stage, <10% at scale |
| Cost per customer | Infra spend / active customers | Should decrease over time |
| Compute utilization | Actual usage / provisioned | >40% average |
| Cost per request | Infra spend / total requests | Should be stable or decreasing |
跟踪关键效率指标：
| 指标 | 计算公式 | 目标值 |
|---|---|---|
| 基础设施支出占营收比例 | 月度支出 / MRR | 早期阶段<20%，规模化后<10% |
| 单客户成本 | 基础设施支出 / 活跃客户数 | 应随时间逐步降低 |
| 计算资源利用率 | 实际使用量 / 已配置量 | 平均>40% |
| 单请求成本 | 基础设施支出 / 总请求数 | 应保持稳定或逐步降低 |
3. Waste Detection
3. 浪费识别
Identify common waste patterns:
| Waste Type | What to Look For |
|---|---|
| Idle resources | VMs, databases running but unused |
| Over-provisioned | Resources sized larger than needed |
| Dev/staging bloat | Non-prod environments at prod scale |
| Zombie resources | Old resources no longer needed |
| Data hoarding | Storing data that's never accessed |
| Unoptimized data transfer | Excessive cross-region or egress traffic |
识别常见的资源浪费模式：
| 浪费类型 | 检查要点 |
|---|---|
| 闲置资源 | 运行但未被使用的VM、数据库 |
| 过度配置 | 资源规格超出实际需求 |
| 非生产环境冗余 | 非生产环境配置与生产环境规模一致 |
| 僵尸资源 | 不再需要的陈旧资源 |
| 数据囤积 | 存储从未被访问的数据 |
| 未优化的数据传输 | 跨区域或出口流量过大 |
4. Optimization Recommendations
4. 优化建议
For each waste item:
- What: Specific resource or pattern
- Current cost: Monthly spend
- Potential savings: Estimated monthly savings
- Effort: Easy / Medium / Hard
- Risk: Low / Medium / High
- Action: Specific steps to optimize
针对每个浪费项，需包含：
- 内容：具体资源或模式
- 当前成本：月度支出金额
- 潜在节省：预计月度节省金额
- 实施难度：简单 / 中等 / 困难
- 风险等级：低 / 中 / 高
- 行动方案：具体优化步骤
5. Cost Forecasting
5. 成本预测
Project future costs based on:
- Growth in customers/users
- Planned infrastructure changes
- Historical cost trends
- Upcoming product launches
基于以下因素预测未来成本：
- 客户/用户增长情况
- 计划中的基础设施变更
- 历史成本趋势
- 即将发布的新产品
