# PERF01-BP03 制定架构决策时考虑成本因素
<a name="perf_architecture_factor_cost_into_architectural_decisions"></a>

 制定架构决策时考虑成本因素，以便提高云工作负载的资源利用率和性能效率。意识到云工作负载的成本影响时，就更有可能充分利用有效资源，减少浪费。

 **常见反模式：**
+  只使用一个系列的实例。
+  没有对照开源解决方案对许可的解决方案进行评估。
+  没有定义存储生命周期策略。
+  没有查看 AWS 云 的新服务和功能。
+  只使用数据块存储。

 **建立此最佳实践的好处：**通过在制定决策时考虑成本因素，可以让您使用更有效的资源，并探索其他投资方式。

 **在未建立这种最佳实践的情况下暴露的风险等级：**中 

## 实施指导

 针对成本优化工作负载能够提高资源利用率，避免在云工作负载中出现浪费。要在制定架构决策时考虑成本因素，通常包括合理调整工作负载组件的大小和实现弹性，从而提高云工作负载的性能效率。

### 实施步骤
<a name="implementation-steps"></a>
+  制定成本目标，如云工作负载的预算限额。
+  确定会增加工作负载成本的关键组件（如实例和存储）。可以使用 [AWS 定价计算器](https://calculator.aws/#/) 和 [AWS Cost Explorer](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/) 来确定工作负载中的关键成本驱动因素。
+  了解云中的[定价模式](https://aws.amazon.com/pricing/)，例如按需型实例、预留实例、节省计划和竞价型实例。
+  使用 [Well-Architected 成本优化最佳实践](https://docs.aws.amazon.com/wellarchitected/latest/cost-optimization-pillar/welcome.html)来优化这些关键组件的成本。
+  持续监控和分析成本，发现工作负载中的成本优化机会。
  +  使用 [AWS Budgets](https://aws.amazon.com/aws-cost-management/aws-budgets/)，针对无法接受的成本获取相关提醒。
  +  使用 [AWS Compute Optimizer](https://aws.amazon.com/compute-optimizer/) 或 [AWS Trusted Advisor](https://aws.amazon.com/premiumsupport/technology/trusted-advisor/) 获取成本优化建议。
  +  使用 [AWS 成本异常检测](https://aws.amazon.com/aws-cost-management/aws-cost-anomaly-detection/)自动进行成本异常检测和根本原因分析。
